    Works if you know it's limits.

    First of all I think people must be made aware that an iPad has approximately a 11,600 mah battery and iPhones have approximately 1440 mah batteries, while the mophie has a 6,000 mah battery. Also, battery to battery transfer of energy works best when the charging battery is lowest and gets worse as the charging battery fills up. So at most you're getting 50% charge out of an iPad and 4 charges on an iPhone. However that assumes 100% transfer which you can't get. If you want this to work best wait till your device is about 20% battery and plug it in for an hour. That should get you to about 80% + and you can do it about 7 times. If you try to go from dead to full you might get about 3 maybe 3.5 times. If you know the capacities and have realistic expectations this works great.

    Works great as advertised!FYI READ INSTRUCTIONS PEOPLE.. It clearly says it will not fully charge new ipad! It will charge it from dead to about 60 -70 percent and it will charge any iphones at least twice to full so overall a great product i would say...

    Extremely handy external battery while on-the-go

    • Written by from Waterloo

    A superb external battery for the iPhone and iPad. Charges at 2.1 A, so it's as fast as an iPad wall charger. The casing is metallic and rubber and looks expensive and sleek. It can charge two devices at the same time, and has a few lights to show the remaining charge. It's a bit bulky but fits easily into a bike saddle bag or something similar. The capacity is 6000 mAh (the highest sold by Mophie) so it should be able to charge an iPhone 3 or 4 times, and that's consistent with my experience. However, the phone needs to be in sleep mode during charging or else it'll eat up the battery capacity a lot quicker. Does not support pass-through mode. Also offered in a ruggedized waterproof version from Mophie directly, although this one tolerates splash damage.
