DJI Osmo Multifunctional Battery Case 3

The case itself does not have a stored capacity; it charges and holds up to three Osmo Action batteries. It can then use the power from these batteries to charge other devices.

A USB-C power adapter with Power Delivery (PD) is recommended for optimal fast-charging speeds. The adapter should have a suitable wattage output as per DJI's recommendations for Osmo Action batteries.

No, the case primarily charges its internal batteries or uses them to charge external devices. When charging its internal batteries, it cannot simultaneously output power to other devices.

The case can store up to two microSD cards.

The product information does not specify waterproof capabilities. It is designed for protection against dust and minor impacts during transport and use, but should be protected from water.

Warranty information is typically provided by the retailer at the time of purchase or can be found on the official DJI website. Please refer to DJI's official support channels for detailed warranty terms.

Ensure the USB-C cable is securely connected to both the case and a functioning power adapter. Verify the power adapter is providing sufficient power output.

Confirm that there are charged batteries inserted into the case. Ensure the USB-A output port is clean and free of obstructions. Try a different charging cable for your device.

Ensure you are using standard microSD card sizes. Gently insert the cards straight into the slots. Do not force them.
