With up to 60 hours of non-stop music, the Energizer ER-i50 is the ultimate rechargeable lithium ion battery pack for the Apple iPod. Compatible with the 3G, 4G, mini, photo, and U2 versions of the iPod, youll have enough battery life to last even the longest of trips.

The ER-i50 includes a protective neoprene and PVC case that conforms to the specific version of your iPod to protect from dirt, dust, and smudges while the built in belt clip lets you decide how you want to transport your music. With the ER-i50, you dont have to worry about carrying any additional cables as you can connect the battery to the iPod via the Apple FirewireTM cable and recharge using the Apple FirewireTM AC adapter.
