Your MacBook is power hungry. At home or in the office, it’s easy to plug in and feed the MacBook some power. On the road, it’s not that easy—until now.

Powrbloc can use readily available batteries like V-Mount batteries, Anton Bauer batteries and the cigarette lighter socket in your car. Unlike most battery power adapters, Powrbloc can feed the MacBook Pro the 87 watts of power that it craves.

Powrbloc comes in two styles: Catalyst and Injector. The Catalyst has a full size V-Mount or Anton Bauer Gold Mount battery plate and the Injector is a smaller version that can plug into different power sources.

If you are not from the commercial photo or motion picture world, you may not be familiar with V-Mount or Anton Bauer batteries or P-Tap (Power Tap) power sources. V-Mount and Anton Bauer batteries can bought and rented in just about every city in America. V-Mount are even more common overseas. They come in all kinds of capacities from 50Wh to 300Wh or more. If you need a bunch for a project, it may be more economical to rent them. If you want a couple of your own, here's some links to some V-Mount and Anton Bauer mount batteries:
