I had a portable inverter/battery unit. I hated it because it was extremely heavy and difficult to move around. I never used it in my RVs though.
Enter Lithium batteries..Jackeries largest power station only weighs 22-23 pounds but I know what your talking about,I have a group 24 agm in a smart battery box with volt meter and two marine sockets and it is heavy compared...I'm afraid I'll break the plastic handle on the box, so I use the end handles..
After our last power outage, I wanted something that did not require gasoline for the house..
