Rather than rewire my entire RV I am thinking of getting 2 of either the Delta Pro or AC300max with their connections to supply 240 volt 30 amp AC. If I plug in an adapter from the 30 amp NEMA L14-30 to a 50 amp RV receptacle will it successfully power both halves of the breaker panel (with 30 vs 50 amps 120 volt)? The Bluetti AC300 seems to have a problem balancing the loads (which may be fixed). Will, you seem to be the only one who has reviewed the Ecoflow double voltage hub and so I bow to your expertise!!
