A dual charger and a typical 1600mAh battery are included in the GoPro Dual Battery Charger with Enduro Battery bundle to power your GoPro MAX camera. The charger works with standard or Enduro batteries for the MAX camera and supports charging one or two batteries sequentially. In order to give you a fully charged battery as soon as possible, it charges the battery with the greatest remaining runtime first. Each battery’s charging status is confirmed by a separate LED indicator.
