Review: Kogalla solar bank

I love my portable batteries. mostly because I love my power-hungry iDevices and not only go to a lot of long meetings, but also occasionally camping trips and other away-from-the wall outings! Having portable power not only extends my mobile browsing and picture snapping abilities, but also makes me a hero when someone else is trying the same and didn't think to prepare.

However, even battery packs like the hefty Limefuel Limeade with its 18000mah
are only as good as their capacity. Once dry, they're done, which is why I am also really keen on alternate power sources , especially in the event of a long term power outage. My favorite power source is solar, being free, non polluting and very sustainable.

I also love it when two great flavours like this mix, such as in the Kogalla solar storage bank. The SSB2210 Solar Storage Bank is a high-energy, ultra-slim power bank matched to a high-efficiency foldable solar panel housed in rugged, waterproof fabric body.

Unfolding exposes four solar panels each roughly the size of the iPad Air 22cm (8")x 13cm (5") x 3.5cm (1 1/4") compared to (24 cm (9.4") (h) 16.5 cm (6.67") (w) 7.5 cm (0.30") (d)) and when fully unfolded it stretches out to an overall 61cm (24") when fully deployed the SSB2210 offers a huge 22 W capture capacity s worth of panels which allows for fast charging times in full sunlight.  Matching the panels to the power bank allows for energy harvesting even in low-sun conditions. 920g (2lbs) n not bad at all, considering both the panels AND battery in one.

Not unfolding the panels limits the capacity but reduces the footprint required. given that the four panels fold nicely and will constantia a bit to allow it to stand up whilst exposing more panels to the sun. This is also important when it comes to getting a good angle to the sun.

Maximum possible solar generation at your location is possible by angling the panels to the angle of the latitude at which you are located. In Melbourne, that would be 38°. You would ideally want to angle your panels at a greater tilt for maximum exposure to the low winter sun. 

The general rule of thumb is that panels angled at the latitude angle, plus 15°, is best to maximise winter sun exposure. Obviously placing the panel in the line of the sunlight is the other part of this equation. Direct sunlight is best but even dappled or overcast  sunlight will generate power, slowly trickle changing the on-board battery. 

The 10,000 mAh power bank provides long battery life between charges. The power bank can also be charged through a micro-USB power input for charging during no-sun conditions. from a wall socket tor other alternate power source like

Dual high-current USB power ports (up to 12 W) lets you power lights, accessories, or fast-charge devices. The unit folds into a compact, ultra-portable kit that includes a zippered pouch for accessories. The kit also includes a flexible-neck USB light, micro-USB cable, and lightning cable. For the charging of all kinds of devices. I especially like charging my USB chargeable flashlights and phone in a modern "make hay whilst the sun shines" situation. I also charge up my other batteries for the same reasons.

I've found that I can charge either an iPad or an iPhone but not both simultaneously, now, doing some research i find that the  An iPhone charger delivers 5 Watts (5 volts at 1000 mA) and the Retina iPad mini charger delivers 10 watts (5.1 volts at 2100 mA). so its not unreasonable to see that 5W + 10W is more than the 12 W output of the  SSB2210. Bearing that in mind, just like the Apollo 13 Mission Control team, do the math and know how much draw your gear is going to make on your batteries. Matching the panels to the power bank allows for energy harvesting even in low-sun conditions, but they can only do so much. Luckily I also have a dedicated iPhone solar charger...

Another neat feature of the SSB2210 is the fabric eyelets sewn into the middle of the unit and the four corners. These loops allow the solar panels to be lashed down into optimum position or onto something either for stability or portability. I lashed it to the side of my rain-fly one day, and also to the back of my hiking pack, such that my daylight hike would serve double duty of also charging batteries on the bounce.

I used four mounting points to fix it to my pack here, but left the bottom panels free-hanging.

 I knew I would need to be mindful of the panels when I shucked my pack, but it wasn't any drama at all on an hour long hike.

I generally keep this unit folded up and in the hydration bladder pocket of my day to day pack, ready to charge up my devices on the go, or to pull out and make myself a hero during long meetings.

 I can highly recommend it, especially as an off-grid power source in a sunny environment to keep your vital gadgets alive. I would couple it with other power generation and storage items such as the Beacon or the like. Diversify and empower yourself!

Review: Outdoor Expedition - Universal Solar Multi-Bottle

Passing by a closing-down sale at a local camping goods outlet store I wandered in and snapped up a couple of deep-discount bargains, which included a pair of the Universal Solar Multi-Bottle which I thought would make excellent camp-lanterns, specifically for Tactical Baby and Triceratops Girl.

What drew me to them was that the "bottle" component was a squishy, pliant silicone material, making it drop-bounce, trip and generally woops-prone kid proof.

We don't all get out camping together very often, but even around the Bunker, we often go on night-time expeditions. There is a Tawny Frogmouth Owl nesting in a big tree down the block, and the stroll out to listen to it's call is made much jollier (and safer for little people on the pavement) by their very own light.

The area Triceratops Girl lives in is prone to tree-fall power-outages, and the Bunker has some wiring problems, so we both experience blackouts, and having personal lights for the girls makes a possibly frightening inconvenience into a fun excuse for lanterns.

The Multi-bottle is constructed of a soft, collapsible TPE body  which can be squashed down for easy storage and transport, and has a hard plastic "cap" which houses the LED lights, the battery and the solar panel.

The solar panel is fitted to the centre of the lid, and is somewhat covered by the removable handle strap, which can be removed not only to expose the panel to sunshine for charging but also hook over any number of hanging points.

The on-off button is set into the top of the lid as well, and has a built in changing status light, saving space. When the lid is unscrewed you have access to the micro-USB changing slip, which is protected by a silicone plug.

I suspect you -could- store liquid in the bottle in a pinch, but I would worry about it getting into the charging port and shorting out. The unit is described as having a IPX7 waterproof rating, which is 30 minutes at 1m depth, but again, I suspect that is only from the outside, when sealed up. Good enough for any amount of weather or looking for your keys dropped into a pond, not for diving ...

The LED light has3 modes, controlled by the indicator-light button on the lid.: low/high/pulse. It is listed as having:
4 hour runtime at HIGH setting
10 hour runtime at LOW setting
and I infer it has ~days runtime on PULSE setting, it wasn't listed.

The outputs of the two settings weren't offered, but I didn't really notice a significant difference. If it was 75 lumen vs 100 lumen, there wasn't much in it.

Shining through the TPE bottle gave the lights a nice diffuse glow, as well as the bottle itself being a glowing ball, good for both seeing your immediate surrounds but also letting people see you, good news when the primary goal was putting it into small hands to carry around.
The handle clipped on and off at either end, and was not at all difficult for 5yo Tactical Baby to manipulate, or carry.

We don't typically genderise the kit for the kids, but as it happened, only the pink bottles were available at the sale. Green or blue are also available.

These bottles have a carry capacity of 725mL (44cu in) so you could also fit a bunch of small items in it to make a bug-out-jar type effect, although that would block out a bunch of the light the emitted, and you would want to watch out for pointy items. At the very least you can store its USB cord inside, so it's all ready to charge when you have a power-source handy.

These are neat little lights, perfect for little hands in the wilderness of the woods or suburbs.

Disaster Shopping Event: Kathmandu trip

I was wandering the streets recently, and passed one of the big-chain outdoors stores with a sale on, and thought I'd pop in to see what was what.  I thought I might do a new thing for a spot. I wandered around and found 6 items that I would want to grab and go with if a disaster was imminent. This wasn't a very well thought out thing, and I might do it differently next time, but the premise was: "if SHTF whilst out strolling, what would I grab and go with, right now". I had parked my car only a block away, I had my family with me (Omega, Lorin and Tactical Baby), so we already had a reasonable EDC and BOB capacity on-hand.

Dynamo Radio which gives you a portable and personally powered connection to the outside world, at least listening in. The Radio is recharged by turning the crank for 90 seconds (providing approximately 40 minutes of playback). It also features a torch, clock and alarm. It carries a IPX6 "Splashproof" rating, and even features an earphone jack (reducing your noise signature, and reducing power consumption).

 An internal rechargeable battery pack (2.4V/300mA) powers the radio two LR-44 button batteries run the clock, but it can It can run off AAA 1.5V batteries or be powered by an external DC3V adapter. It has a pretty standard frequency range (AM 540-1600KHz, FM 88-108 MHz). It weighs 200g and is pocket sized.

Phantom MTB v4 hydration pack caught my eye as a carry-it-all.
Lightweight & simple, with enough room for the essentials required for a short trip if we had to hump it. Its design encourages airflow & comfort, with airmesh harness and backing and and adjustable straps. It features a multi-tool organiser, waist strap for secure running or climbing, reflective come-rescue-me flashings, and is 2L hydration bladder compatible. It's construction is of some very lightweight materials, the main body being a P600D Oxford, the trim a N420D SC HD and the lining N210D Oxford, all materials are double polyurethane coated for waterproofing.  It weighs only 390g and this is telling, it's a pretty flimsy pack, compared to the usually mil-spec bags I'm used to, but it would have work well enough for what

With more storage and salvage in mind, as well as contamination reduction, I spied a
Dry Sac 3-pack, which would meet that need. Constructed of a light but tough 30D diamond patterned nylon ripstop with polyurethane coating. The three pack comes in three sizes: Large 48cm L x 33.5cm W, 8L capacity, medium 38cm L x 26.5cm W, 2L capacity and small 28.5cm L x 20cm W with 1L capacity. They are lightweight, durable, and water resistant with sealed seams. I really like dry-bags,  Its just a matter of stuffing them, rolling down the top a minimum of three times to cover the flap and folding back and clasping the Fastex buckles.

I also saw a pretty good little pocket sized Survival kit in a find-me Safety-Orange case the case's contents: Pencil, Waterproof paper, fire steel and striker, cotton wool (2pcs), button compass, whistle, survival mirror, Wire saw, a small multi-tool, snare wire, fishing kit, salt sachet (2pcs), safety pins (2pcs), duct tape, zip-lock polybag, braided nylon cord and a carabineer.

It's only 12cm x 10cm and weighs 186g, so would be a very quick way to bolster a survivors kit on short notice.


Power and light are key elements for even short term comfort in a disaster situation ,and can greatly improve morale which is where something like the LuminAid come into play
This is a solar powered, inflatable LED light, with a waterproof (IPX-7) solar cell, battery and LED lantern, which is housed in a PVC-free balloon, which makes it buoyant, and dissipates the light evenly, making it a lantern rather than a flashlight. The battery is fully charged after 7 hours of direct sunlight, and can retain its charge for up to three months, before needing a top up. 

It has two light settings, a 15 lumen glow, with 12 hours of illumination, and 30 lumens, with 6 hours of charge. The bladder is blown up by a valve, the same kind of valve seen on pool toys world wide. At 77g this is a simple innovation that would go a long way to driving back the chaos after a disaster, especially in a family situation. 

A second light also caught my eye, this time as a communal power source as well as light source. The Power source lantern has a Cree R5 LED 3W light with four lighting modes: high – 150 lumens; medium – 75 lumens; low – 13 lumens; flashing, with corresponding run times: high – 6 hours; medium – 12 hours; low – 94 hours. The lantern also features a USB output which can be used to connect and charge your digital devices as a power source. It features a rechargeable Li-ion 3300mAh battery offering DC 5V-1A Max output. 

The lantern can be placed on its base, hung by its built-in hook, or attached to metal via powerful built-in magnets. It also features a battery indicator and has a  IPX5 splash resistance rating. Being able to keep a phone charged can also be really useful and potentially life saving survival tool.

So, there is my quick summary of six items that caught my eye that I might grab, if I happened to be passing near a Kathmandu store in the outbreak of a sudden disaster. 

Wish Lust: Beacon- Waterproof,Solar Power Bank,Light and Signal Device

This is mostly a summary of published materials, for a cool piece of tech that I saw come up on Kickstarter, and wanted to pass along to you all, especially in light of my most recent camping adventures where we managed to keep most of our personal technology and lighting charged by a combination of solar and thermoelectric sources.

Smith & Bradley, the maker of tactical and sport watches representing three successful Kickstarter campaigns, has launched its fourth Kickstarter project, The Beacon is a unique outdoor survival box combining waterproof storage for electronics, solar charging, and LED beacon signaling. Enclosed in a light and rugged, efficiently sized package, the Beacon unleashes the power of solar energy to not only charge, but protect, electronic devices. Further, true to its name, the Beacon comes equipped LED lighting for both emergency situations and casual use as well.

These lights are not after-thought add-on's, but rather first rate lighting solutions.

The entire package is crush-proof, waterproof, submersible, and floats even with an electronic device enclosed.The Beacon represents a first-of-its-kind combination of charging, solar, lighting, and waterproof technology. The Beacon allows for storage of two typical mobile phones, contains 3 USB charging ports that can all be used at same time, and a Polymer lithium ion battery. The battery is charged either by traditional wall socket charging or through the Beacon’s high capacity solar panel on the top of the case. The Beacon goes beyond a mere gadget, or drugstore charger. It is a tool that is an absolute necessity for anyone who ventures outside of the urban jungle.
The Beacon is 17cm (6 3/4") x 11cm (4.5") and 5cm (2") thick The interior storage compartment is 27mm (1.06") deep. The Beacon weighs just 15 ounces The Beacon is fully waterproof and is designed to float either empty or with a device enclosed with a device on board.

As a sustainable solar energy source, the Beacon has a fully-enclosed and waterproof solar panel on the lid of the device. Depending on the amount of sunlight, the Beacon's 1.5 w solar panel can provide a full charge to the unit in 36 hours with a 17% conversion rate-meaning that and average iPhone will charge from zero in an hour and a half.
The Beacon may also be charged by a conventional wall outlet The Beacon uses a Polymer Lithium Ion battery to operate the lights and to charge electronic devices and has a 10,000 mAh rating.

 The top of the Beacon is fitted with 12 White High intensity LED lights and 8 yellow hue, low-intensity lights to retain adequate night vision and retain more charge. (TESTED visibility up to 1 mile in blinking mode). As to charging, the Beacon is equipped with three USB charging ports for phones and tablets.
The USB interfaces include 2 ports which are 5v 1.0A and, 1 port 5v 2.1A and the Beacon's built-in battery life indicator shows charge at 25% 50% 75% 100%.

So, it's a fairly well thought out device, I like that it can store and charge two devices simultaniously, securely, safe from both water and other environmental hazards.

Review: Power Practical - Practical Meter

Here's a very cool gadget that I backed via Kickstarter, and have added to my mobile power ensemble. I've previously covered power generating thermo-electric systems such as Tellurex tPod1
and the bioLite power generating campstove as well as some options for going solar.

I've also covered a couple of power units, such as the Snow Lizard SLXtreme-5 iPhone case and the Power Travellers Power Gorilla.


This is the Practical Meter which is a clever little in-line USB unit, which gives you a visual means of determining the power usage and output. The LED's built in give an indication of the number of Watts (0-10W, 0-2A) that is being drawn to a given device. This display is in two stages, blue LED's lighting up for 1-5W, and then with the flashing red LED indicating 6-10W.

This level of resolution enables the user to customise the output, either by adjusting cables for better USB version, or the power source. For example, with solar collectors, it would be possible to adjust the angle of the panel to catch the maximum solar output. The same would stand for a thermo-electric generator, or any USB source combination.


Having an adjustable and monitoriable source of power means that a survivor can tailor their resources to best serve their needs in the event of being cut off from reliable mains power. Whether it is solar, fire or from a variety of battery sources, with an item like the Practical Meter, you can at least see what you are getting. It's not a robust piece of tech, so needs to be treated with more care than a ruggedised piece of bug-out kit, but at 12g (0.4oz) it's a great value piece of tech to add to your "power-pack pack".

Review: Snow Lizard - SLXtreme 5 iPhone case

Attentive readers may recall the Kickstarter for the rugged, batter and solar powered phone case, the SLXtreme that I covered a while ago. You may also recall how I took it on the Tough Mudder twice last year but it didn't survive the second attempt.

The hinge cracked and I had some water leakage into the unit, temporarily shorting out my phone, and killing the unit. I was sad, because it was otherwise a great piece of kit, but I also realised that I had put it through a pretty arduous test for a phone case.
However, undaunted, when I saw that Snow Lizard had gone on to make a case for the iPhone 5 (which I had subsequently upgraded to) I got in touch with them to let them know that I was keen to put it through its paces, and they kindly sent me a replacement, in the form of the new and improved SLXtreme 5. In safety orange no less.

It features all the same aspects as the previous model: latch-locking top opening, press-button battery-check and solar power switch, 2,550 mAh battery, membrane speaker

and mic covers, rugged buttons for volume and "home" buttons, a lanyard loop, capacitive touch-screen membrane.  It also sports a thumb-screw bottom sealing latch, and an access port for both USB charging and for the headphone jack. Forward and read-facing camera ports allows for photo and video capture and selfies.

There had been significant improvements as well.The in-built battery is 550 mAh larger in capacity over the "4" version.

 The bottom access port is now tool-free access (even though previously all you needed was a coin), the main latch is now a two-part metal, rather than polycarbonate.

The most exciting new feature however was the headphone jack socket and adapter. With an o-ring sealed plug, and matching sealed adapter, it is possible to have the phone safely cocooned and waterproof, as well as having access to headphone and mic jacks, a feature I've missed since my yellow Walkman days

As with the previous model, the SLXtreme 5 is rated at IP-68 with an operational depth of two meters, so in theory you can take SLXtreme anytime you are in or around water. It doesn't float, however, so I kept mine well attached to myself with a lanyard of paracord. This "open" shot gives you an idea of the engineering used in this cases creation, and it certainly paid off.

having access to the USB port (not the Lightning port of the phone, mind) allows you to charge the phone and its built in battery, but not synch, as far as I can tell.

The main port includes optically clear and easy to clean lenses, padding and improved closing latches, as well as hinges, substantially stronger in design than the previous model, I was pleased to see.


The solar panel was also improved, with a more matte finish to the surface, and what looked to be improved collector crystals internally.


The finish and the feel of the case as a whole was a lot more refined, and with the extra metal hardware, and the changes to the bottom panel, I was really impressed with the design improvements the Snow Lizard team had put into the next model.

When I took the plunge, (so to speak), and took my phone in its new case into the warm waters of Fiji, I knew I was going to give it a good test. With its "2m" depth rating, I was trepidatious  about how it would survive the trip, but as you can see, it worked wonderfully.
I had to remind myself a few times to use the buttons to control photo operation, as the main screen doesn't work under water, but I was able to switch between still and video controls on the surface easily enough, with just a flick of the wrist to clear water from the surface.

I found that the edges were a little tight, when dealing with water droplets, for dexterous screen manipulation, but the macro-control I needed worked just fine. The phone was bone-dry after almost an hour in the water (and subsequent jet-ski back to the resort), and the footage turned out really well.

All in all, I am thoroughly pleased with my replacement SLXtreme 5 case, and would highly recommend them to anyone who wanted to do some wet and wild filming, mapping, long distance phone calls and catching up on your favorite Apocalypse Equippedness blog from a beach-side or mountain-top retreat with their trusty iPhone.

Review: Gearward - 24HSD glow tag

I saw these come up in one of my reader feeds, and saw that there was controversy about them, but felt I should check them out myself rather than just take a knee-jerk response.

I'm a big fan of both glow-in-the-dark kit, and signalling in general, and thought it would be worth your time and mine to cover an item such as this.

This is the 24 Hour Signal Device by Gearward, and it's a no frills day/night signalling tool.

You may recall the  SAR Eclipse Signal System I covered ages ago, and also the SAR MoonGlow disk. This product is in some ways like a combination of those two systems.

Combining a slab of the same moonglow plastic as in the SAR disks, and the terminatorized NukoTool ACDT and a mirror finished chrome tag which acts as a signalling mirror. It came bundled with a strip of ranger-band and a braided, waxed cord.

Both tags are in standard dog-tag size and shape and are drilled with a hole to use as a helioscope for signalling, much like the inner segment of the SESS-c.

Still, whilst it has many similar features, these are quite different products, and I have added this to my collection of EDC alongside the SAR systems and the similar, glowy UVPaqLiteUVP products.

I have added my 24HSD as a fob for my phone, seen here in its Strike Industries SHOX case.

More glow is good glow, as far as I am concerned. The big solid block of glowing plastic gave me many hours of illumination, both enough to find my phone, but also to navigate my keys and wallet contents in a dark room. I found it too bulky for me to add to my already prolific neck decoration collection, where as the SAR disk fits nicely there, but if just adding to an existing dog-tag, for example, it might well be just the ticket.

Shout out Review: PowerTravellers - Power Gorilla

Kevin Martin over at BreachBangClear has done a cool piece on a hefty ruggedized power-pack for charging his devices out in the field, for extended times.

Here's the link to his take on the PowerTravellers - Power Gorilla. This tablet sized battery boasts 20,000 mAh of charge, and you can see that Kevin put it through its paces in some pretty rough conditions.

I've covered a couple of power-generation devices in past, the thermoelectric Tellurex-tPod1, and a wish lust BioLight campstove to generate power, solar systems like those found on the SLXtreme iPhone case and the other small solar systems I have tried
but as yet haven't really covered how to STORE that power, other than in those built-in devices. Worth checking out Kevin's findings, for sure!

Review: HexBright - FLEX Programable light

I'm really excited to be bringing this one to you. This is another Kickstarter project that I backed ages ago, (Launched: May 21, 2011Funding successful : Jul 19, 2011) that finally arrived about a month ago. 

That's a long time, you might say. It was. However, creator Christian Carlberg made it up to me and all the other backers with his constant step-by-step updates, keeping us up to date with every design iteration, testing run and exchange of parts. The included videos of the whole process kept the faith, and my interest the whole, long, wait.

When it finally arrived, I was as thrilled as could be. This is the HexBright FLEX, open-source programmable, rugged, high-performance light. (Here, stacked up against my Surefire 6PX)

Christian pitched the HexBright as "a stylish, rugged, high-power compact light you can use as-is or reprogram however you want using open-source code." and yes, it is all those things!

 

The Flex has a max light output of 500 lumens thanks to the
CREE XM-L U2 LED super bright LED light source that sits at the pointy end behind the TIR Lens. The lens is made from PMMA, optical grade acrylic.

What does that give me? According to the Kickstarter page, and the Hexbright site, that means you have a High Mode output of 500 Lumens for 1 hour, a Medium Mode output of 175 Lumens for 8 hours or a Low Mode, 50 Lumens for 30 hours. Five HUNDRED Lumens. The Surefire 6Px is listed with a 200L output, and the 5-11 ATAC A1has a 103 Lumen output rating.

For those interested in color temperature, the FLEX sits at  5380K - which apparently is "just shy of daylight". Thanks to all that circuitry, you also have regulated light output, the light stays constant and has a 1.6amp max output, thanks to the USB rechargeable Lithium-Ion battery, which is apparently 3.7 VDC 2400 mAh, 4.8 Amp Protected). All that circuitry however, isn't just for power-metering, it also houses the programability of the unit.


The HexBright Flex comes shipped with default program modes of high (500 LM), medium (350 LM), low (200 LM), and blinky. but by plugging the FLEX into a computer via the micro-USB port, and then loading code with Arduino software. (You need to do some downloads first, both the USB drivers, the Arduino application and then the Arduino code files for whatever programs you want to run.

Part of the fun about this light is that versatility. As well as the press button at the tail-cap, the circuit board also has a temperature sensor, which can be used to monitor the lights heat for emergency shut-off due to overheating, but also can be used to report ambient temperature (reporting through flashes of the tail-button LED's). It also features a accelerometer which enables rotation and tap based signals to be used to govern the light (ie, rotate to dim or brighten, or tap to change settings, or message)

The inner housing rotates out via heavy set threads at the -tip- of the light, rather than the tail, which was a cool addition, and seals up with a well-seated o-ring gasket at the tail end. Accessing the USB port can be achieved by simply unscrewing the tail cap enough to expose it. It also means I can charge it via my solar chargers.
 

The body of the FLEX was machined from solid hexagonal aircraft-grade aluminium bar stock. both the tailcap, and the internal carrier body with its threaded end are made of the same stock, giving you a rock-solid construction. The tailcap button is a translucent rubber, also fully sealed, allows you to see the green and red status lights (charging, and mode-changing).

 
 At 145mm by 34mm, and weighing in at 215 g  (5.7" long by 1.3" , 7.6 oz) this is big for a pocket torch, but all that body houses the electronics, AND acts as a heat sink for the mighty CREE XM-L U2 LED. The knurled tailcap end is ever so slightly raised above the hexagonal sides of the main body, so the FLEX doesn't sit quite as flat as i'd have liked, but the meaty finger groves and that hexagonal body make it an ergonomic dream to wield or stuff a pocket with. A couple of narrow lanyard holes in the tailcap give you a carry-loop option.

Here's me doing a bit of an indoor test and comparison with my Surefire and ATAC A1, turning a cave into day.

Outside, the limitations of my iPhone to capture good night footage don't do the FLEX justice, but all the same, 500 Lumen is nothing to be scoffed at. I'm not sure if my car-headlights are this bright (bigger, yes, but as bright? I'm not sure).

Once I connected my FLEX to a PC, and messed around with the Arduino programs I found online, I settled with LOW-MED-HIGH, hold for flashy, hold and tap for strobe, and using the accelerometer, "go to sleep after 20 seconds of inactivity/wake on movement" for that "find your light in the dark tent" option. 

Going LOW-MED-HIGH at the tap of the button means I dont dazzle myself unnecessarily, or give my self away too badly if I am being careful about light discipline.  

Here's the comparison shots of the LOW-MED-HIGH settings indoors.

The HexBright FLEX is an awesome piece of engineering, I was really pleased to have received mine, even after the deliciously long wait, thanks to Christian's awesome updates and cute videos. This is definitely going into my EDC load, and my main concern is learn how to code new programs for it!

Review: Snow Lizard - SLXtreme iPhone case

I backed a rugged, heavyset and multifunction iPhone case on Kickstarter, before but when the design of the iPhone 4 and 5 was still in question, I chickened out of one waterproof case, but later backed another. More rugged, more functional, and more feature packed, I was relieved to see another project offered, and I had the gumption to back it, and then I had to wait.

This was the case that I backed. Billed as the Aqua Tek S on Kickstarter, and produced by Snowlizard. When it was ready for release it was renamed by popular backer vote, to the SLXtreme. Offered in a variety of colour options, I opted for the coyote-tan, surprise, surprise.

The basis of the case is that it fully encloses the iPhone 4/4s in a water, dust and shockproof polycarbonate shell, whilst still leaving the majority of functionality available to the user. During the design and manufacture process, the forward and back facing cameras, and flash, volume up and down buttons, and the main home and power buttons are all accessible whilst in the case.

 It turned out that the mute/orientation slider and earphone ports were too difficult or impractical to accommodate.


The multitouch screen, mic and speakers are faced by a thin polymer membrane which alternately allows the electrostatic use of the iPhone screen and transmission of sound from the speakers, and to the mic. I was skeptical to start with, but was pleasantly surprised both by the crispness of the control surface (no real difference than any other screen protector) and of the sound, (slightly muffled, but perfectly acceptable sacrifice for the protection offered when adventuring).

The base of the case has an access port for charging and synching the device by micro USB, with the 32pin iDevice plug being built into the insides of the case, the port being protected by a sealed flap, which is secured shut with a thumb screw. Also held in the front base of the case are a set of blue LED battery charge indicators.

The top of the case latches open and closed to accept the phone, which sits very snugly, as it is built with low tolerances, and even complying with IP68 & Mil Spec 810, but not so snug as to be impossible to take the phone in and out, even with the screen protector I have on it.

The latch has a slide lock, to help resist those "unexpected underwater openings"

The two camera ports are equally well designed, and don't significantly degrade the picture quality,

All the buttons could be described as "stiff" and the inlay to get to the edge of the multitouch display is pretty tight, but I'd rather a little awkwardness over a busted screen or waterlogged phone any day. The stiffness of the buttons only goes to reassure me that they won't break, or be a source of failure and ingress.

The case is large, it's bulky. It is very reminiscent of the old brick phones around when mobiles broke into wide circulation. This however, is not a big concern for me, given the nature of the protection offered and the additional features built in.

As well as being rated to 2m submersion, mud, dust, sand and rain proof, shock resistant and generally ruggedized, this case also packs a built in lithium ion polymer battery, providing DC 5V - 1A with 2000mAh capacity, giving an impressive boost to the standby (380-hrs), talk time (7hrs 3G, 17 on 2G), internet usage (7hrs 3G, 10hrs on WiFi) and 46 hrs audio, or 11 hrs video play.

However, the SLXtreme goes one step further in that it's back face has a built in solar panel, capable of generating 10 minutes of talk time for an hour of sunlight. This may not sound like a lot, but in a survival situation, it is plenty of power to send text messages, power up the GPS features of the iPhone, read up instruction manuals and yes, make calls as needed.

I have a lot of navigation, mapping, surveying and "guide" apps on my phone, and for the times when I am off-grid, but still want access to my data, and the stored knowledge, knowing that I have a near infinite supply of charging power, is very reassuring.


The Snow Lizard team took a lot of flak over the delays in production, from the initial Kickstarter which was successful in March 2012, till when I received mine in November 2012, and the iPhone 5 coming out in the interim. I really feel for them, but had no such concerns. Kickstarting isn't an exact science, and I'm just glad I got a product.


I am happy with my "less than newest" model of phone, and the accessories I have for it.

The case is rugged, light (at 317g including the 4s, making it a tad under 200g of battery, solar charger, water, crud and shock proofing that I can take into the field with me, do the Stampede or Tough Mudder wearing, or whatever.

Not being able to plug my headphones into it is a drawback I am willing to live with, for what I get, and I look forwards to Snow Lizard to come up wit hthe PALS/MOLLE attachment they posted mock-ups of. Till them, its off to Platatac to ask the lads what they can do with me to include this case in my loadout.
