Mixed Results: Cooling Works, App Frustrating
The first unit never cooled and email support stopped responding after initial contact, though a replacement was eventually provided. The second unit installed easily and cools well as a supplement to existing RV air conditioning on hot days, and works alone on overcast days and at night. It draws significantly less power, which is beneficial for boondocking. The app is unreliable, often losing Bluetooth connection and requiring a power cycle to reconnect, though it allows a lower temperature setting than the remote.
Pros
- + easy installation
- + works well alongside existing units
- + sufficient alone on overcast days and at night
- + draws significantly less power
- + app allows lower temperature setting than remote
Cons
- − first unit never cooled
- − email support stopped responding
- − app frequently loses Bluetooth connection
- − requires power cycle to reconnect
- − not enough to cool RV alone on hot days

12k DC Unit Performs Like a Good 8k AC
This 12k DC air conditioner works, but its cooling feels comparable to a strong 8k window unit. It replaced a 13.5k AC that kept the rig icy cold, and this unit is only okay by comparison. Two units with identical part numbers arrived but were physically different. The included DC cable is handy and well made, yet it drops significant voltage, with the unit running at 11.7 volts on fully charged LiFePO4 batteries. Operation is quiet and power draw ranges from 250 to 800 watts.
Pros
- + quiet operation
- + power use of 250–800 watts
- + handy, well-made DC cable
Cons
- − cooling comparable to a good 8k unit
- − less cold than the replaced 13.5k unit
- − significant voltage drop from included cable
- − identical part numbers but different units

Heater Function Not Working
This 12000 BTU DC air conditioner unit was purchased, but the heater does not work. The heating function fails to operate as expected, which is a significant drawback for a product that includes a heat pump. No other performance details, cooling ability, or installation experience are mentioned. The unit's heating feature is non-functional, which may be a concern for buyers relying on both cooling and heating capabilities.

Efficient Rooftop Heat Pump with Easy Install
This rooftop heat pump performs better than expected and significantly reduces power consumption compared to older units. On a 400Ah battery, it runs for about 10 hours without draining even half the battery, with outside temperatures in the mid-80s and the unit set to 70 inside. Installation is straightforward because everything is pre-wired, and it can be completed in under an hour.
Pros
- + better than expected performance
- + reduced power consumption
- + long runtime on battery
- + easy pre-wired installation
