Having to buy batteries stinks, but at least Energizer is starting to cater to gadget-lovers. After a positive response with its cellphone chargers, Energizer has released the Energi To Go Portable Power For iPod. The device runs off of two Energizer e2 Lithium AA batteries, which provides up to 32 additional hours of music.
Energizer will sell tons of these to people with dead iPods, especially at airports. For only $30, it might be worth picking one up for long flights or car rides.
