Energizer has released a portable travel kit that finally works with your iPod Touch or iPhone; and after testing it out we can say it is extremely handy. To charge the actual batter pack you can either use an AC wall outlet or fix on the DC attachment for your automobile.
This kit also charges phones via their micro and mini USB ports. The “energi to go” battery pack will give around 14 hours of extra talk time on your device and should give you enough time to find a power outlet to charge up your device. Another useful feature is a LED indicator built-in to let its user know when the external pack is almost out of juice.
