Crafted for freedom from the outlet

Power outlets can be a hassle to find. BatteryBox is built to be as portable and powerful as possible, giving you the freedom to use your gadgets anywhere - no matter how remote.

Smart battery technology that improves itself and your MacBook

Users of portable consumer electronics have just come to accept that battery life gets worse over time. But it doesn't have to. BatteryBox is built with the first commercially-availiable new battery technology - BatteryOS. It lasts 3000 cycles, prolongs your MacBook battery health, and improves itself as you use it.

Maintains your MacBook battery health

BatteryBox powers your laptop rather than charging it, keeping the battery at the same charge percentage.

By bypassing the MacBooks built-in battery, BatteryBox minimizes the number of cycles (and stress) on the internal battery, prolonging it's life.

3x longer life than any other battery

The batteries in BatteryBox keep working like brand new even after many years, thanks to patent-pending BatteryOS technology. provides better performance without battery-life degradation. Feel like geeking out?

The worlds first battery testing platform

Battery advancements have traditionally taken long to evolve, and while everything in electronics seems to be getting better and smaller every year, batteries don't.

We're changing that with BatteryOS, and are fueling that change by gathering in-depth battery diagnostic data from each BatteryBox. By using BatteryBox, you're contributing to the first and largest battery data gathering research of it's kind - creating a new battery that works longer, lives longer, and charges faster.
