Low Power

I am new to 5th wheel game. Anyway I am keeping a 36' RV with dual RV's in South Texas. Last time I was there it was about 100 degree heat and my a/c's were not cooling. It was 90 in the trailer. The other campers said the power was bad (low power) and that compressors were not kicking on just the fans.
The wiring to the plug look a little small but i can't tell

I saw a Hughes or Franks power booster for sale . Would that help?
any ideas?

also the refrigerator was not working either. The freezer gradually worked. I thought about replacing it with an electric a/c refrigerator. any thoughts

  • Also, remember that RV A/Cs typically only cool only 20 or so degrees lower that outside. Like 100+ outside, 80+ is what your gonna get inside.
  • You bet it will affect anything you are trying to run. Low power is decidedly dangerous to all of your systems. No, a power booster won't help. Make sure, first, that you are using 50 amps. If not, you gotta turn things off.
  • You should also know that unless you are plugged into 50 amp service, using anything with your AC would cause it to fry. 30 amps are not sufficient for two AC units, nor is it able to run anything else with youAC.
  • yeah I need to check the voltage

    Would low power affect the RV refrigerator performance?

    would the power booster help if it were low?
  • In a word: NO. If you got a power booster and used it, it may possibly boost a little. BUT, to get that boost, it will rob from other campers. If you have low power and try to use your high-power items such as AC, you may well fry them. Don't do it. I would find someplace that doesn't have low power. That is the reason your refer and freezer only work a little. Trying to use your AC, Microwave, refer or other appliances at the same time in your conditions WILL fry something, usually AC. Don't do it, go somewhere else. Have a meter so you can check the voltage wherever you go before hooking up and drawing a ma
  • Did you ever think about checking the power?? Get one of those plug-in voltage meters and use it. If the A/Cs wouldn't work on the power you have/or had, why would you think that an AC refrigerator would work better either?? Or use less AC power??
