The BLACK+DECKER Smart Portable Air Conditioner with Heat offers a solid cooling capacity of 14,000 BTU ASHRAE (10,000 BTU DOE), which is suitable for rooms up to 700 sq. ft. This makes it a good fit for medium to large-sized rooms. Additionally, it has a 12,000 BTU heating capacity, allowing it to be used year-round. The unit functions as a dehumidifier and fan, adding to its versatility.

The energy efficiency ratio (SEER) of 6.2 is relatively low, indicating higher energy consumption compared to more efficient models. It's important to note that this model is not Energy Star rated, which means it might not be the most cost-effective option over time for energy savings. The noise level is 54 dB, which is moderate and may be noticeable in quieter environments but should be acceptable for most users. The air conditioner is portable, making it easy to move around as needed.

Additional features include smart connectivity with Wi-Fi, app control, and voice commands via Amazon Alexa or Google Assistant, which add convenience. The 'Follow Me' remote control is another useful feature, allowing for more precise temperature control. The product includes an easy-to-install window kit for setup. Weighing 35 pounds and having compact dimensions, it should be manageable for most people to handle. Assembly is required, which might be a minor inconvenience for some users. This BLACK+DECKER unit is a versatile and convenient option, especially for those looking for a portable and smart-controlled air conditioner with heating capabilities, despite its higher energy consumption.

The Senville LETO Series Mini Split Air Conditioner Heat Pump offers a substantial cooling capacity of 12,000 BTU, making it suitable for cooling medium-sized rooms. One of its standout features is the high Seasonal Energy Efficiency Ratio (SEER) of 20.8, which indicates it operates efficiently and could help reduce electricity bills. The inclusion of a DC Inverter further enhances its energy efficiency and performance consistency.

This model supports voice control through Alexa, allowing for convenient adjustments via app or voice commands from anywhere, which could be appealing to tech-savvy users or those who enjoy smart home integration. Additionally, it serves multiple roles as an air conditioner, heat pump, dehumidifier, and fan, making it versatile for year-round use. The unit operates relatively quietly, which is ideal for bedrooms and living areas where noise can be disruptive.

It does require professional installation, which might add to the initial cost. Although it comes with a comprehensive 5-year warranty on parts and the compressor, labor costs for installation are not covered. The product does not meet Energy Star compliance, which might be a consideration for eco-conscious buyers. Its compact and stylish design allows it to blend into both residential and commercial settings without compromising aesthetics. The package includes necessary installation components, making it convenient, but the pre-loaded refrigerant accommodates only up to 25 ft, which could limit installation flexibility in larger spaces.

The BLACK+DECKER Smart Portable Air Conditioner offers 12,000 BTU cooling power, making it suitable for cooling rooms up to about 550 square feet, which fits well for bedrooms or medium-sized living spaces. It’s a versatile three-in-one unit that not only cools but also dehumidifies and works as a fan, adding extra value. The unit is portable, with manageable dimensions and a weight under 60 pounds, so you can move it between rooms without much trouble. It features a Follow Me remote control that acts like a thermostat, helping maintain a precise temperature where you are, which is pretty handy. Additionally, smart connectivity lets you control it via a mobile app or voice commands through Alexa or Google Assistant, adding convenience if you enjoy tech extras.

Its energy efficiency ratio (SEER) is 5.8, which is on the lower side, and it is not Energy Star certified, so it might use more electricity than some other models. The noise level is around 52 decibels — fairly typical for portable ACs but might be noticeable in very quiet settings like bedrooms at night. Installation is straightforward thanks to the included window kit, making it easier for those who want a simple setup without professional help. The unit has a modest water capacity and features auto water evaporation to reduce manual draining, which helps with maintenance.

This portable air conditioner suits those needing flexible, moderately powerful cooling with smart controls, but if you prioritize top energy efficiency or ultra-quiet operation, this model may not be the best fit.
