The GNARBOX 2.0 Battery is a rechargeable lithium polymer battery for the GNARBOX 2.0 SSD. This battery (3000mAh / 7.6V / 22.8Wh) delivers power for up to 3 hours of continuous photo and video use, and up to 6 hours of continuous backups. When the battery dies, it can be recharged in the GNARBOX 2.0 SSD or the GNARBOX 2.0 Dual Battery Charger. The battery takes about two hours to recharge when using the USB Type-C to Type-C cable and the 35W / 2.1A power adapter, which are included with the GNARBOX 2.0 SSD. Having multiple batteries allows you to swap them while using your GNARBOX 2.0 SSD, which eliminates interruptions while in use.
