This SubZero Portable AC is a lot more powerful than you would think. It puts out a strong breeze and keeps me cooler on even the hottest of days. I bought it to use for my trips to the Orlando theme parks, and it has not disappointed at all. This AC has three speeds, all of which provide a good amount of cool air, and it is easy to direct the air where you want it. The battery lasted the whole day, and it is easy to charge on the go, if needed. I really like that I can clip it on to my shirt or at my waist, or I can clip it on my lanyard and wear it around my neck. This powerful little AC is a total game changer for those hot and humid days wherever you may be!

The Engineering Behind Subzero

Most cooling products cool the air around you. Subzero cools you. Its 360° internal ventilation system works inside your clothing, bringing the feel of air conditioning wherever you go.

85% More Cooling Power

The 60-blade airflow engine and 5 directional outlets generate 85% more concentrated airflow than standard cooling devices, delivering the kind of full-body cooling that nothing you clip to your collar can match.

Cools Your Whole Body, Not Just Your Face

A 360° diffused airflow circulates inside your shirt, activating your body's natural cooling response. Heat is pulled away from your core, not just your skin. That is the difference between a cooling device and a personal AC.

Silent Enough to Wear Anywhere

At 36dB or less (quieter than a library) Subzero runs without drawing attention. Wear it at your desk, in class, on a commute, or at an outdoor event without anyone noticing.

10,000+ People Who Stopped Sweating Through Their Day

Whether you're on a job site, stuck in a hot office, or just trying to get through summer without overheating, SubZero is how you stay comfortable without thinking about it.

Does it work in extreme heat?

Yes, and it performs best when temperatures are at their highest. The hotter the conditions, the more the body sweats, and the more efficiently Subzero works. By accelerating sweat evaporation across the torso, it draws heat away from the body more effectively in extreme heat than in mild conditions.

How does Subzero work?

Subzero clips to your waist and channels a 360° airflow inside your shirt. That airflow accelerates sweat evaporation across the torso, continuously pulling heat away from the body. It also clips to bag straps, chair backs, and belt loops for cooling wherever you need it.

How long does it last?

Subzero delivers up to 6 hours of continuous cooling on a single charge. USB-C charging brings it back to full in just over an hour.

Is Subzero rechargeable?

Yes. It charges via USB-C, and the cable is included in the box.
