The Humhold 14000 BTU Portable Air Conditioner is a robust solution for cooling spaces up to 700 square feet, making it ideal for larger rooms like living rooms, bedrooms, and offices. Its 14000 BTU cooling capacity ensures efficient temperature control between 61°F and 88°F, and the unit also functions as a dehumidifier and a fan, providing versatile home climate control.

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.

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 Whynter Portable Air Conditioner ARC-14S is a solid choice for cooling rooms up to 500 square feet, with a strong 14,000 BTU cooling capacity. It uses a dual-hose system that helps cool more efficiently and has a built-in dehumidifier that can remove up to 71 pints of moisture per day, which is great if you want to reduce humidity as well as temperature. Noise-wise, it operates quietly at about 51 decibels on low, making it suitable for bedrooms or living spaces where a quieter environment is preferred.

The unit offers three modes—cool, dehumidify, and fan—with adjustable fan speeds and a thermostat for temperature control between 61°F and 89°F. While it’s not Energy Star certified, it has a decent energy efficiency ratio (EER) of 7.69, meaning it balances power use and cooling fairly well, though it might use more electricity than some newer models. Weighing 73 pounds, it’s portable but somewhat heavy, so moving it frequently might be a bit challenging.

Installation requires a window vent kit, which is included, and maintenance is straightforward thanks to washable filters and an auto-drain function that handles condensate automatically in most conditions. Controls include a remote for convenience. This unit is well-suited for those needing effective cooling and dehumidifying in medium-sized rooms, who don’t mind a bit of weight and want quiet operation. However, if energy efficiency is a top priority or if you need a lighter unit, there might be better options available.
