When the summer heat hits, the last thing you want is for the power to go out. What happens if your portable air conditioner stops working during a power outage? A portable gas generator can keep your portable air conditioner operating if the power goes out, but there are a few things to consider first.

1. Can a Generator Run a Portable Air Conditioner?

Yes, but you must first verify that the generator can accommodate the air conditioner’s wattage. Be mindful of the wattage your portable air conditioner unit uses. If the AC unit draws too many watts, it could overload the generator. Finally, keep in mind that operating an air conditioner puts a strain on the generator, so you’ll need a higher wattage generator than you would for other appliances.

2. How To Make Sure Your Portable AC Can Run On a Generator?

The first step is to make sure you choose a generator that’s powerful enough to run your portable air conditioner. Check the specs of your portable AC unit to find out how much power or wattage it uses. Then choose the proper wattage generator that can provide at least that much power. A 2000-watt generator is usually enough as most 6000 to 10000 BTU portable air conditioners use less wattage.

This will vary by each generator and portable AC. Once you’ve chosen the right generator, you’ll need to connect your portable air conditioner to it. Most generators will have a specific 110v outlet for connecting to any appliance such as a portable AC – just follow the instructions in your AC and generator manual.

3. What You Need To Know Before Running a Portable AC On a Generator?

If you want to use a portable air conditioner on a generator, there are certain things to consider. Here’s what you need to think about before connecting your portable AC unit to a generator.

1. Check the wattage of your air conditioner and generator.
Before hooking up your portable air conditioner to a generator, make sure the generator has enough power to run the unit. Most portable air conditioners require at least 1,000 watts of power to operate depending on the BTU (British thermal units).

2. Make certain that the generator is well ventilated.
When utilizing a portable air conditioner on a generator, it’s critical to make sure the machine is sufficiently ventilated. If the generator isn’t sufficiently ventilated, it might overheat and ignite a fire. Do not use the generator in a closed space as the exhaust is harmful in confined spaces. Use the generator outside and not near any other objects.

3. You will need a heavy-duty extension cord.
Most portable air conditioners have a large power plug that won’t fit properly on most generators. The power cord on the portable AC has a large reset button on the back for safety reasons. So, considering this, when running a portable air conditioner on a generator, it’s important to use the proper extension cord. Use a heavy-duty 20 to 30 amp or better extension cord. A regular extension cord won’t be able to handle the power required by the air conditioner and could overheat and stop working.

4. Before shutting down the AC, allow it to cool down.
When you’re finished using your portable air conditioner with a generator, it’s important to let the unit cool down before turning off the generator. Turn the AC completely OFF before you power down the generator. Then give it a few minutes to power down, never turn the generator OFF while the portable AC is running in cooling mode. This will help to prevent any damage to the AC unit from sudden power loss.

4. How To Choose The Right Portable Air Conditioner?

When shopping for a portable air conditioner, you’ll want to consider the size of the unit, the type of cooling it uses, and the features that are important to you. Find the correct BTU portable AC unit. You want to match the portable AC up with the wattage of the generator.

An example would be = If you have a 2000-watt generator, it would power a 5000 to 8000 BTU portable AC, as long as the max wattage of the AC does not go past the max wattage of the generator.

Also keep in mind that portable air conditioners come in a variety of sizes, and you’ll want to choose one that’s large enough to cool the space you plan on using it in. And finally, you’ll want to consider the features that are important to you, such as a remote control or an automatic shut-off timer.

5. What Size Generator Wattage For Portable AC BTUs?

The size of the generator you’ll need to run a portable air conditioner will vary depending on the specific model of the air conditioner. However, most portable air conditioners require a minimum of 1,000 watts to operate. Therefore, we recommend choosing a generator that produces at least 1,500 watts.
