Video Review: HyperMac 150W External Battery

Rating: 9.5 out of 10
Pros: Extends battery life on MacBooks up to 21 hrs. Can charge the iPhone up to 35x without recharging. Very accurate battery indicator lights.
Cons: Battery’s power brick can get very hot. Does not get fully charged if you are trying to charge both the battery and a computer off of the battery at the same time. Replacement MagSafe cable costs $100.
Overall: The Hypermac, though pricey, offers a lot of bang for your buck. With three of the four batteries they sell coming with the DC Charger, normally sold for $150, a battery that lasts 21 hours, and an extra charger for your laptop laying around it is a great buy that you won’t regret.
