While the Ontel Portable Air Conditioner may be one of the smallest portable air conditioners and the best portable A/C for camping, it is also the best solution for cooling down a smaller area like an office or room where you can’t fit a traditional, leading air conditioner or even some of the bigger portable AC units. This neat little appliance won’t jack up your energy bill, and it can cool you down for hours on end.

Why We Like It – Ontel Portable Air Conditioner

The Ontel Portable Air Conditioner is a great solution for cooling down your personal space wherever it may be. It has an energy-efficient tank that can last a whole 8 hours from one fill. It does not use substances like freon and only needs some cold water to operate.

  • One tank of water can last about 8 hours
  • It is powered by USB
  • Only two fan modes


This personal space cooler covers a room up to 45 square feet and has 10,000 BTU power. It takes in the hot air around the room, and converts it to a cool refreshing breeze that leaves you feeling refreshed and relieves your room of humidity. It has an LED mood light with 7 different colors to match what you’re feeling that particular day. While this is our number one choice for personal air coolers if you would like to check out models outside of the brand Ontel, feel free to check out our runner-up, the Frigidaire FFRA0511R1 or the Perfect Aire 10000 BTU portable air conditioner.

Energy efficiency

The Ontel arctic ultra evaporative portable air cooler can last a long time on a full tank of water. It runs super quietly, so you won’t have to worry about it keeping you up at night. Another great part about it is that it takes about as much energy as your everyday small fan, so it will not be a costly upgrade. If you want an even cooler breeze, the unit in our Luma Comfort EC110S review can be further cooled by adding an ice pack to the water tank. If you would like to check out more similar air conditioners, you may be interested in the Honeywell Portable Air Conditioner 10000 BTU.


The evaporative air cooler filters out the humidity through its back portion, and blows out cold air through the front end. This device can cool your space for about 8 hours on a single tank. It does use a filter, so you must be willing to replace it every so often to not end up blowing moldy air out to you.


The Ontel Arctic ultra evaporative portable air conditioner requires a refill on its water tank after 8 hours of use to be at full capacity once again. If 8 hours isn’t long enough, you can get 12 hours out of the AC in this Breezewell 2-in-1 space heater & evaporative air cooler review. Ensure that you take the time to exchange its filter every once in a blue moon so that it does not accumulate mold and blows fresh cold air for you consistently. It is a fairly small device that can fit on top of any table or desk so it can be used practically anywhere. It is a lightweight device capped at 3 pounds, so be cautious of not dropping it from a significant height.

This is a great way to cool down your living space on a budget. This fits perfectly in your workstation at home, or you can take it on the road, and as long as you have access to electricity you will be able to hook up this air cooling device easily. You can precisely manage the temperature by degrees and condition the room as needed. It is a quiet unit, and it will cool down your space without using the refrigerant freon, so you don’t have to worry about being exposed to that all day. Right now you can take advantage of free shipping with your purchase as well.
