Both are designed for similar room sizes, but they approach the task of keeping you cool in fundamentally different ways. This comparison will help you cut through the noise and decide which unit is your perfect match.

We’ll explore their cooling power, unique features, user experiences, and overall value. By the end of this detailed review, you’ll have a clear picture of what makes each unit tick and how they stack up against each other, so you can make an informed decision that leads to sweet, cool relief. Let’s get started by looking at a quick overview.
## In-Depth Look: Kenmore KM8K
The Kenmore KM8K-R 8,000 BTU Window Air Conditioner is a classic solution for cooling medium-sized rooms. Window air conditioners have been a staple in homes for decades, and for good reason. They are generally very efficient, quiet once installed, and take up no floor space. The Kenmore KM8K is designed to tackle rooms up to 350 square feet, making it a solid choice for bedrooms, home offices, or living areas that struggle to stay comfortable during hot weather. Its 8,000 BTU rating is well-suited for this square footage, promising robust cooling power.
This unit boasts a variety of features aimed at providing flexible and convenient comfort. The multi-mode operation is a standout, offering Sleep, Auto, and Eco modes alongside standard Cooling. Sleep mode is designed to gradually adjust the temperature and fan speed for a more comfortable night’s rest without sudden chills. Auto mode lets the unit intelligently manage its operation to maintain your set temperature, while Eco mode conserves energy by cycling the compressor and fan off periodically. Three fan speeds allow for further customization of airflow. Control is made simple with an easy-to-use digital touch panel and a handy remote control, so you can adjust settings without leaving your couch.
Energy efficiency is also a key selling point, with a CEER of 10.9. This metric indicates how effectively the air conditioner uses energy to cool, translating to lower utility bills and a more environmentally friendly operation. This is a significant consideration for many buyers, as air conditioners can be energy-hungry appliances. Furthermore, the Kenmore KM8K comes with practical features like a washable filter, which is both cost-effective and better for air quality by capturing dust and particles. The auto-restart function is a lifesaver during unpredictable weather, ensuring that your settings are restored after a power outage, so you don’t have to manually reset the unit.

## In-Depth Look: BLACK+DECKER Portable Air Conditioner
The BLACK+DECKER Portable Air Conditioner, 8,500 BTU, offers a different approach to climate control. Unlike window units, portable air conditioners sit on the floor and connect to a window via a hose for exhaust. This design offers a significant advantage: portability. You can move it from room to room as needed, making it a versatile solution for apartments, dorms, or homes where window installation might be difficult or undesirable. This particular model is rated for rooms up to 350 sq. ft., a similar capacity to the Kenmore KM8K, and its 8,500 BTU rating (with a 5,100 BTU SACC rating, which is a more realistic measure for portable units) ensures it can handle those spaces effectively.
A key feature of this BLACK+DECKER unit is its three-in-one functionality. It not only cools but also acts as a dehumidifier and a fan. This means it can tackle multiple environmental challenges, helping to manage humidity levels, circulate air, and provide cooling, all from a single appliance. This all-in-one capability can be particularly appealing if you’re looking to address various comfort issues. The unit utilizes R-32 refrigerant, which is known for being more environmentally friendly and energy-efficient compared to older refrigerants. This aligns with a growing consumer demand for sustainable products.
Control is designed to be user-friendly. It features a top-mounted LED display and control panel, making it easy to adjust settings like temperature, fan speed, and mode without bending down. The inclusion of a full-function remote control further enhances convenience, allowing you to manage all the unit’s features from anywhere in the room. This is a common desire for many consumers seeking effortless operation. The portability is further enhanced by wheels, allowing you to easily roll the unit between rooms. While it requires window venting, the setup is generally considered straightforward for a portable unit.
### BLACK+DECKER Portable Air Conditioner: Pros and Cons
Pros:
- Portability: Easily move the unit between rooms thanks to its design and wheels.
- 3-in-1 Functionality: Acts as an air conditioner, dehumidifier, and fan for comprehensive climate control.
- Eco-Friendly Refrigerant: Uses R-32 refrigerant for better environmental impact and efficiency.
- Convenient Controls: Top-mounted panel and full-function remote make operation easy.
- Suitable for Various Spaces: Ideal for apartments, dorms, offices, and bedrooms.
- Fast Cooling: Customer reviews indicate it cools rooms down quickly.
Cons:
- Window Venting Required: Like most portable ACs, it requires a window kit and hose for exhaust.
- Noise Level: Some users report it can be a bit loud, which is a common characteristic of portable units due to the compressor and fan being in the same room.
- Potential Fit Issues: One user mentioned the window panel was slightly short for their windows, requiring a workaround.
- SACC Rating: The 8,500 BTU rating is accompanied by a 5,100 BTU SACC rating, which is important to note for accurate cooling capacity expectations in portable units.
### Customer Reviews: BLACK+DECKER Portable Air Conditioner
Here’s a glimpse into what customers are saying about the BLACK+DECKER Portable Air Conditioner:
“I bought this for my apartment living room and this unit cools down the room in no time! Easy to install, it’s quiet and works amazing!”
This positive review emphasizes rapid cooling, ease of installation, and quiet operation.
“I bought this for my son’s room. It definitely makes the room COLD! Pretty easy to install. My son’s room size is 12×12. I don’t feel it’s great for being portable since it does need to be installed through a window.”
This customer highlights its effectiveness in cooling but questions its true “portability” due to the need for window venting. This is a common observation for portable units.
* “Bought two of these units after our top floor air conditioner went out as a supplement until we can have the main unit repaired. Worked marvelously for both upstairs bedrooms where we sleep so it worked perfectly as advertised. Very easy to move around and set up as the wheels work nicely. Only reason for 4 and not 5 stars was that the sliding panel that goes in the window was just short for both of our windows but we found a workaround. A few reviews complain that the unit is loud and I believe…”
This reviewer found the units effective as a supplement, praised their mobility, but noted a minor issue with the window kit fit.
### BLACK+DECKER Portable Air Conditioner: Best For
The BLACK+DECKER Portable Air Conditioner is a great option for:

## Head-to-Head Comparison
Now that we’ve explored each unit individually, let’s put them side-by-side to see how they truly compare on key aspects.
### Cooling Performance and Capacity
The BLACK+DECKER Portable Air Conditioner boasts a slightly higher BTU rating at 8,500, compared to the Kenmore KM8K’s 8,000 BTU. However, it’s important to consider the SACC (Seasonally Adjusted Cooling Capacity) rating for portable units, which is 5,100 BTU for the BLACK+DECKER. Window ACs are generally more efficient at delivering their stated BTU output directly into the room. Both are rated for rooms up to 350 sq. ft. Customer reviews suggest both units cool effectively within their intended room sizes. The Kenmore KM8K, as a window unit, might deliver its cooling power more directly and efficiently into the space.
### Installation and Setup
This is where the two units diverge significantly. The Kenmore KM8K is a window air conditioner, meaning it requires installation into a window frame. This typically involves securing the unit with side panels and ensuring a snug fit to prevent air leaks. While often straightforward, it does require some assembly and might need tools. The BLACK+DECKER Portable Air Conditioner requires connecting an exhaust hose to a window using a provided kit. While this doesn’t involve mounting anything permanently in the window frame, it does mean the unit is tethered to a window and requires venting. Many users find portable AC setup easier than window AC installation, but both have their steps. One user noted the BLACK+DECKER’s window panel was a bit short, which can sometimes be a minor hurdle with portable AC kits.
### Portability and Flexibility
This is the BLACK+DECKER Portable Air Conditioner’s clear win. Designed to be moved, it features wheels and a hose that can be disconnected (though the hose needs to be reconnected for use). You can easily shift it from a bedroom to a living room, offering flexibility that the Kenmore KM8K simply cannot match. The Kenmore KM8K is a fixed installation; once it’s in the window, it stays there for the season. This makes the BLACK+DECKER the superior choice for renters or those who need cooling in multiple locations. If portability is a key concern, consider exploring options in our Best Portable Air Conditioner For Small Room guide.
### Features and Functionality
The Kenmore KM8K excels with its multi-mode operation, including Sleep, Auto, and Eco modes, offering a sophisticated approach to comfort and energy saving. The washable filter is a practical, long-term benefit. The BLACK+DECKER Portable Air Conditioner stands out with its 3-in-1 functionality, combining AC, dehumidifier, and fan modes. This versatility can be very attractive if you face issues beyond just heat. Both units offer convenient digital controls and remote access, ensuring ease of use. The BLACK+DECKER’s use of R-32 refrigerant is a nod towards environmental consciousness.
### Energy Efficiency
The Kenmore KM8K has a specified CEER of 10.9, which is a good indicator of its energy efficiency. This metric is directly comparable and suggests it’s quite efficient for a window unit. While the BLACK+DECKER Portable Air Conditioner doesn’t explicitly state its CEER, its use of R-32 refrigerant hints at a focus on efficiency. However, portable air conditioners, by their nature, can sometimes be less energy-efficient than window units due to factors like heat leakage from the exhaust hose and the compressor being in the same room. For energy-conscious buyers prioritizing raw efficiency, the Kenmore KM8K likely has a slight edge.
### Noise Levels
Customer feedback on noise can be mixed for both. One reviewer found the Kenmore KM8K’s compressor to be very quiet, but the fan a bit noisy. For the BLACK+DECKER Portable Air Conditioner, one review noted it was “quiet,” while another acknowledged that “a few reviews complain that the unit is loud.” Generally, portable ACs tend to be noisier than window units because the compressor is located inside the room, whereas in a window unit, it’s mostly outside. If absolute quiet is paramount, both might require some tolerance, or further research into specific noise ratings.
### Value and Price
While exact pricing fluctuates on Amazon, both units generally fall into a similar mid-range price bracket for their respective types and capacities. The value proposition differs based on your needs. If you need a fixed, highly efficient cooling solution for a specific room and can install a window unit, the Kenmore KM8K offers excellent value. If flexibility, multi-functionality, and avoiding window installation are your priorities, the BLACK+DECKER Portable Air Conditioner provides strong value despite potential slight trade-offs in raw energy efficiency or noise.
## Frequently Asked Questions
### Q: Which unit is better for a small apartment where I can’t make permanent modifications?
A: The BLACK+DECKER Portable Air Conditioner is the clear winner here. Its portable nature means you don’t need permanent window installations, making it ideal for renters or those who want to avoid modifying their living space.
### Q: I have a dedicated window space in my bedroom. Which unit should I choose?
A: For a dedicated window space, the Kenmore KM8K is an excellent choice. Window ACs are often more energy-efficient and don’t take up floor space, making them a great fit for a permanent setup.
### Q: My room gets very humid. Which unit offers better dehumidification?
A: The BLACK+DECKER Portable Air Conditioner has a dedicated dehumidifier mode, making it a more versatile option if humidity is a significant concern in addition to heat. While the Kenmore KM8K does dehumidify as part of its AC function, the dedicated mode on the BLACK+DECKER might offer more control.
### Q: How much noise can I expect from each unit?
A: Both units have mixed reviews regarding noise. Generally, portable ACs like the BLACK+DECKER tend to be louder than window ACs like the Kenmore KM8K because the compressor is located within the room. However, customer experiences vary, and factors like room acoustics play a role. If minimizing noise is critical, further research into decibel ratings might be necessary for both models, and perhaps looking at units specifically designed for quiet operation, such as some found in our Best Portable Air Conditioner For Bedroom guide.
### Q: Which unit is more energy-efficient?
A: The Kenmore KM8K has a higher CEER rating (10.9) which is a strong indicator of energy efficiency for window units. While the BLACK+DECKER Portable Air Conditioner uses eco-friendly R-32 refrigerant, portable units can sometimes be less efficient overall than well-installed window units due to heat transfer through the exhaust hose. For pure energy efficiency, the Kenmore KM8K likely has an edge.
## Final Verdict: Which One Should You Choose?
The decision between the Kenmore KM8K and the BLACK+DECKER Portable Air Conditioner boils down to your specific needs and living situation. Both are competent coolers for rooms up to 350 sq. ft., but they cater to different priorities.
If you have a suitable window and want a highly efficient, space-saving cooling solution that you don’t plan on moving, the Kenmore KM8K is a fantastic choice. Its established brand reputation, solid energy efficiency rating, and practical features like multiple modes and a washable filter make it a reliable performer for a dedicated space. It’s the classic, no-fuss way to keep a room cool and comfortable, and if you’re looking for a window unit, our Frigidaire 8,000 BTU Window Air Conditioner Review might also be of interest.
On the other hand, if flexibility is key, you’re renting, or you simply prefer not to install a unit in your window, the BLACK+DECKER Portable Air Conditioner is likely the better option. Its portability, 3-in-1 functionality (AC, dehumidifier, fan), and use of R-32 refrigerant offer significant versatility and modern features. While it requires venting, the ability to move it between rooms or store it away during colder months is a major advantage. It’s a great all-around performer for those who need cooling solutions that can adapt to their lifestyle. You can find more comparisons in our Portable Air Conditioners Review 2026.
Ultimately, there’s no single “best” for everyone. Consider whether you value fixed efficiency and space-saving (Kenmore KM8K) or adaptability and multi-functionality (BLACK+DECKER Portable Air Conditioner) most. Both offer effective cooling for medium rooms, so choose the one that best fits your lifestyle and living space.
