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.

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.

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.
