Then switch scales and check for 12 v on the output side. (actual voltage could be more like 13.6 v or more)
An inverter is used to convert 12 v DC to 120 v AC when generator or shore power is not going. They don't have 12 v charging capability since the consume 12 v DC.
A "converter" will only "charge batteries" if it has "charging circuitry", (which makes it a "converter/charger").
Different RVs have different equipment, (depending on make, model, year, and what has been changed/added).
They will/can have:
1.) A "battery charger", which ONLY charges the batteries.
2.) A "converter", which ONLY converts 120VAC to 12VDC.
3.) A "converter/charger", which converts and charges.
4.) An "inverter", which ONLY converts 12VDC to 120VAC.
5.) An "inverter/converter", which inverts and converts.
6.) An "inverter/charger", which inverts and charges.
7.) An "inverter/converter/charger" which does all three.
8.) Any combination of the 7 listed above.
My coach, for example, (as built by SMC in 1996), has a "Heart Freedom 20 Inverter/Charger", which is a combination inverter, converter, automatic 3 stage battery charger, AND an automatic "transfer switch".
BTW, ONLY my house batteries are charged by my "inverter/charger", (which is often the case on motor homes).
