BatteryBox • BatteryBox

Extra battery from a better battery,
for all your electronics

We created a smart portable battery that powers MacBooks and USB devices while improving itself and your laptop. BatteryBox is integrated with the worlds first battery artificial intelligence - BatteryOS^TM - enabling impressively high performance without battery-life degradation.

HEALTHY BATTERY

BatteryBox powers your laptop rather than charging it, keeping the battery at the same charge percentage - minimizing the number of cycles and stress on your MacBook. This way you get the most power out of BatteryBox without wasting any energy from it travelling through the MacBook battery first.
