The site says "Built-in load balancing allows you to charge multiple EVs at once by distributing power across connected chargers." If all the cars charge at the same time, I think it just balances the load automatically and doesn't charge each EV as quickly.I have 2 x 50Amp breakers with NEMA 14-50 outlets. I have a Tesla Wall Connector on one and a Wallbox PuLear Plus on the 2nd. When I eventually get rid of the Tesla, I will swap out the wall connector for a second wallbox unit. There’s no issue having multiple Wallboxes on one account.
