If you don't love it, we'll take it back and give you a full refund - no questions asked.
Meet BatteryBox. It's a portable battery that works for 3000 cycles and can power a MacBook Air for 13 hours straight, or fully charge an iPhone 11 times.
BatteryBox includes a special cable for powering MacBooks, and a USB port for charging phones, tablets, and anything else. Extra 60Wh of charge for your MacBook, with a USB port built in.
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.
The batteries in BatteryBox keep working like brand new even after many years, thanks to patent-pending BatteryOS artificial intelligence. This technology provides better performance without battery-life degradation.
