              • Easy to install – pre-assembled wheels, include quick setup guide and window mount kit
              • High efficiency – the coverage of 450 square feet while the BTU rating is just 10,000
              Cons
              • Not include batteries in the package
              • A bit heavy

              While all portable air conditioners require some assembly, SereneLife tried to make those tasks extra simple and effortless.

              All the wheels are pre-assembled before delivery. On the other hand, they provide a quick setup guide and window mount kit in the package. A remote controller is also included, therefore, you don’t have to leave your couch to adjust the machine.

              Aside from its minimalist, easy-to-install construction, our testers were amazed by how efficient this portable air conditioner is. With 10,000 BTU, it can cover a nearly 2x larger area (most similar counterparts only cover around 250-300 square feet of space).

              • Energy-saving – a 24-hour timer
              • Ideal for small rooms – compact size & the coverage of 250 square feet
              Cons
              • The window installation kit doesn’t fit great

              In terms of maintenance, we find this unit is the easiest. Its air filters are removable and washable for reuse; all you need to do is slide them out, rinse through, and pre-install – just twice a month.

              Another feature that we really appreciate is the drain collector design for dehumidifying mode.

              It’s in the back of the unit so when the tray gets full, just detach it for removal. Meanwhile, some portable air conditioners require you to lift the entire unit for drainage, which is obviously not suitable for women, girls, and the elderly.

              How To Choose The Most Powerful Portable Air Conditioner?

              Room Size

              To choose the most powerful portable air conditioner, considering the room size that you intend to use it is a must. The larger the room area, the more power it will need to cool down.

              Portable air conditioners are categorized by the heat quantity they can dissipate in British Thermal Units (BTU), the power input in kilowatts (kW), or both.

              Our experts find that the general amount of power needed for most portable ACs is somewhere between 2900kW and 5200kW. Meanwhile, according to Canstar Blue:

              • 215 square feet can be cooled by a 2800kW system
              • 325 square feet by a 4200kW system
              • 430 square feet by a 5600kW system

              Maneuverability

              Unlike central air conditioners, the portable models can’t be used for the entire house or apartment but just a certain space. But it can be moved from room to room.

              Therefore, considering a unit with rolling wheels is quite practical.

              It would be better if the portable air conditioner is lightweight and compact in size as well.

              Noise Level

              If your new portable air conditioner is used for a bedroom, kid room, or home office room, it should be as quiet as possible. Noise level is another important feature to keep in mind, from that point!

              With portable air conditions, noise is commonly released from the fan during operation.

              The higher the speed mode, the louder. Therefore, it is good to choose a model with multiple fan speeds for different uses. The ideal noise range of a portable AC for a bedroom should be under 55 decibels.

              Besides, a Sleep Mode would come in handy for quieter operation.

              Which Brands Make The Most Powerful Portable Air Conditioner?

              Black+Decker

              Black+Decker was established by Alonzo G. Decker and S. Duncan Black, in 1910 in the USA. A company specializing in manufacturing and distributing home appliances, home improvement products, power tools, and more.

              Honeywell

              This American company was founded in 1906 and is currently based in Charlotte, North Carolina. In 2019, they were ranked 92nd out of 100 companies voted by Fortune.

              FAQs

              Are Portable Ac Units Any Good?

              A portable AC is really good for cooling a certain space, depending on its capacity. In comparison, it works far better than a fan and more space-saving than a window AC.

              What Is The Highest BTU For A Portable Air Conditioner?

              It is usually 14,000 BTU as the highest rating for a portable air conditioner.

              Can you run a portable AC all day?

              No, you can’t. You should not run a portable air conditioner 24/7 because it might put a strain on the unit to shorten its lifespan quickly while wasting a large amount of electricity.

              Do portable air conditioners use a lot of power?

              It depends. If you choose the right portable AC for your room space, it will consume less energy than using a central air conditioner.

              How much will a portable AC raise my electric bill?

              According to the estimation of the U.S. Energy Information Administration in 2014, using a portable AC for 8 hours/day in California (supposed that the energy cost is around 16.18 cents/kW) costs around $2.84 to $5.31.

              Conclusion

              Have you found out the most powerful air conditioner for your needs?

              Which is your most favorite option out of the ones we’ve listed? Kindly let us know, we love to hear from you as much as possible. At last, thanks a lot for reading!
