Energizer, a household name when it comes to batteries, has teamed up with XPAL Power to further expand its Energi to Go line of portable battery packs. These new chargers are virtually compatible with every popular device in the market these days, ranging from an iPhone 3GS to solar chargers or even the larger lithium ion charger that can provide enough juice for up to a trio of devices simultaneously, including a notebook. These XPAL-branded packaging will hit retail stores pretty soon, with a trusted name to back it up behind the scenes.
