The Sanho Hypermac is their latest external battery pack designed to provide a MacBook Pro with up to 32 hours of straight run time.

With a price tag of about $500, this 222 Wh battery supply really isn’t designed for mainstream everyday use but rather would be something where businesses or perhaps hospitals that run critical applications need an external battery supply to sustain them through long power outages.

The company has also released a couple of other more economical devices including a $150 car charger as well as a $200 60Wh model.
