It can store and charge batteries. When used with the DJI 65W Portable Charger, it can fully charge three Intelligent Flight Batteries simultaneously in just 60 minutes. With at least one battery stored, it can serve as a power bank, using the remaining battery power to charge devices such as goggles or smartphones.

The number of batteries that can be charged simultaneously depends on the power of the charger used. Using a charger of more than 45 W allows for charging three batteries at once while using a charger of less than 45 W can only charge two batteries simultaneously. Refer to the charging protocols supported by the charger.
