Offering 12,000 BTUs of power that cools rooms as large as 550 square feet, and the ability to function as a supplemental heater in winter, this air conditioner from Midea is incredibly strong and versatile. Plus, it can function as a dehumidifier or fan. It comes with three speed settings, an easy-to-see LED display, a 24-hour timer and a dedicated energy-saver mode.

We’re seeing a relatively small discount on our favorite portable air conditioner, but it’s still the lowest price we’ve ever noted for such a popular model. This machine is smart, efficient, versatile (it can also dehumidify and heat) and surprisingly quiet, which makes it a great option for areas like bedrooms or a home office. It takes up a bit more floor space than some of our other picks and requires a smartphone app to get the most use out of its controls.

If you’re looking for a simple, streamlined cooling solution, we recommend the SereneLife SPLAC10. This lightweight model is easy to set up and works quickly to cool your space. It doesn’t have any extra smart features and it’s most effective in smaller rooms (around 270 square feet). 

Why It’s A Good Deal: The model briefly dropped below $300 in April, but this discount is otherwise the best price we’ve seen since February.

Shinco makes one of our favorite dehumidifiers too, so we know it’s a reliable brand in the appliance category.
