The Best Low Wattage Portable Air Conditioners

AT A GLANCE



Cooling down in the summer is always a struggle. Fans just don’t seem to do the trick and only circulate the same stale air, which eventually gets warm and ineffective.

With an air conditioner, you avoid those issues.

The problem is, however, that regular wall mounted air conditioners are not only expensive to buy and install, but they’re usually expensive to run. Not to mention that if you rent your home, you might not have the freedom to have one installed.

This is where portable air conditioners come in handy.

How many watts does a portable AC use?

The average portable air conditioner uses between 1200W – 1400W. It’s all dependent on model, BTU and how many square feet the unit covers.

If you live in a hot area of the world, it’s not unheard of to keep your ac running for hours on end, and this won’t be cheap in the long run.

So if you’re looking for a new portable ac unit, you should be looking for models that operate at 1000W and under.

Are portable air conditioners expensive to run?

They can be, depending on the model you choose. The more powerful the unit, the more energy it will drain, and thus the more it will cost to run.

How much will a portable AC raise my electric bill?

Let’s say your portable ac is 1200W, and you use it every day for 3 hours, at $0.20 per kWh (average rate across the US), that’s $0.76 per day – $22.80 per month.

This might not seem like a huge amount, but depending on how long you keep it on, and how powerful your unit is, you could incur much higher costs.

The selection of portable air conditioners we have for you today are some of the lowest wattage ac systems on the market, all 1050W and below. Getting one of these will go some way in keeping your utility costs down.

What is BTU in air conditioning?

BTU is an acronym for British Thermal Unit. In relation to air conditioning, BTU is a measurement that shows how much heat an ac system can remove from a room in your home.

Naturally, the higher the number, the more powerful the appliance, and the more space it will be able to cool.

It’s important to know the BTU of a particular air conditioner as you’ll be able to determine whether or not it will be suitable for the size of the space you plan to use it in.

Are portable air conditioners energy efficient?

Compared to window units, yes, portable air conditioners are energy efficient.

Portable air conditioners cool each room individually without having to circulate the cooled air throughout the house at high speeds using central cooling units mounted on ceilings.

This means that electricity won’t be wasted as you’ll only be cooling the room that you’re in.

You still need to be mindful of how you use your device, as buying a larger/more powerful unit for a small space would be overkill and would, essentially, cancel out the energy efficiency.

Does a portable air conditioner need a window? Does it pull air from outside?

The heat that the AC unit draws from the room has to be expelled somewhere, so there must be some kind of ventilation. Through a window is the easiest option, though because you’re free to put the exhaust hose anywhere, you could, in theory, position it in a hallway or another room. This is not advised, however.
