I'll be traveling and wondering if I can charge the drone using a powerbank? What is the power requirement?

Hi him7403, thank you for reaching out. Yes, it is supported with powerbank of 5V/2A output. However, the output might be unstable and the charging speed would be slow. It is recommended to use an official charger or charging hub instead. Thanks.

Yes you can.   I bought this https://www.amazon.ca/gp/product ... e?ie=UTF8&psc=1 and while it charges 10 watts less than the recommended rate for the mini 3 it is still good in a pinch while out in the field.

why not? It works great. I bought a powerbank with PowerDelivery (PD) which does work great.    Enjoy your travelling and have always good and safety flights

I've used my phone power bank a couple of times to charge Mini3Pro batteries in the hub - but it does take ages

With a powerbank that supports PD with at least 45 watts it charges with the same speed as from the wall outlet.
Got myself a Zendure Supertank Pro that does a fantistic job as a fallback power supply.

USB-PD of 40w or above is fine.
I did a week long hike charging from power banks that way. Worked fine.
