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.
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 room 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 volts batteries and on as little as 40W and run for about 10 hours.
These air conditioners weigh anywhere between 10 lbs to 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 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 at least 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.
