How much power does an RV need?Updated 17 days ago

RVs generally come with either a 30-amp or 50-amp power inlet (power cord). A 30-amp connection can provide a maximum of 3,600 watts. A 50-amp connection can provide a maximum of 12,000 watts.

But most of the time, an RV doesn't need that much power. Real-world power needs are usually much lower.

If you have a 50-amp trailer, you can connect to the Sorein Power Station using a 50-amp to 30-amp adapter. These are sometimes called "dog bones" or "dogbones". AIR GEAR sells the appropriate 50 amp to 30 amp adapter here: AIR GEAR Nickel-plated Power Adapter Set

Managing power usage to avoid overloads

When camping with a power station or a generator, it's important to manage your power usage in order to avoid overloading and/or short battery life. We suggest these tips:

  • Run appliances on propane whenever possible. This includes the water heater and refrigerator in particular. For heat, use the gas furnace instead of the heat pump.
  • Don't run the air conditioner and microwave at the same time.
  • Consider installing a soft-start device on your air conditioner.
  • Turn off the on-board inverter when you are connected to a generator or power station. The power station's inverter will energize all of the outlets, so the on-board inverter will not be needed. Also, the on-board inverter consumes power anytime that it is on.
  • Avoid using high-wattage appliances like toaster, hair dryer, electric skillet, air conditioner, microwave, etc. Anything with a large motor or a heating element will be a high-wattage device.
  • If the on-board batteries in the RV are discharged below 50%, allow them to recharge to at least 80% from the power station or generator, before attempting to run any other AC-powered appliances.

If you follow these tips, your RV's power consumption will usually be in the range of 100-1,000 watts. This will ensure that the generator or power station never overloads, and yield much longer battery life from a power station.
