Sanho’s Hypermac amounts to little more than a large external battery pack. Sure, it’s a great idea. And who wouldn’t want that kind of performance from a battery? We’re talking 32 hours here. That’s more than a full day.

But seriously, most of us have an outlet handy which is far less painful than dropping $500 on this 222Wh unit. But if this appeals to your need for power, it ships later this month. But ask yourself this. Do you even use your MacBook for 32 hours straight? Have you ever?
