They claim that their 50 Whr battery can power a MacBook Pro for 6 hours, a MacBook Air for 12 hrs. By my math, that would mean that the MacBook Pro would only be consuming an average of around 8.3 watts an hour, the air only around 4.2 watts an hour.
That seems absurd to me, considering the power supplies that ship with the MacBook Pro and the MacBook Air are 85-watt and 45-watt respectively. They are assuming that each only draws about 10% of the power that the official power supplies are rated at. Anyone have a Kill-A-Watt to see the actual draw of their device?
