You may be looking for tabu 12 alternatives because your needs differ from the standard 12,000 BTU 115V setup. The Rellytech 18,000 BTU 230V Mini Split offers higher capacity and 230V power, which suits larger rooms. It also provides a 19 SEER2 rating for efficient cooling and heating. However, you might prefer a different voltage, a smaller footprint, or smart connectivity features that this specific model does not highlight.

The 5 alternatives on this list were chosen because their specifications overlap with common mini split requirements. We compared voltage options like 115V and 208-230V to match your existing electrical setup. We also looked at SEER2 ratings ranging from 17 to 21 to find the right balance of efficiency. Some units include Wi-Fi smart control, while others focus on basic reliability. This guide helps you find a unit that fits your space and power constraints without guessing.

Our top pick: Rellytech 18000 BTU 230V Mini Split.

Key differences from the Rellytech

YITAHOME 12000 BTU 115V Mini Split

The YITAHOME unit runs on standard 115V power, making it easier to install in rooms without a dedicated 230V circuit. It offers 12,000 BTU of cooling, which is lower than the Rellytech’s 18,000 BTU, so it suits smaller spaces. You gain Wi-Fi smart control for remote management, a feature the Rellytech does not list. The YITAHOME achieves a higher 20 SEER2 efficiency rating, using less electricity per hour of operation. It is lighter and more compact, weighing just 22 pounds compared to the Rellytech’s 112 pounds. Choose this if you prioritize plug-and-play simplicity and smart features over raw cooling power for a larger room.

COSTWAY 9000 BTU Mini Split

This COSTWAY model also uses 208-230V power, similar to the Rellytech, but delivers only 9,000 BTU of cooling capacity. It has a lower 17 SEER2 efficiency rating, meaning it consumes more energy for the same cooling output. You get a self-cleaning feature that the Rellytech data does not mention, which helps maintain air quality with less manual effort. The unit is significantly lighter at 24.4 pounds, making installation easier. It lacks Wi-Fi connectivity, relying on a standard remote instead. Pick this option if you need reliable basic cooling with self-maintenance and do not require high efficiency or smart app integration.

ROVSUN 9000 BTU 20 SEER2 Mini Split

The ROVSUN split uses standard 115V power, avoiding the need for specialized 230V wiring. It provides 9,000 BTU of cooling, which is half the capacity of the Rellytech, limiting it to smaller rooms. However, it offers a higher 20 SEER2 efficiency rating, reducing energy costs compared to the Rellytech’s 19 SEER2. You get Wi-Fi smart control for remote adjustments, a convenience the Rellytech does not provide. The indoor unit is slightly narrower at 31.9 inches wide. It is designed for quiet operation, making it suitable for bedrooms or offices. Choose this if you want efficient, smart-controlled cooling for a small space without 230V infrastructure.

COSTWAY 9000 BTU Mini Split 21 SEER2

This COSTWAY unit matches the Rellytech’s 208-230V power requirement but offers only 9,000 BTU of cooling, suitable for smaller areas. It boasts a superior 21 SEER2 efficiency rating, using less energy than the Rellytech’s 19 SEER2 model. You gain Wi-Fi smart control for remote monitoring and adjustments, which the Rellytech lacks. The indoor unit is compact at 31.9 inches wide and 12.1 inches tall. It weighs only 19.8 pounds, making it much easier to handle during installation. This model is ideal for users who prioritize high energy efficiency and smart features in a smaller, easier-to-install package with standard voltage compatibility.

Albott 9100 BTU 115V Mini Split

The Albott model runs on standard 115V power, fitting into regular household outlets without special circuits. It provides 9,100 BTU of cooling, significantly less than the Rellytech’s 18,000 BTU, restricting it to small rooms. It achieves a 20.5 SEER2 efficiency rating, which is higher than the Rellytech’s 19 SEER2, offering better energy savings. The unit includes smart features for remote control, a benefit the Rellytech does not list. It is designed for quiet operation, making it appropriate for bedrooms or home offices. Choose this if you need efficient, smart-controlled cooling for a small space and want to avoid the complexity of 230V wiring.

Frequently asked questions

Which alternative offers the highest efficiency rating?

The COSTWAY 9000 BTU Mini Split 21 SEER2 holds the top spot for efficiency among these options. It delivers 21 SEER2, which is higher than the Rellytech’s 19 SEER2 and the YITAHOME’s 20 SEER2. This model requires 230V power and includes Wi-Fi smart control for precise temperature management in medium-sized rooms.

Can I use these mini splits with standard 110V outlets?

Yes, several models support standard 115V outlets, which simplifies installation in rooms without dedicated high-voltage circuits. The YITAHOME 12,000 BTU, ROVSUN 9,000 BTU, and Albott 9,100 BTU units all operate on 115V. The Rellytech and COSTWAY 21 SEER2 models require 230V power instead.

Which unit is best for larger rooms needing more cooling?

The Rellytech 18,000 BTU Mini Split is the strongest choice for larger spaces due to its higher capacity. It provides 18,000 BTUs of cooling power, significantly more than the 9,000 to 12,000 BTU options. Note that this unit requires 230V power and has a 19 SEER2 efficiency rating.

Do these mini splits have smart control features?

Most listed models include Wi-Fi connectivity for remote management. The YITAHOME, ROVSUN, and COSTWAY 21 SEER2 units explicitly feature Wi-Fi smart control. The Rellytech and COSTWAY 17 SEER2 models do not list smart capabilities in their specifications, focusing instead on basic reliability and voltage requirements.

What is the difference between the two COSTWAY models?

The primary difference lies in their efficiency and voltage requirements. The COSTWAY 21 SEER2 model offers higher efficiency and Wi-Fi control but requires 230V power. The other COSTWAY unit provides 17 SEER2 efficiency, lacks smart control, and also uses 230V power, prioritizing basic reliability over advanced features.

Which option is best for small bedrooms or offices?

The ROVSUN 9,000 BTU Mini Split is well-suited for small rooms like bedrooms or home offices. It operates on standard 115V power, includes Wi-Fi smart control, and offers 20 SEER2 efficiency. Its quiet operation and compact 9,000 BTU capacity make it ideal for personal spaces without high cooling demands.

How much does the Rellytech unit weigh compared to others?

The Rellytech 18,000 BTU unit weighs 112 pounds, which is heavier than most smaller capacity models. For comparison, the YITAHOME weighs 22 pounds, the ROVSUN weighs 70 pounds, and the Albott weighs 151 pounds. The weight difference reflects the larger compressor and components needed for higher cooling capacity.
