Pau Hana Daz I bought a Suntactics solar charger back in 2010 and have never regretted it. It's a charger only - no battery. It's only 1 amp (5vdc) via USB and it charges my small electronics (iPod, Kindle, smart phone) at about the same speed as using their respective AC cords, and, since it has a USB plug, it works for all three. I've never gotten mine wet, but it advertised as being waterproof.

hellosailor Those packages are nice integrations, but, for instance, that one contains a lithium battery equal to two $25 "usb recharger" batteries, plus a tiny solar panel. Well...another $50 would buy you a lot more panel than that. Which of course wouldn't fit in your pocket.

But if you are going off-grid, don't plan to use a lot of power, but want a long-term way of topping it up IF you do...they probably would work well. Personally I just picked up a couple of the usb batteries on sale, I figure they'll give me a boost long enough to get me back to the grid, if I need one. There's also a little hand-crank gizmo for the same purpose, not expensive.

n0w0rries Thanks all for the feedback. I've seen a few interesting looking devices on Amazon that have a solar charger and battery built in.
Example:

Anyhow, sounds like they're not quite up to the task yet.

Converting DC to AC to DC is very inefficient and unnecessary in most cases. Just use a cigarette lighter adapter. There is no need to use an inverter for the devices that you have listed.
Yep! That's true. All the above listed devices usually come with small, DC adapters for charging and operating the device. I just didn't think about that until you mentioned it. (Guess my mind's starting to go--my wife said it was the second thing! )

travlineasy A DC to AC inverter, something about 100-watts, will do everything you want, plus run a 20-inch flat-screen TV at the same time. The drain to your house batteries will be approximately 1.2 amps per hour if the inverter is loaded to maximum.

Cheers,

Shark0311 I would recommend a Powerfilm 10w (Link) or 20w panel with a small charge controller for your on board battery or a Brunton Resync. The key to using solar is to have intermediate power storage.

Thanks, I'll buy eight batteries for the same $200 and get eight times the recharging for the buck. I know, I'll have to find power someplace after that, but you'll have to find new cartridges and I'll bet those won't be at the local bait shop, either.
I know, it was a joke. You know... sarcasm.

PowerTrekk fuel cell charger allows for power on the go


Outdoor types who need power for mobile devices away from the grid may find themselves carrying solar chargers or battery packs but, as we reported last year, hydrogen fuel cells offer instant juice benefits and zero degradation. Now, Stockholm's myFC and SiGNa Chemistry have teamed up to launch the PowerTrekk, a pocket-sized, portable charging solution that combines the convenience of a battery pack with the instant power of a hydrogen fuel cell.

Developed to provide some off-the-grid juice to outdoor enthusiasts or anyone who finds themselves away from a wall socket when their smartphone, GPS or digital camera battery dies, myFC's PowerTrekk 2-in-1 portable charger is the first to use Mobile-H2 technology from SiGNa Chemistry. In addition to sporting a Li-ion battery pack, the device also takes a Mobile-H2 cartridge called a PowerPukk.

The PowerPukk disc contains sodium silicide (NaSi), a non-flammable powder which rapidly produces hydrogen thanks to a stable and controllable reaction with a wide variety of non-potable, non-distilled water – including salt water – at room temperature. SiGNa says that the powder is generated from salt (sodium chloride) and sand (silicon dioxide) starting materials in a solvent- and purification-free process where the heat generated during manufacture is recaptured and used within the process, keeping energy consumption down.

About a tablespoon of water is added to the central well of the PowerPukk after it's placed inside the belly of the PowerTrekk, after which the device's Proton Exchange Membrane starts to silently convert the hydrogen into electricity. The only by-product of the process is a little water vapor. There's no more waiting around for the sun to harvest enough energy to power your gadgets, and the unit is said not to suffer from degradation often associated with battery packs.

The PowerTrekk's built-in Li-ion battery buffer has a capacity of 5.9 Wh (1600 mAh, 3.7 V) and the device has a rated output of 5V, 1000 mA and rated input of 5V, 500 mA. The PowerPukk Fuel Cartridge can be swapped out without interrupting the supply of power to the attached mobile device.

One cartridge is said to provide the device with enough power to fully charge a smartphone's battery, but myFC says that "if the internal battery/buffer is full it will charge more than 2 smartphones or 15 iPods."

PowerPukk cartridges come in either five or ten packs and have a shelf life of two years minimum. myFC told Gizmag that an end of operational life recycling program to best fit consumers would be launched when the PowerTrekk and PowerPukk discs go on sale.

The 2.59 x 5 x 1.65-inch (66 x 128 x 42mm) PowerTrekk, which is currently on display at Mobile World Congress 2011 in Barcelona, will come in green, red or yellow and is expected to be shipped internationally in October for an estimated US$200. PowerPukk discs will likely cost of couple of dollars each.
