Nomadic Cooling Helix X2 RV Air Conditioner (12/48V) is the compact member of our X-Series — built for crews who want steady comfort, real remote control, and more roof room for solar without committing to an oversized battery bank. An efficient PWM compressor modulates instead of hard cycling, so your 12V/48V RV air conditioner holds temperature smoothly with less draw. Pair it with Helix to add scenes, schedules, and true remote access on phone, tablet, or watch — pre-cool before you return and keep pets comfortable while you’re out.

With its compact design and low power consumption, this RV air conditioner is easy to install (fitting a standard 14" x 14" roof opening) and fits seamlessly into your off-grid lifestyle. It uses only a fraction of the power compared to a standard 120-volt AC unit, so with a sufficiently-sized battery bank, you can enjoy cool comfort in your RV all day and night without worrying about running out of power. Because it doesn't require an inverter, there is no conversion loss from changing DC power into AC power just to run the air conditioner.

But the benefits don't stop there. You'll love the quiet operation of the Nomadic Cooling X2 RV air conditioner - it uses a brushless internal fan and variable-speed compressor, using pulse width modulation (PWM) technology to ramp its power use up or down as needed. 

Don't let the power needs of traditional RV air conditioners hold you back from exploring the great outdoors. Upgrade to the energy-efficient, quiet, Nomadic Cooling Helix X2 RV Air Conditioner (12/48V), and take your off-grid adventure to the next level.

Eco Mode vs Full AC Mode

ECO Mode should be the default operation type on a Nomadic Cooling air conditioner. Full AC Mode should only be used for short periods of time for maximum cooling, as powerful mode has increased consumption of energy.
