10 Best Smallest Portable Ac Units 2025 in the United States

The BLACK+DECKER Portable Air Conditioner, with 10,000 BTU ASHRAE (6,300 BTU DOE), is a versatile unit suitable for cooling rooms up to 450 square feet. Its size (15.3” x 14” x 24.8”) and portability, aided by casters and side handles, make it easy to move around.

The unit operates quietly at 52 dB, which is relatively low compared to other models, making it a good choice for bedrooms or workspaces where noise might be a concern. The air conditioner also doubles as a dehumidifier and fan, providing additional utility. Energy efficiency is average with a SEER of 6.7, which may result in higher energy consumption compared to more efficient models.

The Follow Me Remote feature allows precise temperature control by using the remote as a thermostat. An easy-to-install window kit is included for convenient setup. However, the capacity of 0.45 liters for dehumidification might be low for very humid environments. This unit is ideal for someone looking for a moderately powerful, quiet, and portable AC unit with added dehumidifier and fan functions.

The BLACK+DECKER Portable Air Conditioner offers 10,000 BTU cooling power, making it suitable for cooling rooms up to 450 square feet, such as apartments, bedrooms, or small offices. It combines air conditioning, dehumidifying, and fan functions in one unit, giving you flexibility for different weather conditions. It comes with a full-function remote control and an easy-to-install window kit, so you can operate it conveniently from across the room and set it up without hassle.

The unit is on the larger side for a portable AC at about 55 pounds, so while still moveable, it's not the lightest option if you plan to carry it around often. Noise level is moderate at around 53 decibels, which is noticeable but not overly loud for most indoor spaces. Its energy efficiency rating (EER) is 2.6, which is fairly standard but not particularly high, meaning it could use more electricity compared to more efficient models. The auto water evaporation feature helps reduce the need to manually empty the water tank, making it low-maintenance. However, it does consume about 890 watts, so it's worth considering your electricity costs if you run it for long periods.

The plastic build is typical for portable units but may feel less durable than heavier-duty models. This unit is a solid choice if you want a reliable, easy-to-use portable AC that covers medium-sized rooms with the added benefits of dehumidifier and fan modes, but if you prioritize ultra-quiet operation or top energy efficiency, there might be better options available.

The SereneLife Small Air Conditioner Portable 14,000 BTU unit is a versatile cooling solution suitable for rooms up to 700 sq ft. One of its key strengths is the high cooling power, making it effective for larger rooms. Additionally, it serves multiple purposes with its 3-in-1 functionality, acting as an air conditioner, dehumidifier, and fan, which adds to its versatility.

The built-in 24-hour timer, auto-swing mode, remote control, and LED display with push button control panel contribute to user convenience. Its sleek, free-standing design makes it aesthetically pleasing for use in various settings such as offices, bedrooms, and living rooms. The unit operates at a relatively low noise level of 57 dBa, which is fairly quiet for a portable AC unit.

The package includes a window mount exhaust kit and a removable air filter, making the setup process straightforward and maintenance easy. The unit's size (32 inches in depth, 18.5 inches in width, and 15.4 inches in height) might make it less portable for some users, especially if space is a concern. Despite these minor drawbacks, the SereneLife Small Air Conditioner offers a good balance of performance, convenience, and design for those looking for a multi-functional portable cooling solution.
