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?
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.
