I seem to be getting fast charging from this powerbank but it appears to only charge my DJI Flip batteries in the charging hub individually. On mains, the hub can charge two at a time.

Based on the the image below, is there any likely speed benefit in using multiple ports on the power bank at once and charging multiple batteries without the hub, one per cable?

Provide some further info on the power bank you’re using and we’ll be able to offer up an answer.

My EcoFlow River 2 Max has a 100w output USB C port, along with 3 x USB A ports and 2x 240 volt 3 pin plug sockets.

I believe the output wattage is insufficient, needs something in the order of 60w. I use an Anker power bank 140w.

Specs of the hub

_Charger Power \<65 W Charges in sequence from highest to lowest battery level._  
_Charger Power ≥65 W Charges two batteries simultaneously: First charges the battery with the second_  
_highest battery level until it matches the battery level with the highest charge, then_  
_fully charges both batteries together._

This I have also and does a pretty good job at charging drone batteries. A little cheaper.
