iGo powerXtender Battery Operated Charger
Expansys have just started selling the IGO PowerXtender Battery charger. I use all the IGO chargers for mobile devices and also my laptop. Why... well I can carry just one charger and charge all my devices from one unit!
With this battery operated charger you can use the same tips for charging your devices from 4 x AA batteries!
You can buy it from Expansys from HERE
