asked in category: General Last Updated: 8th February, 2020# Will a 3000 watt generator run a 15000 BTU air conditioner?

**air conditioner**that

**will**need 13500BTU or

**15000BTU**to

**run**. An RV that has 13500

**BTU air conditioner will**need at least

**3000 watts**to start. Once it's up and

**running**, it

**will**need 50% less power like 1500

**watt running**. A

**15000 BTU**RV

**AC will**need 3500 to start and 1800

**running watts**.

Besides, how many watts does it take to run a 15000 BTU AC?

Wattage Chart

Motorhome 5th Wheel and Camp Trailer Roof Top Air Conditioners | Watts Required for start up | Average wattage once running |
---|---|---|

7000 btu RV air conditioner | 1700 | 600 |

10,000 btu RV air conditioner | 2000 | 700 |

13,500 btu RV air conditioner | 2750 | 1250 |

15,000 btu RV air conditioner | 3500 | 1500 |

One may also ask, will a 2000 watt generator run a 13500 BTU air conditioner? A **2000 watt generator** won't be able to power your hot water heater. A **2000 watt** handle the load of a 15000 **BTU** RV **air conditioner** with a higher starting **wattage** capacity **could** let you **run** a 10,000 **BTU** window **air conditioner** during a summer blackout. Once it is **running**, you have roughly 1800 **watts** left to work with.

Keeping this in consideration, what size generator do I need to run a 15000 BTU air conditioner?

Size of Air Conditioner | Approximate Starting Watts | Approximate Running Watts |
---|---|---|

13,500 btu | 2800-3000W | 1500-2000W |

15,000 btu | 3300-3500W | 1300-1800W |

What size generator do I need to run my air conditioner?

For a **generator** that you want it to **run** more than just a small **AC** unit, a 3200-watt **generator** could handle a larger **AC** unit and few more appliances. If you just want to cut throughout all the grey area and just play it safe. The 4000-watt **generator** covers even the largest RVs and lots of appliances.
