Essentially a backup battery on serious steroids, BatteryBox is a compact way to ensure your devices keep on running when accessing an outlet is impractical. This 60Wh battery pack stashes enough juice to extend your MacBook Air’s life by 13 hours, fully charge your iPhone 11 times over, and adds ample longevity to any other USB-powered modern device. It’s also made to last thanks to the BatteryOS energy controller, which ensures 3,000 recharge cycles before significant battery deterioration sets in, meaning BatteryBox will be by your side far longer than conventional options.
