iPhone Battery Review:
I love being able to toss this in my bag and not worry about my phone dying at work when I'm unable to plug it in. Also when i went camping it was great since I charged it and the phone, which left menwith a nice backup. My daughter has used in on a long trip to recharge her iPod and it saved my sanity.

I am using it with an iPod Classic. I let the iPod battery run down almost completely, then plugged in the battery/charger. I then watched three movies in a row (I'm talkin' serious eye strain here!). Video drains the iPod battery pretty quickly so I was somewhat surprised that the battery/charger could supply 6+ hours of video, and even more surprised when I uncoupled it and found that it had not only powered 6 hours of video, but given the iPod battery a full charge as well---and the indicator lights on the battery/charger showed it still had 3/4 of its own charge left! No instructions included with the unit, but it is pretty easy to figure out. It charges from the same USB cord used to charge the iPod.

Got this for a long plane trip to use with my iPod Touch 2G. Works great, good mAh rating for the money, compact size. Have used it fewer than 10 times so far. I can use the iPod while the battery is plugged in; the connection feels a touch loose but it's about the same feel as other OEM docks that I plug the iPod into.
