Doing the Sydney-London run? Then it might be a good time to catch up on the last season of Monk on your video iPod -- oh, except that it'll conk out in the middle of the fifth episode, leaving you with the rest of the flight to contemplate the fine selection of in-flight movies.
For those marathon movie/music sessions, Newer Technology has just released the US$49 NuPower Video+, a slim lithium-polymer battery pack that clips into place on the back of a fifth-generation iPod. You can also use it as a portable charger, and a charging cable port in the back means you don't have to detach the unit if you don't want to.
The base of the Video+ also doubles as a stand, but to all appearances it seems that the iPod is held kept pretty much vertical, which isn't much use for viewing unless you're crouching in front of the surface it's on. In any case, Newer Technology says that a three-hour charge on the Video+ supplies up to 16 hours of video or 80 hours of music, so unless you opted for the three-hour stopover in Hong Kong, you're pretty much covered.
