Our top pick: Rellytech 18000 BTU 230V Mini Split.
How these alternatives differ
YITAHOME 12000 BTU 230V Mini Split
The YITAHOME 12000 BTU model targets smaller rooms with a focus on smart connectivity. It includes built-in Wi-Fi, allowing you to control the unit via an app, a feature the Rellytech lacks. While it runs on the same 230V power, its efficiency is lower at 17 SEER2 compared to the Rellytech’s 19 SEER2. It also has a much smaller indoor unit footprint, measuring only 7.9 inches deep. If you need precise remote management for a compact space and do not require maximum efficiency, this is a practical choice. It sacrifices raw cooling power for easier digital integration.
COSTWAY 24000 BTU 230V Mini Split
The COSTWAY 24000 BTU unit offers significantly higher cooling capacity for larger areas. It delivers 24,000 BTUs, which is nearly 33 percent more than the Rellytech’s 18,000 BTU output. This makes it suitable for spaces exceeding 1,250 sq. ft. It operates on 230V power and has a comparable efficiency rating of 18.5 SEER. However, it lacks the smart Wi-Fi controls found in other alternatives. The indoor unit is also wider, measuring 44.5 inches. You should choose this model if your primary goal is maximum cooling power for a large room rather than smart features or compact dimensions.
Senville LETO 24K BTU 230V Mini Split
The Senville LETO 24000 BTU split provides high capacity with integrated Alexa support. Like the COSTWAY, it delivers 24,000 BTUs for large spaces, but it adds voice control compatibility. It runs on 208/230V power, matching the Rellytech’s voltage requirements. The indoor unit is notably narrower at 12.6 inches wide, though it is taller at 27.6 inches. This design allows it to fit in tighter wall spaces. If you need strong cooling for a large area and want to control the temperature using voice commands, this model offers a unique advantage over the standard remote-only Rellytech system.
ROVSUN 12000 BTU 230V Mini Split
The ROVSUN 12000 BTU model prioritizes energy efficiency and smart control. It achieves a 20 SEER2 rating, which is higher than the Rellytech’s 19 SEER2, making it more efficient for medium-sized rooms. It includes Wi-Fi connectivity for app-based management, a feature the Rellytech does not offer. It operates on 230V power. The indoor unit is compact, measuring 31.9 inches wide. You should pick this alternative if you value lower energy consumption and digital convenience over the higher raw cooling capacity of the Rellytech. It is ideal for users who want efficient, smart-controlled cooling in a moderate space.
COSTWAY Blast Pro 18000 BTU 230V
The COSTWAY Blast Pro 18000 BTU matches the Rellytech’s cooling capacity but improves on efficiency and connectivity. It offers a 20 SEER2 rating, which is one point higher than the Rellytech’s 19 SEER2. It also includes Wi-Fi smart control, allowing for app-based operation. It runs on 230V power. The indoor unit is slightly wider at 35.8 inches but has a similar depth. This model is a better fit if you want the same cooling power as the Rellytech but prefer higher energy efficiency and the ability to manage the unit remotely via a smartphone application.

Frequently asked questions
Which alternative offers the highest efficiency rating?
The ROVSUN 12000 BTU and COSTWAY Blast Pro 18000 BTU models both lead with a 20 SEER2 rating. This high efficiency means lower energy consumption during operation. The Rellytech follows closely at 19 SEER2. Higher SEER2 values indicate better cooling performance per watt of electricity used.
Do these mini splits require 230V power?
Yes, all listed alternatives operate on 230V power. This includes the Rellytech, YITAHOME, COSTWAY, Senville, and ROVSUN models. You need a dedicated 230V circuit for installation. Standard 120V household outlets are not compatible with these high-capacity units.
Which models include Wi-Fi smart control?
The YITAHOME, ROVSUN, and COSTWAY Blast Pro models feature built-in Wi-Fi. These allow you to control the unit via a smartphone app. The Rellytech, COSTWAY standard, and Senville models do not list smart connectivity in their specifications. You will need to use the physical remote for those.
What is the largest cooling capacity available?
The largest capacity is 24,000 BTU. Both the COSTWAY and Senville models provide this high output. They are designed for large rooms or open spaces. The other options range from 12,000 to 18,000 BTU for smaller areas.
How do the indoor unit dimensions compare?
Dimensions vary significantly by model. The Senville indoor unit is notably taller at 27.6 inches. The Rellytech is wider at 39.6 inches. The YITAHOME is the most compact at 31.2 inches wide. Check your wall space against these specific width and height measurements before buying.
Are any units suitable for Alexa integration?
The Senville LETO 24K BTU model explicitly supports Alexa integration. This allows voice control through compatible Echo devices. Other models like the ROVSUN and YITAHOME offer app control but do not list specific smart speaker compatibility in their specs. Check the app store for additional voice commands.
Which model is best for small rooms?
The YITAHOME 12000 BTU model is best for small rooms. It provides sufficient cooling for smaller spaces while offering smart Wi-Fi control. The ROVSUN 12000 BTU is another solid option for medium-sized rooms. Larger units like the 24,000 BTU models would be overkill for small areas.
Do any models lack smart features?
The Rellytech 18000 BTU and the standard COSTWAY 24000 BTU models lack listed smart features. They rely on traditional remote controls and basic functionality. If you need app management or Wi-Fi connectivity, you should choose the YITAHOME, ROVSUN, or COSTWAY Blast Pro instead.
