HyperMac already has a great range of MacBook battery juicers which can power your Apple laptop for up to 34 hours through an adapter attached to your default Apple power brick, but now they are getting into the iPad game with a range of batteries featuring 10 Watt USB ports that can power your tablet for more than four days.
Buy the most expensive HyperMac — a four-and-a-half pound, 222 watt hour monster battery costing $500 — and you’ll get up to 99 extra hours of battery life from your iPad. Of course, that battery costs about as much as the iPad itself, but for just $169 $200, you can get a smaller 60 watt hour battery that will still keep you going for another 34 hours.
