British Thermal Units (BTUs) help measure heat. One BTU is the amount of heat required to raise the temperature of one pound of water at sea level by one degree F.

The higher the BTU value, the greater is the AC’s cooling effect. Vehicles like RVs have their AC BTU values in the range of 13,500 to 15,000 BTU.

A Guide to Choose the Right Generator for 15000 BTU Air Conditioner

It means the vehicle’s AC can remove or add that many units of heat energy per hour.

A generator capable of running such an AC unit will always come in handy. Such generators are relatively portable and are usable in a range of temperatures.

The best generator for 15000 btu air conditioner is readily available in the market, with plenty of models to choose from according to your needs and budget.

Picking the Best Energy Pump

A generator is not a simple purchase and has a host of specifications that will influence that purchase.

One must be aware of those specifications and their meaning before going shopping for one.

The best generator for a 15000 BTU air conditioner is best picked after following a guide to its many specifications, like this one.

You can then make an informed decision and enjoy its many benefits.

The Starting Power Delivery

Every AC unit comes with its power draw specifications listed. Essentially, it will have a high starting power draw and a lower running power draw.

For 15000 BTU range AC’s, the initial power draw can be as high as 3500W, with the running power draw in the 1800W ballpark.

Your generator needs to have the power generating capacity to satisfy those power draws, particularly the initial high one.

It’s best to pick a generator that not only has a peak power output of that kind but a higher running output too so that it can support the other appliances besides the AC.


Weight becomes an influential factor for generators used to power RV ACs. RVs are designed to carry only a certain amount of load, and if the generator’s weight eats into that capacity, it means something else has to be ignored.

Note the weight of the generator and the RV’s maximum load capacity before purchasing it.

See if the additional weight doesn’t hamper the chance to carry other stuff. Don’t forget to note the wet and dry weights, as the wet one will ultimately decide the portability.


Stationary AC units can make do with large size generators, but those for vehicle use must be small enough to get carried around easily.

Its dimensions shouldn’t obstruct the placement of other objects to be carried.

Fuel Capacity and Efficiency

The higher the fuel capacity and efficiency, the longer the generator can run. Efficient generators also reduce the cost of operation.

Note that you will need to carry more fuel for a large capacity generator.

ACs, especially those on vehicles like RVs, can be lifesavers in times of high temperatures.

The best generator for 15000 BTU Air Conditioners will ensure that those ACs get the power they need to keep saving lives.
