everything perfect would highly recommend this product and seller and excellent dilvery time.

Everything works. Charges as a full charge, can charge 2 phones. Even if the sun rays do not fall directly, the phone charges. From a bright bulb does not charge, but from a bright candle I do not know yet, I'm interesting. You can put in a backpack. The order is executed quickly. About the waterproof and resistance to heat has not yet checked

I tried to charge the phone on the window in the apartment. If there is a sun, then the norms are charged. If the sky cloud phone shows that to empt an external power supply.

I deliver fast

excellent
