The Mark 3 Air Conditioner is built for people who actually live, sleep, and work outdoors — not just sit next to a power point.

This is true portable cooling. No bulky compressor. No complicated install. Just fast, quiet relief when the heat becomes the problem.

Plug it in. Cool down. Get on with it.

Why the Mark 3 Air Conditioner is different

Most “portable” air conditioners aren’t portable at all.
They rely on large, heavy compressors that make moving and setting up a hassle.

The Mark 3 Air Conditioner uses a custom 48V micro-compressor weighing just 3.9 lb, delivering real portability with 5,280 BTU of cooling power. That means you get serious cooling without hauling oversized gear.

It’s cooling designed for camps, vans, boats, rooftops, and remote setups.

Mark 3 Air Conditioner cooling performance

With 5,280 BTU of cooling power, the Mark 3 Air Conditioner is built to cool personal spaces effectively, even in demanding outdoor conditions.

Whether you’re cooling a tent, van, rooftop setup, or work area, this output gives fast relief without the constant roar of traditional units.

In Sleep Mode, noise drops to 46 dB, making it suitable for overnight use when quiet matters most.

Thermostat control with the Mark 3 Air Conditioner

Everyone experiences heat differently.
That’s why the Mark 3 Air Conditioner includes full thermostat control.

You can freely adjust:

• Cooling

• Heating

• Dehumidifying

Set it once and forget about the temperature altogether. The system manages itself so you can focus on resting, working, or sleeping comfortably.

7 operating modes built for outdoor use

The Mark 3 Air Conditioner adapts to changing conditions with seven dedicated modes:

• Rocket

• Cool

• Sleep

• Fan

• Dry

• Care

• Heating

From rapid cooldown after a long day in the sun to gentle airflow overnight, each mode is designed to match real outdoor use — heat, humidity, and temperature swings included.

True portability of the Mark 3 Air Conditioner

This unit is designed to move easily, not stay parked.

• Main unit weight: 22 lb / 10 kg

• Main unit volume: 1,525 in³ (≈ 25 L)

• Set-up time: Plug & cool in 60 seconds

The cabin footprint is roughly the size of a 25 L travel duffel, making it practical for tight spaces where traditional AC units simply won’t fit.

Mark 3 Air Conditioner power options

The Mark 3 Air Conditioner runs on a 48V cooling system, designed for stable, efficient operation.

Power can be supplied in multiple ways:

• Mark 3 Smart Battery (sold separately)

• AC adapter

• Solar charging (via Mark 3 battery)

• 12V vehicle charging (via Mark 3 battery)

This flexibility lets you tailor your setup for camping, vehicle installs, or off-grid use without being locked into one power source.

Designed to work with the Mark 3 battery system

When paired with the Mark 3 Smart Battery, the Mark 3 Air Conditioner becomes a complete off-grid cooling system.

Key battery features (battery sold separately):

• 1022Wh capacity

• 12–60V DC input range

• Built-in 500W MPPT for solar charging

• 0–80% charge in 2 hours

• Supports charging while discharging

Multiple batteries can be connected to extend runtime — double, triple, or more depending on your needs.

How long can the Mark 3 Air Conditioner run?

Runtime depends on battery configuration and mode.

As a general guide:

• Single battery: Short cooling sessions or light use

• Two batteries: Around 7 hours in sleep mode

• Multiple batteries: Extended cooling for long nights or extreme heat

This modular approach lets you scale your setup instead of over-buying power you don’t need.
