Solar powered battery chargers?

---

I see this solar powered battery charger on dealextreme, but are there any other better options? Like waterproof or made more specifically for our IncS with micro-usb.

i dont use it as my daily driver.. just in case of emergency.. but it charges pretty fast and it charges till 40-50%... right now its kept in some corner... but i charge it through usb rarely use solar...

all the solar chargers i found so far only charge with an output of 80mAh, so once the battery pack is empty its actually useless.

i think its better to buy a batterypack without the solar charger because it wont be much help.

I think solar charger cannot give enough voltage for phone. I think it just an option to make your phone battery not drain out.

just buy one of those powerbanks, relatively cheap and charge as fast as a wall adapter.

i dont think the solar charger is necessery for common user

Voltage isn't the issue. You'd just use a boost converter to bump it up to 5V. Every battery pack like the powerbank and similar includes such a circuit, as they either use a 3.7V li-ion (or li-poly, or similar) or a pair of alkalines (1.5Vx2).

The issue is getting enough current to charge something meaningfully.
