Imagine a situation - you’re camping out, or you’re on a beach (regardless of where you are and if you’re there on your free will). The thing they have in common is no electricity. And then you see that the battery on your phone is runing low. What do you do? Most likely you think (hope) that it will last until you find a place with electricity and recharge it.

Umm…yeah. That has worked when? It’s a well known fact of the universe that in these cases cellphones eat energy faster and they are drained in 15 minutes. So you have the options to find an outlet and recharge your phone (hope you remembered the charger) or recharge it in a mall or somewhere where they offer recharging (but do think that you’re not the only one with a phone like that, and you’re not the only one unprepared, so get ready for a long line).

However, you do have the option of being prepared. A slim little black box, that fits easily in your pocket (8cm long), flips open and reveals two solar panels.You know what’s coming next, right? - it’s a solar powered mobile phone charger. Comes with adapters for Nokia, Siemens, Motorola, Samsung and Sony Ericsson mobiles.
