Now this is an amazing product, there have a been alot of different companies providing alternate battery power sources for different products but none as thorough as the HyperMac for Apple Laptops & iPads. Giving you from 19-34 Hours for the MacBook Pros, and 30 to 92 Hours for the iPad. Thats a lot of hours, and pretty damn good in my opinion. Thats just a ridiculous amount of power that you can use while traveling or in the car, on a train, or stuck in a airport for a really long time. Prices range from $200 up to $500, which isn’t cheap but its a very solid product for a specific purpose.
