A portable air conditioner can be a practical solution when you want reliable cooling without installing a permanent window or central AC system. For renters, bedrooms, home offices, apartments, and smaller living spaces, a portable unit offers the flexibility to cool one room when you need it.
The good news is that you don't have to spend a fortune to get useful cooling features. Several portable air conditioners are available for under $300, with options offering cooling, fan, dehumidifying modes, remote controls, timers, sleep settings, and even Wi-Fi connectivity.
I compared seven portable AC units priced below $300, looking at cooling capacity, room coverage, convenience features, portability, installation, and overall value. Here are the models I would consider first.
| Model | Cooling Capacity | Room Coverage | US Price |
| DOMANKI 14,000 BTU | 10,000 BTU SACC | Up to 700 sq. ft. | $289.99 |
| ZAFRO A9047L | 8,000 BTU SACC | Up to 500 sq. ft. | $299.98 |
| BLACK+DECKER BPACT10WT | 5,550 DOE | Up to 450 sq. ft. | $289.99 |
| DOMANKI 12,000 BTU | 8,000 BTU SACC | Up to 500 sq. ft. | $284.14 |
| Shinco 12,000 BTU | 7,500 BTU SACC | Up to 450 sq. ft. | $290.03 |
| BLACK+DECKER BPACT08WT | 5,300 BTU SACC | Up to 400 sq. ft. | $299.99 |
| SereneLife 8,000 BTU Wi-Fi | 8,000 BTU | Up to 350 sq. ft. | $259.90 |

If your priority is maximum cooling power under $300, the DOMANKI 14,000 BTU portable air conditioner is one of the most interesting options on this list.
It is rated at 14,000 BTU using the ASHRAE measurement and 10,000 BTU SACC, with coverage advertised for rooms up to 700 square feet. That makes it particularly appealing for larger bedrooms, living rooms, home offices, and other spacious areas.
The unit combines cooling, fan, and dehumidifying functions. It also includes Turbo Mode, Sleep Mode, a 24-hour timer, child lock, and automatic swing louvers.
One feature I particularly like is the self-evaporating system. Under normal conditions, much of the collected moisture is exhausted through the hose, reducing the need for frequent manual draining. In very humid environments, however, some drainage may still be necessary.
At 48 dB in Sleep Mode, it is also designed to be quieter at night.
Price in the US: $289.99
Best for: Large rooms and buyers who want strong cooling power.

The ZAFRO A9047L stands out if smart-home connectivity is important to you. It offers 12,000 BTU cooling capacity, rated at 8,000 BTU SACC, along with cooling, fan, and dehumidification modes.

It also has four fan speeds, a 24-hour timer, Sleep Mode, and a remote control. Sleep Mode can reduce operating noise to around 47 dB while adjusting the temperature and fan speed for nighttime use.
The self-evaporating design is another useful feature, with the manufacturer stating that it can operate for extended periods without drainage under suitable conditions.
Its compact 12.99 x 14.80 x 23.23-inch design and caster wheels make it relatively easy to move around.
Price in the US: $299.98

The unit measures approximately 14 x 15 x 24 inches and uses caster wheels for easier movement. It also includes a window mounting kit, exhaust hose, hose connector, and drain pipe.
A washable filter is another practical feature because it can be removed and cleaned instead of requiring frequent replacement. The 24-hour timer and remote control also make everyday operation easier.

When comparing portable ACs, don't look only at the large BTU number on the box. The SACC rating is often more useful for comparing portable air conditioners because it reflects cooling performance under standardized conditions.
A higher SACC rating generally indicates greater cooling capability, but you should also consider the manufacturer's recommended room size.
Don't automatically buy the most powerful unit. A portable AC designed for a large room may cost more to operate and isn't necessarily the best choice for a small bedroom.
For smaller rooms, an 8,000 BTU-class unit may be enough. Larger living areas may benefit from a higher-capacity model such as the DOMANKI 14,000 BTU.
Every portable air conditioner on this list requires hot air to be vented outside, normally through a window. Check that the included window kit works with your window type before purchasing.
If you're buying an AC for a bedroom, noise matters. Sleep Mode and lower noise ratings can make a significant difference, particularly for light sleepers.
A portable AC that also works as a dehumidifier can be especially useful in humid climates. Removing excess moisture can make a room feel more comfortable even when the temperature hasn't changed dramatically.
For large rooms, I would look at the DOMANKI 14,000 BTU because of its higher cooling capacity and advertised coverage.
For smart-home features, the ZAFRO A9047L is the more interesting choice thanks to app, Alexa, and Google Home compatibility.
For overall value, the BLACK+DECKER BPACT10WT offers a strong balance of cooling, portability, simple controls, and useful features.
If you need something for a medium-sized room, the DOMANKI 12,000 BTU is a compelling option.
For a smaller bedroom and lower budget, the SereneLife 8,000 BTU Wi-Fi provides useful features at $259.90.
You can find several capable portable air conditioners for under $300, but the best choice depends on your room size and the features you actually need.
My top pick for larger spaces is the DOMANKI 14,000 BTU, while the BLACK+DECKER BPACT10WT is a strong all-around option for everyday home cooling. The ZAFRO A9047L is particularly appealing if smart-home control matters to you, while the SereneLife 8,000 BTU makes sense for shoppers looking for a more affordable option.
Before buying, check the current price, SACC rating, recommended room size, window compatibility, and noise level. A portable AC works best when its cooling capacity matches the space you are trying to cool.
