Why Choose a Battery-Powered AC Unit

A “normal” powered air conditioner - one that draws on your house’s current - would be your obvious choice to cool a space in most circumstances where you have perpetuity of electricity. But in those rare cases when there is no electricity you would need to choose a battery-powered AC unit.

This works best in a variety of circumstances. Maybe you are camping in the woods in the summer roughing it in a tent but you don’t want to rough it too much. If you’re working or living in an area with frequent power outages, you might also want such a unit as a backup. If you’re traveling and need to cool a trailer or camper, it’s also a good option. It can also be carried for recreational activities at the beach, on a boat, or at sporting events.

you can have air conditioning in a tent!

Battery-powered AC units are a must when you want to cool a tent or other small space. If you need a unit to work its best in humid and hot circumstances and can’t rely on a power line, these units will serve you well.

You can also consider this type of air conditioner to cool a caravan or a truck that does not have a centralized cooling system. Since these vehicles are often used for camping and long travel, these easily portable AC units can be used en route to and at the destination without any electrical connection.

Some portable battery powered AC units can even be used to cool ice and drinks - and that’s definitely a key point!

How Much Cooling Can You Really Expect

Portable and battery powered AC units are designed to cool spaces from 50 to 250 sq. ft. This signifies that such units come with a rating between 500 and 1500 BTU.

These units typically run on 12 volt batteries, on as little as 40W, and run for about 10 hours.

These air conditioners weigh anywhere between 10 lbs. and 70 lbs. This is not directly related to the efficiency, but matters a great deal during the movement.

If you are traveling or camping for more than a few hours, you can turn them off while not in use or switch to fan mode. Another useful feature is that some of them also come with a wall adapter so that they can be charged while you are back home.

Some units use ice and water. Of course, it’s important to check occasionally for leakage in such cases.

Some units can keep the temperature as low as, 35 degrees Fahrenheit for about 10 hours, while others may work that efficiently just for an hour. Though the manufacturers do not mention explicitly, the performance of these units also depends on the temperature of the external environment.

When comparing prices, you should note whether a particular unit is built to perform both indoors and outdoors. Then choose according to your needs.

Review of the Best Battery-Powered AC Units

When you are purchasing a battery-powered AC unit, you need to measure the product based on a few parameters. Some of the most important parameters are, BTU rating, power consumption of the AC unit, how long the unit will run on battery while cooling, weight of the AC unit and the temperature in which it can perform effectively. One caveat, if you are expecting silence with these units, then you could be disappointed. But maybe they’ll drown out the crickets and the howls of the wolves while you’re camping.

With units that use water, you need to calculate the weight of the air conditioner with and without ice and water in it. A gallon of water is the same as 3.78 liters. A gallon of water weighs about 8.34 pounds.  Also, remember that the majority of these units use ice and water to cool so keep them at a distance from anything that should not get wet.

Pros and Cons of Battery-Powered Air Conditioners

Just like a normal-sized and normal functioning air conditioner, a battery-powered air conditioner has a couple of pros and cons attached to it. To make this easy for you, let us go through the pros and cons.


Let’s first start with the pros: 


Battery-powered air conditioners are generally available at an affordable price. Central air conditioners usually come with a high price tag, plus with the cost of labor and installation, it is a heavy investment. So keep things light and breezy by getting yourself a cost-efficient mini, battery-powered, air conditioner.

Easy Installation

Such air conditioners don’t need an entire team for assembling and installing. Although it is very easy to assemble battery-powered air conditioners, if you are stuck somewhere, you can always open up that manual.


Usually, battery-powered air conditioners come in a small size, so they can be moved easily from one place to another. This makes them perfect to be taken hiking and camping and other expeditions.

Now let us have a look at the cons:

Room Size

The cool breeze of battery-powered air conditioners only covers a limited area. So, if you are thinking about getting a battery-powered air conditioner for a large room, then this is not a wise idea.

But when you’re on the road or out in the wild, this makeshift solution can save you from a great deal of heat.
