I’ve worked as a licensed heating, ventilation, and air conditioning (HVAC) engineer for over a decade. I know that battery-powered ac units are one of the most misunderstood areas of HVAC.

Although these units exist, they aren’t what most consumer expects, and some units that are described as battery-powered air conditioners by manufacturers aren’t actually battery-powered ACs.

I’ve used my years of experience to find the top battery-powered ac units on the market to help you make the best choice. With my buying guide, you’ll be sure to know what to look out for when comparing the different options of battery-powered air conditioners.

Battery-Operated Air Conditioner Buying Guide

There are many features to consider when choosing the right battery-powered AC for your personal cooling needs. Let’s take a closer at what to consider when deciding on the best air conditioner.

Air Conditioners vs. Air Coolers

It is easy to become confused between air conditioners and air coolers. They look very similar, but they use different cooling systems.

Air Conditioners

An air conditioner uses a chemical coolant to cool warm air. The cooling fluid flows through a series of coils. The refrigerant that passes through these coils removes heat from the air. The cool air is then blown into the room while a hose vents the hot air.

Air conditioners are best for cooling areas quickly and for longer periods.

Air Coolers

An air cooler looks like an air conditioner but uses a different cooling process. An air cooler uses cold water and evaporative cooling rather than a chemical to cool the air.

A fan draws air from outside and passes it through wet pads that cool the air through evaporation. Water is continually pumped onto the pads to keep them moist.

Air coolers are ideal for a small space and add moisture to the air, so they work as a humidifier too.

Charging and Operating Times

Battery-powered air conditioners have different charging options. Some portable units can be plugged directly into an electricity unit, while others charge via a USB or even a car charger.

Generally, a battery AC unit can run for 3-5 hours, depending on the speed that you are running the system at. Most battery-operated ACs take 4-5 hours to charge, but you can generally use the air conditioner unit while it is charging.

Power Source

The type of power source is a big consideration when choosing the best battery-powered AC unit for your needs. Most models have a rechargeable fixed battery or a removable battery pack.

An AC unit with an internal rechargeable battery is generally the cheaper option, and you can simply plug the unit into a power outlet to charge the battery.

Keep in mind, though, that if the battery fails, you will have to replace the entire battery air conditioner.

You won’t have this problem with portable air conditioners that use replaceable batteries, but they will be more expensive to run because of the cost of replacing the batteries.

Coverage Area

While battery-operated air conditioners aren’t as effective as traditional air conditioners, they’re still great at cooling small spaces of up to 100 square feet. This makes battery air conditioners a great option for personal use in a small space, camping trips, or cooling your RV.

(Video) EcoFlow Wave PORTABLE Battery Powered Air Conditioner 4000 BTU

The cooling power of air conditioners is measured in British Thermal Units (BTU). The BTU rating will vary by brand, size, and type.

The BTU rating doesn’t really apply to battery-powered ACs because they aren’t designed to cool large spaces. You would be better of using the temperature range as a guide to how much cooling you can expect.

Noise

If you are looking for a battery-powered AC to keep you cool as you sleep, you want to make sure that it isn’t too loud.

Most battery-operated units run at under 60dB, which isn’t that loud, but it’s still something to keep in mind.

Warranty

Ideally, you want to make sure that the product you buy has a warranty. When shopping online, you don’t always have a guarantee of the quality of the product or the state that it will be delivered to you in.

This is especially important if you are investing in a more expensive product.

Battery Powered AC Unit Reviews

Choosing the best battery-operated air conditioner can be challenging. To make shopping easier, I have reviewed the top five battery-powered air conditioners available now.

Best Battery-Powered AC

Zero Breeze Mark 2 Battery Powered Portable Air Conditioner

Editor’s choice

Best Battery Powered AC Unit 2022 - HVAC Judge (2)

Check price on Amazon

Features

Easy to use

Adjustable fan speed

Lowers ambient air temperature by 30 degrees

The Zero Breeze Mark 2 is a revolution in portable ac units and is suitable for indoor and outdoor use. The original Zero Breeze model had a couple of additional features like a USB charging station and a Bluetooth music player, but the company scrapped those for this updated model. One of the upgrades from the original Zero Breeze is the extension hose for the cool air discharge and the dual air intake hose.

This cooling unit has a 24-volt lithium-ion battery that will ensure cooler air for up to five hours. This unit comes with an ac adapter that can be plugged into a power outlet to recharge the battery. It takes 5-8 hours to charge, but you can swap out batteries for extended use. It does a great job cooling down small rooms, tents, or even RVs.

The Zero Breeze weighs only 16.5lb, so it’s much lighter than most portable AC units and can easily be carried around in one hand. This unit has a small but powerful compressor and can drop the ambient temperature by 30 in just 10 minutes.

This battery-powered unit has four fan speeds, and the powerful 2300 BTU microprocessor can cool up to 200 square feet. The BTU rating puts this unit in a class of its own because none of the other battery-operated ACs on the market come even close to this cooling power.

The Zero Breeze Mark 2 also comes with a nifty LED light and a USB charging port on the base to charge small devices like a bluetooth speaker while on the go.

This unit is on the louder side and runs at 52dB, but it is still quieter than a traditional AC.

This battery air conditioner comes with a hefty price tag, but its performance and warranty make it a great investment.

Battery-powered AC unit FAQs

Do battery-powered air conditioners really work?

Yes, battery-powered air conditioners do really work. It’s important to remember that they don’t have the cooling power of a traditional AC and are not designed to cool large spaces.

A battery-operated AC works well, though, for personal, close-up cooling or small spaces such as a tent or RV.

Can you run portable AC on battery?

Portable air conditioners are designed to run on 120-volt household electrical voltage. Small batteries like AA rechargeable batteries don’t stand a chance, but a lead-acid battery can provide sufficient power to run an air conditioner, but the air conditioner can’t use the lower voltage or type of current that a battery provides.

A power inverter can be used to change the battery’s direct current into an alternating current. This alternating current is then passed through a transformer to increase the voltage to match the household electrical voltage.

How can I maximize the lifespan of the battery of my portable air conditioner?

The first thing you want to do is keep the battery healthy by fully discharging it every couple of weeks. This will ensure that it stays in top working order. The only batteries you don’t need to do this with are Li-Ion batteries which do not possess a memory and are therefore not susceptible to this effect.

You also want to keep the batteries clean by wiping off their contacts with a cotton swab and alcohol. Doing this will help to maintain a solid connection between the battery and the aircon.

Exercising the battery is another important thing to keep in mind. You don’t want to leave the battery inactive for long periods of time. I recommend using the battery at least once every couple of weeks to keep it performing well. And if the battery has not been used for a long time, perform a new battery break-in procedure.

How you store the batteries will also have an effect on lifespan. If you don’t plan to use the battery for a month or more, store it in a clean, dry, cool place away from heat and metal objects.

NiCad, NiMH, and Li-Ion batteries will self-discharge during storage, so remember to recharge the batteries before use. Sealed Lead Acid (SLA) batteries must be kept at full charge during storage. This can be achieved using a trickle charger. If you do not have one of these chargers, do not attempt to store an SLA battery for more than three months.

My final thoughts

Battery-powered air conditioners are not as powerful as traditional air conditioners, but they have a definite purpose.

If you’re traveling or a fan of the outdoors but like to stay comfortable, battery-powered AC units are definitely the solution for your portable cooling needs. Portable battery-powered units are also a lifesaver if you live in an area with regular power outages in summer.

Make sure you do your research and consider all the pros and cons of the different battery-powered ACs before making your choice.
