The DOMANKI 12,000 BTU Portable Air Conditioner is a well-rounded option for cooling spaces up to 500 sq.ft. Its strong cooling capacity, combined with multiple functions like dehumidification and fan modes, make it versatile for various settings such as offices, campervans, and temporary spaces. The unit is energy efficient with an EER of 7.2, though this is on the lower side compared to some other models.

It operates quietly at 52 dB, making it suitable for bedrooms and workspaces where noise is a concern. Portability is a major advantage, thanks to its compact design and casters, allowing easy movement between rooms. The included remote control and digital display enhance usability, even for those unfamiliar with smart gadgets. Maintenance is straightforward with a removable and washable air filter that helps maintain air quality and extends the unit’s lifespan.

However, it is relatively heavy at 55 pounds and might be cumbersome for some users to move. The air conditioner also uses R-32 refrigerant, which is more environmentally friendly. Though efficient, the SEER of 7.2 indicates it might not be the most energy-saving option available. It comes with a comprehensive installation kit, making it user-friendly right out of the box.

The BLACK+DECKER Smart Portable Air Conditioner offers a cooling capacity of 14,000 BTU (ASHRAE)/10,000 BTU (DOE), making it suitable for rooms up to 700 sq. ft. This unit is quite powerful and should keep larger spaces cool. It also boasts a three-in-one functionality, working as an air conditioner, dehumidifier, and fan, which adds to its versatility.

The 'Follow Me' remote control feature is beneficial for precise temperature control based on the remote's location, enhancing user convenience. Additionally, the unit supports smart controls through Wi-Fi, allowing remote operation via a mobile app or voice commands using Amazon Alexa or Google Assistant, which is a nice modern touch for tech-savvy users.

The installation kit simplifies setup, and the washable filter reduces maintenance costs over time. However, the air conditioner's Energy Efficiency Ratio (EER) of 6.2 is relatively low, meaning it might not be the most energy-efficient option available, potentially leading to higher electricity bills. With a noise level of 54 dB, it's relatively quiet but may still be noticeable in a quiet room. Despite being portable, its weight of 62.4 pounds can make it slightly cumbersome to move frequently. In conclusion, this BLACK+DECKER model is ideal for users needing a powerful and versatile air conditioner with modern smart features, though it may be less appealing to those prioritizing energy efficiency and ease of portability.

The smart and sleep modes, along with the 24-hour timer, help in saving energy and maintaining comfort. The noise level is less than 48dB in sleep mode, which should be quiet enough for most users during nighttime operation. Portability is enhanced by 360° wheels and side handles, making it easy to move the unit between rooms.

The LED display and remote control offer convenient operation from up to 23 feet away, though the reliance on a remote might be a downside if it's misplaced. Maintenance is simplified with a self-evaporation system, although in very humid environments, manual draining will be required. The removable, washable filter is a handy feature for keeping the unit running efficiently. Installation is straightforward with the included window sealing kit and exhaust hose. This air conditioner is a solid choice for those needing a versatile and portable cooling solution, particularly in larger spaces.
