One of the leading battery makers in the world, Energizer has collaborated with XPAL Power to take its ‘Energi to Go’ battery packs to an all new level. The new line of battery packs charge a variety of portable devices including laptops.
This all new line includes Apple iPhone 3G/3GS charger, solar chargers and even lithium ion chargers that are capable of charging notebooks and laptop computers.

Almost every Energizer portable battery charger pack comes with a long list of mobile phone tips for various makes and models. This list will constantly be updated on the Energizer and XPAL Power websites, with the launch of new cell phone models.

Nice review. The Energizer 15 Minute Battery Charger may work pretty okay however you cold expect diminished performance over time from the batteries if used in high-drain devices. Hopefully, competition will eventually deliver some truly high performance rechargeable cells.
