The energizer bunny has been a busy bunny! The launch of energizer rapid mobile phone charging devices know as Energi To Go (how do they think of these things) will bring welcome relief to mobile phone users and gamers on the  move.

Two packs will be available featuring two and four batteries and will allow users to place a call from a flat mobile phone in just 30 seconds of charging. The Energi To Go can already power up to 80 percent of mobile phone brands with tip connectors for 100 mobile phone models from leading manufacturers.

The good news is the device will be compatible with iPods, Sony PSP, Nintendo DS and Game Boy Advanced consoles. Priced around £19, the Energi To Go should be available soon.
