We have a 12v outlet (looks like a cig lighter in an auto) that works on battery and constant power. Should reg outlets work on battery power???
Thanks in advance
Your regular 110vac outlets only work when the trailer is hooked up to a 110vac power source; usually the power post in a campground or a wall outlet of some kind at home.
The 110vac power runs your convertor
which puts out 12vdc which in turn charges your battery and helps run the other 12vdc appliances and fixtures. Your fridge and water heater, depending on model, may also optionally run on shore power. If your rig has an air conditioner, it is generally 110vac only.
Unless the trailer has been modified with the addition of an inverter
, that's the extent of the interaction between the 12vdc system and the 110vac system. If there is an inverter
, it takes 12vdc and produces some 110vac but there's a lot of loss, and unless you have a monster battery system, you're not going to run your AC or water heater on the 110 produced by the inverter.
