+ | An //inverter charger// performs several functions: | ||
+ | - invert 12v battery power to 120vac | ||
+ | - pass-through shore power when available | ||
+ | - some can bond shore and battery power to support heavy 120vac loads | ||

Because higher voltage power has less losses over long wires, it may be most efficient to share power between RVs as 120v. The donor vehicle would invert to 120v, plug in an extension cord to their inverter and run it to the recipient. | Because higher voltage power has less losses over long wires, it may be most efficient to share power between RVs as 120v.
