Can my RV with 30 Amp hookup be connected to my Ecoflow Delta Pro parked at a EV station charging my ecoflow using the J1772 connection while i run my Air conditioner in my RV for my 2 siberian huskies for 2 plus hours while i step out for a bite to eat. Has anyone done this and is it safe for my RV system that has a lithium battery system running the RV to be running and charging my ecoflow at the same time.
