Hello folks, I am flying on long distance flights for next couple of months and would like my 2G iPod touch to have enough juice to play the movies. There are many battery packs available but rather than getting a new battery pack, I liked this AA battery charger. Since I have a lot of rechargeable 2500mAh AA batteries lying around, this would be a very good one, if it really works. Is anyone here using this? I wonder how long one set of 4 2500mAh batteries would last with 2G iPod touch if this gadget works well? Thanks in advance.
