The built-in dehumidifier is particularly useful for reducing humidity levels, and the fan offers three speed settings for varied airflow.

The unit is equipped with smart features such as a 24-hour timer, auto-swing mode, and self-evaporation technology, enhancing convenience. Control is straightforward with the remote and LED display, making adjustments easy even from a distance. The noise level is relatively low at 57 dBa, ensuring minimal disruption in an office or living room setting. The portable design allows for easy relocation and setup, aided by the included window mount exhaust kit and removable air filter that simplifies maintenance.

Despite some minor drawbacks regarding its size and weight, the SereneLife portable air conditioner is a versatile and convenient option for those needing effective cooling with added smart features.

The BLACK+DECKER Portable Air Conditioner with 12,000 BTU (ASHRAE) or 8,000 BTU (DOE) is a versatile unit suitable for cooling rooms up to 550 sq. ft. This model is a three-in-one device, working as an air conditioner, dehumidifier, and fan, making it a practical choice for various needs. Its cooling capacity is robust for medium-sized rooms, and it includes the 'Follow Me' remote control, which helps ensure precise temperature control by acting as a thermostat. This feature, along with the easy-to-use top-mounted control panel with an LED display, adds to its user-friendliness.

The unit is designed with portability in mind, featuring casters and side handles for easy movement between rooms, and comes with an easy-to-install window kit for quick setup. Its noise level is 52 dB, which is relatively quiet, allowing for use in bedrooms without significant disturbance. However, the Energy Efficiency Ratio (EER) is relatively low at 5.8, meaning it may not be the most energy-efficient choice available.

The unit also operates with R410a refrigerant, which is more environmentally friendly. At 56.8 pounds, it is somewhat heavy but manageable with the provided mobility features. Despite some drawbacks in energy efficiency, its ease of use makes it a solid option for those needing an effective, portable cooling solution.

It features decent energy efficiency with a SEER rating of 6.51, which helps avoid significant increases in electricity bills during use. The noise level is low at 45 decibels, aided by Dreo’s patented noise isolation system, allowing for quiet operation during sleep or work.

A notable feature is the true drainage-free system that automatically evaporates excess water, which is especially convenient in humid environments and reduces maintenance. The unit is smart-enabled, offering control via an app, voice assistants like Alexa and Google Home, and a remote, providing flexible and modern ways to adjust comfort. It supports multiple modes—cooling, fan, and dehumidifier—with customizable settings for different weather conditions.

Installation and mobility are designed to be user-friendly, with caster wheels and modular window panels that fit various window types for easy movement and setup. The unit weighs about 57 pounds, which may be heavy for some users despite the wheels. Its cooling capacity is optimized for smaller rooms, and larger spaces may require a more powerful unit. The SEER rating is acceptable but not among the highest for energy savings. The 24-hour timer may be limiting for those needing more advanced scheduling options. This Dreo model is well-suited for users seeking a smart, quiet, and low-maintenance portable air conditioner for small to medium rooms, particularly when easy control and quiet operation are important.
