ZERO BREEZE Mark 3 12V to 48V Converter

The ZERO BREEZE Mark 3 12V to 48V Converter Delivers High-Efficiency Power So That You Stay Cool Anywhere You Park, Camp, or Work

The ZERO BREEZE 12V to 48V Converter is the missing link between your Mark 3 Portable AC and the DC power sources you already rely on every day.

Whether that's a deep-cycle battery bank in your RV, a solar-charged off-grid system, or a mobile worksite power supply, this compact booster module takes 12V–36V DC input and steps it up to a steady 48V output, so that your Mark 3 runs reliably without demanding a dedicated wall outlet.

For homeowners building backup power resilience, RVers chasing comfortable temperatures on the road, off-grid adventurers living independently from the grid, and mobile business owners who need climate control wherever the job takes them, this converter is the practical bridge between "I have power" and "I have the right power."

Rated for 600W of continuous output at a stable 48V, this converter is sized correctly for the Mark 3's real-world power draw. There's no guesswork and no underpowered workaround, just a dedicated module engineered to match the unit's demands. When you're depending on cool air during a heat wave, a long highway stretch, or a demanding job, that headroom matters.

Outbound Power carries this accessory because it solves a real problem elegantly: portable AC units are power-hungry, and not every power source speaks their language. This converter translates.

A Booster That Matches Your Mark 3's Power Needs Exactly

Rated for 600W of continuous output at a steady 48V, this converter gives your Mark 3 the right amount of power. No guesswork, no underpowered shortcuts, just a module built to keep your cooling running strong.

One Converter Works With Almost Any Battery System You Have

Whether you run a 12V, 24V, or 36V setup, this converter handles it all. As your power system grows or changes over time, this booster keeps working without needing a replacement or upgrade.

Pick the Cable Type That Fits Your Power Source Best

Choose Eye Terminals for a secure bolt-on connection if you run 12V batteries, or Anderson Terminals for quick-connect convenience on 24V–36V systems. Either way, you get hardware matched to your exact setup.

A Short Cable Keeps Your Setup Neat and Tidy

The 1.2-meter cable runs cleanly from the converter block to the D20 connector. In tight RV cabins or mobile workspaces, that shorter length means less clutter and an easier, cleaner installation overall.

Built Just for the Mark 3, Not a Generic Fit

Unlike universal converters that are made for general use, this one is engineered specifically for the Mark 3's power needs. That means steadier performance, less overheating, and a part that actually belongs there.

Everything You Need Comes Included in the Box

You get the 48V converter block plus your chosen XT90 input cable, ready to connect. There's no separate shopping trip or guessing which parts you need to complete your power setup.

Made for Users Who Know Their Way Around DC Power

This converter suits RV owners, off-grid builders, and field techs comfortable with DC wiring. With proper fusing and careful setup, it becomes a dependable, long-term part of your power system.
