zeil-
"keep the one that performs best"
The technology behind them is all about the same. All solar cells are fairly similar in performance. All the consumer really needs to know is what is the power output of the gizmo, what is the storage onboard (if any) and then do the math. Compare reviews (on Amazon or other sources) to see if one is poorly made or not, but take the reviews with a grain of salt because a lot of the reviewers don't understand basic concepts. Which is why Apple won't let them change an iPhone battery without adult supervision.

Re: Solar phone/tablet chargers

Thanks everyone for your thoughts. It looks like some more research is in order; unfortunately, these chargers are not so cheap that you'd go buy a bunch, test them, and keep the one that performs best (I suppose that's what CNET and Wired are for).

got solar/wind on the boat But the admiral got a littlefolding 2 panel from REI that fits in purse/pocket and keeps us going in a pinch. she's had it for 3y now and it still works. one I got thro internet broke in a ~week. moral- if you're going to carry it around make sure it's durable.

Re: Solar phone/tablet chargers

The marine 12v sockets destroyed my verizon cell phone charger nor would it allow me to use the regular 12v usb plug. If you have a 12v on board you should at least have one automotive one that doesnt have the lock ring on it. On that trip on a friends boat out of refit there were 5 people with no way to recharge since there were no inverters and the generator failed. I went and got a little 30 dollar solar charger/battery on amazon. It works great though it likes to use its on cables for charging.

Modern Lithium batteries do not suffer the same "memory" problems of older technologies.

I don't understand why you don't just plug the phone into your 12v system. Your house battery has the capability of charging your phone many dozens of times.

Re: Solar phone/tablet chargers

I love my iPhone. And I don't say that about many things. I've started my trip a couple weeks ago so I can give you some advice.

First off I would turn your phone on airplane mode when you aren't using it. A lot of what drains the battery is the constant searching for a signal. When not in use I get double or triple the battery life if I do this. Or tub it off completely but I think that's unnessary.

I got a rollable small solar panel for the boat and its mainly to keep my boat battery charged to charge my phone. It works through a cigarette plug adapter like mentioned above. I've got to think that's the best way. I can't see a smaller solar panel working and if it did you would spend all day charging. And eventually you would lose it damage your phone or tablet.

Solar phone/tablet chargers

I researched and bought a Joos Orange. It holds four recharges for my iPhone, has good build quality, and made me happy.

Re: Solar phone/tablet chargers

Here is a review that Wired did a year ago on four:
Sun on the Run: 4 Portable Solar Chargers Tested | Product Reviews | Wired.com

BUT, a newer one that I have heard good things about (haven't used it myself) is the Goal Zeron Nomad series: Portable Solar Battery Charger | Portable Solar Panels | Off-Grid Solar Generators | Goal Zero - Extreme Portable Power

Whatever you find, I would go to Amazon/CNET/wherever and read reviews to see what people are actually getting out of each one.
