10 Best Cordless Portable Air Conditioner 2025 in the United States

The BLACK+DECKER Portable Air Conditioner offers a solid cooling capacity of 12,000 BTU ASHRAE (8,000 BTU DOE), making it suitable for rooms up to 550 square feet. This unit is versatile with its three-in-one functionality as an air conditioner, dehumidifier, and fan. The Follow Me remote control feature is particularly useful as it allows for precise temperature control by acting as a thermostat wherever the remote is placed.

The installation kit and easy mobility with casters and side handles add to its convenience. However, it's important to note that this is not a cordless unit, so it requires a continuous power source and does not offer battery-operated portability. The noise level is moderate at 52 dB, which might be noticeable but not overly disruptive for most users. The energy efficiency, with a SEER rating of 5.8, could be better compared to other models in the market.

Additionally, the unit is relatively heavy at 56.8 pounds, which could be a consideration for some users despite its portability features. The auto water evaporation and environmentally friendly R410a refrigerant are nice touches for added convenience and eco-friendliness. This product is well-suited for users looking for a portable AC with good cooling capacity and multiple functionalities for medium-sized rooms.

The Dreo Portable Air Conditioner offers strong cooling power for small to medium rooms, with 8,000 BTU (ASHRAE standard) effectively cooling up to about 150 square feet. It runs quietly at 45 decibels, which is gentle enough for bedrooms or workspaces. Although it’s called portable, it requires a standard AC power source and doesn’t have a built-in battery, so it’s not cordless and best used near an outlet. The unit is fairly easy to move thanks to caster wheels and comes with a window kit for exhaust setup.

This model stands out with its drainage-free system that automatically evaporates excess moisture, eliminating manual water draining in most conditions. Its smart features include app control, voice commands compatible with Alexa, Google Home, and Siri, and customizable settings like a sleep mode to enhance comfort. It also offers three cooling modes (cool, fan, dry), adding versatility for different climates or needs. Using R-32 refrigerant indicates a more eco-friendly approach compared to older models.

The air conditioner weighs 55 pounds and measures about 25 inches tall, making it portable but not lightweight for frequent moves. If you want a quiet, smart, and easy-to-use portable AC for personal or bedroom use and don’t require battery operation, this is a solid choice. For truly cordless or battery-powered cooling, you may need to look elsewhere.

The Dreo Portable Air Conditioner is a solid choice for cooling small to medium bedrooms or rooms up to about 150 square feet. Its 8000 BTU cooling power is suitable for providing quick, effective chills, and the temperature can be precisely adjusted between 61°F and 86°F. One of its standout features is the patented noise isolation system, keeping sound levels low at around 45 decibels—quiet enough not to disturb sleep or work. Another practical design element is the drainage-free system, which automatically evaporates water, so you don’t have to worry about emptying a tank frequently, even in humid conditions. Although it’s called portable, it weighs 55 pounds, so while the caster wheels help move it around indoors, it’s not something you'd carry easily for outdoor use.

The unit supports smart controls via an app and voice assistants like Alexa and Google Home, making it convenient to adjust settings remotely. It also has fan and dry modes in addition to cooling, adding versatility. It does not run on battery power, so you’ll need an electrical outlet nearby, which may limit true portability. Energy efficiency is decent with a SEER rating of 6.1, though not the highest in its class. Installation is straightforward with included window kits and exhaust hose.

If you want a quiet, smart, and easy-to-use portable AC for indoor use without dealing with water drainage hassles, this model fits well. However, it’s less suited if you need cordless or very lightweight options.
