HyperMac External MacBook Battery Review

The Gadget: The HyperMac external laptop batteries, which, through its Magsafe connection gives MacBook Airs up to 32 hours and MacBook Pros up to 8 extra hours of battery life. In our test, the 222Wh was able to sustain a MacBook Pro at full charge for eight straight hours. It takes 3.7 hours to charge the HyperMac to full, and you can even continue powering your laptop while this charges, giving you an extra MagSafe charger at home. One very sneaky use for this is taking the battery to work and filling it up with your company's power, then taking it home and powering your laptop(s) and USB devices off of this. And with the new built-in battery for the MacBook Pros, we're going to be stocking up on these instead of extra internal batteries.
