Ever used a bunch of devices while on the go, only to realize that you forgot to recharge your cellphone the night before, and there is no power point in sight for the next 4 hours as you're in the middle of nowhere? Enter the ReCharge4 smart battery which can be recharged. This handy device enables you to recharge your portable device anytime, anywhere, up to 4 times from a single charge. There are 3 different versions - the cellphone version, the game device version, and the music player version. Needless to say, all three versions are pretty much self-explanatory, and we think that the game device version will be able to offer your PSP and Nintendo DS a new lease of life. Road warriors should pick up the ReCharge4 rechargeable smart battery before the head off to their next destination as you never know when you might need extra batteries. There is even a display which tells you how much charge there is left. Pricing details are currently unavailable.

Pros : Recharges a variety of devices up to 4 times with a single charge
Cons : None
