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.

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.

Thanks all for the feedback. I've seen a few interesting looking devices on Amazon that have a solar charger and battery built in.
Anyhow, sounds like they're not quite up to the task yet.

FYI most devices that charge via USB cable charge at 5 watts (5V @ 1A). The exception is the Ipad that charges at 10 watts (5v @ 2A).
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.

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.

|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.|

A $200 gizmo that requires cartridge$ and still only produces the same amount of power that is stored in a cellphone (external) battery. Which costs $25 on the street and can be recharged 500 times.
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.

Get yourself one of these bad boys.
