Finally, a portable battery designed for the MacBook

view-side

What if you had a Mophie-like battery pack for your MacBook? Available for preorder now, the BatteryBox is exactly that.

The box itself is about the length of a credit card and packs a whopping 12,000mAh battery. That equates to about 12 hours of extra juice for the MacBook Air and 6 hours for the Pro. The BatteryBox can charge any device over USB, and it has its own MagSafe2 connector.

The technology behind it is called BatteryOS, an anti-degredation power management system that promises to keep the BatteryBox working at 96% capacity after five years.

When connected to a MacBook, BatteryBox bypasses the laptop’s actual battery and instead feeds power directly to the system. The approach is designed to minimize strain on the MacBook’s internal battery.

The BatteryBox is charged via MicroUSB, and it takes about nine hours to reach a full capacity.

You can preorder your own BatteryBox on the product’s website for $129, with shipments scheduled to go out this fall.
