2400mAh Solar Powered Rechargeable External Battery with USB Data Cable for iPhone 4

Pros: Recharging from both the electrics, so the solar panel. Excellent is the charge indicator on the front of the charger. Very easy to use, easier to control it or not.

Cons: This charger is big enough, never mind the length and width, but it matters that it is thicker than the iPhone, I would say that up to one half. It could be a cover bottom, to the charger could not get the dirt.

Other: Excellent backup energy source not only for the iPhone on the go, but wherever there is electricity. Very nice treatment from both sides. I think it's a great tool for any iPhone, everyone I highly recommend this purchase.

Pros: Compact.
High capacity battery
Solar Cell or plug in charging
Nice cable included

Cons: The solar cell is mounted a bit loosely and it doesn't look to be the best quality cell but what do you expect for such a low price.

Other: Really inexpensive solution to mobile power for iPhones and iPods.

Pros: Light weight, fast charger very helpfull. The charge inside is kept for a long time so you can use it on the go even if you will need it like a week ahed last charge (plugged in the eletricity).

Cons: The solar charge doesn´t work as I thought, you have to wait a lot even on noon sunlight. The connector is too fragile, so be careful.

Other: Go ahead and try, you will not be disappointed!

Pros: -charges to 100% -good plastic quality -charges from sun lights, even if it's not located direct under the sun -has a chargle level indicator -very light

Cons: -not so good quality of the connector

Other: very usefull thing, u can connect, and continune using the phone, talking is more comfortable then charging with the charger. It's very good for presenting to friends, already presented one to my girlfriend

Pros: Size, capacity, ease of use, fast input and output of power, never without my mobile phone again, low price considering similar devices, very nice design, power indicator with 4 nice blue LED lights

Cons: Nothing really, maybe it is its weak constitution (connector looks like it could be aesily broken) and slow charging in sunlight but maybe it will be better in summer (now is november)

Other: Very useful product which I`ll use many times on my cycling and hiking trips

Pros: Never used things like this but it actually charges your iPhone pretty fast if you're on the go. It takes alot of sunlight and it charges it like immediatly to your iPhone, no small generator or something. You can charge it in the sun when not charging iPhone aswell, thats really great.

Cons: If you're using a case (like I do, the sillicone hardened case) it does not fit in to the connector because of that small black verge at the top of the charger.

Other: Great charger, hard to use with an case.

Pros: Can't be easier to use. Automatic charging when in contact to decent sun. Connect it directly to your iPhone/iPod/iPad and nothing more. The included USB is practical to charge the battery when very little to no sunny days.

Cons: Although the indicator says it's fully charged, it doesn't hold a full charge. solar panel is not very sensitive. No light bulbs can charge the battery. Cable is tricky to connect. Doesn't fit well on the idevice and the battery charger.

Other: This is a very practical way to recharge your iDevice when you don't have available an electric outlet and you are traveling on sunny days. Highly recommended.

Pros: This is one the best portable chargers for the iphone available in the market. I had earlier bought a portable charger from another site, which never worked. So hesitatingly, I bought this one. Fortunately, this one not only works perfectly but also has a solar panel included as an added benefit. For me, it gives up to two full charge cycles before needing a recharge.

Cons: The solar charging is a bit slow, but at least it works.

Other: Go for it !

Pros: Very good, it can charge iPhone both way (solar and electric). Can charge the phone while you are charging the buttery (both way). It can fully charge phone twice with one buttery refill. Solar charging works even 1 m far from window.

Cons: Weak and very thin connection pin to iPhone, but overall it is good when you put the phone into the desk and it is not moving. Solar charge is a little bit slower.

Other: In sunny days I always use solar charge, save money.
