Crafted for those who are always on-the-go

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.

3x longer life than any other battery

The batteries in BatteryBox keep working like brand new even after many years, thanks to BatteryOS technology. Feel like geeking out? Learn more about BatteryOS >

Designed to maintain your battery's health

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

By bypassing your laptop's built-in battery, BatteryBox optimizes its efficiency and allows for more energy to flow into the laptop - adding on even more time to your freedom from the outlet.
