Portable power for Smart controller

[freddy5]

If away from a power source, what portable power charger works to charge a Smart Controller? Should the smart controller be powered off when using a power bank?

Hi freddy5 Welcome to Mavic Pilots
I have a power-bank that takes 3 – 18650 batteries & can connect this while flying, simply pop it in a pocket and have a cable connected.
I would think any power-bank should work OK
