Can charge with mini usb cable (not included) if there is no sun. You can plug the mini usb cable into a pc, laptop or usb wall charger to charge it.
I will write more when the weather gets nicer and I have tried the solar panel out!
It charges my iPhone 4S super fast!
I know I will get so so so much use out of this awesome high quality device!
Is made of high quality material (aluminum alloy case), this is not made of plastic! Awesome!
I knew the apple connecter it comes with might be too fat to fit into my Otterbox ARMOR case so I ordered an extra iPhone charge and sync cable from this site as well to use with the battery. Glad I did, because indeed the one it comes with is rather fat and bulky, probably the biggest end on an apple 30 pin charge and sync male plug I have seen, but who cares, this thing is awesome and this wasn't even a concern for me.
Love this thing, will defiantly recommend to all my friends and family!
Just make sure you understand customs and import taxes for importing items into your country, but even if you have to pay a little more for taxes and import duties, still worth it at the great price I paid.
Regarding about what I'm about to say, this is approximate, every order is different, take it with a grain of sand. I live in Alberta, Canada. My order of three electronic items came to about $57 Canadian total, when they came to the door the bill for taxes and duty for this whole order of three electronic items all together was an extra $18 in addition to what I paid mini in the box. Seems like a lot, but they have really good prices and the product is really good, it's not cheap, will last me a long time!
