How Many Watts Does An RV AC Use ?

Air conditioners in an RV are very popular and almost essential now. It would be best to have a cooling machine to help you sustain the weather. However, air conditioners are one of the most power-hungry appliances. Therefore, you must know how many watts an RV AC use so that you can choose a suitable power source.

On average, a 10,000 BTU unit can draw between 700 and 1,500 watts for a 15,000 BTU unit.

Key Takeaways About RV AC Wattage

  • How many watts does an RV AC use? Typically RV air conditioners use between 700 and 1500 watts of energy.
  • Using the air conditioner for 12 hours a day makes 8400-watt hours to 18000-watt hours a day.
  • Since it is a huge energy consumption, it is very expensive. Solar power generators are the best option for a cost-effective and portable energy source for RV air conditioners. Jackery solar generators have high-capacity portable generators that are robust, reliable, and portable. Hence they fulfill all requirements for the best RV AC power source. They offer MPPT technology for a stable fluctuation-free power supply and have a quick recharge time using both solar panels and AC outlets.

How Many Watts Does An RV AC Use?

How many watts an RV AC use depends on many factors, including the BTU, size, brand, and stage of the air conditioner. For example,

RV AC Watts Consumption of Atwood Air Command, Coleman-Mach 3 Power Saver, and More

As we discussed, the size and brand of the RV determine how many watts an RV AC uses. High-capacity air conditioners use 1500 to up to 3500 watts, while smaller ones can do 700 to 1250 watts.

Let us summarize the wattage consumption of the most popular RV air conditioners.

RV Air Conditioner

Furrion Chill

1620 watts



Dometic Penguin II High Efficiency (Low Profile)

‎1300 watts



RV AC Watts Consumption Based on Stage

The two most important working stages of RV air conditioners are a startup and running wattage. Startup power is the maximum power surge an AC requires to start working. In comparison, the running wattage is the continuous working wattage of an AC.

RV Air Conditioner Size

Watts Required for startup

Average wattage once running

7000 BTU



10,000 BTU



13,500 BTU



15,000 BTU



What Size Generator Do I Need For RV AC When Off Grid

The generator size you need to run an RV AC when off-grid depends on your required air conditioner size and how long you want to run it. Since an air conditioner requires substantial energy to run, you need a powerful solar generator to support it. Jackery solar generators are available in high capacity, including but not limited to 1000-watt hours, 1500-watt hours, and 2000-watt hours.

The statistics mentioned above are based on full charging. However, when you connect the solar panels and the sunlight is available, the working hours of the air conditioner are increased. The Jackery solar generators support pass-through charging, so you charge the generator and use the power simultaneously.

Another important point to understand about the statistics is that there is always some loss of power during the transmission and operation of a generator. Therefore, we have calculated the working hours based on 85% percent efficiency to make the estimates more realistic.

How to calculate the hours: Working time = Capacity Wh * 0.85 / operating wattage of your device

For example, assuming the power consumption of your RV AC is 1250 Watts.

The Jackery Solar Generator 2000Pro Working time will be 2160Wh * 0.85 / 1250w = 1.5 hrs.
