Is it possible to record a long session, while charging Osmo Pocket from external source.
Thanks.

There is a facts section on the Osmo Pocket by Dji that says you can charge while in use even with a phone connected to the other socket. So in theory with an external power pack, you could charge your pocket which in turn will charge your phone.

Hello and good day adamw. Thank you for the inquiry. Yes, you can use/record using the DJI Osmo Pocket while charging the unit. But, it is recommended to charge the unit fully before using it as the battery life might be affected by the heat, please kindly note and understand.

What capacity of charging pack would you suggest to purchase.
Many thanks for your replay.
