Yes I hated that with the hub they offer. Even if your out remotely , you would have to wait for a decent charge. So I opted to get the energen portable Multi charger. That helped with charging 2 batteries simultaneously. I’m looking now for a multi charger for the Autel. Thanks for the clarification on this. I would watch, both options, and yes , when in the blue setup , it takes awhile longer for all to charge. I do take the hub with me when I’m out doing a few jobs during the soirée of the day. Need an alternative.
