Backup DC power keeps the compact inflator working without a charged pack, on everything from camper van and RV tires to travel trailers.
DALLAS, Nov. 13, 2026 /PRNewswire/ — Camper van and RV owners who already keep 20V cordless tool batteries on board can now use them to air up their tires too. The new HyperFlow 35 portable tire inflator from Wolfbox, a leader in automotive electronics and off-road gear, runs on those packs, switches to DC power when a battery runs low and delivers up to 80 PSI for high-pressure RV and trailer tires.
Doing away with the need for a separate, dedicated inflator battery, the HyperFlow 35 is the handy, essential tool that every driver needs within easy reach, for more assurance that they won’t get stranded on the road.
Air Up Anywhere With the Battery You Already Have
Tire trouble can show up anytime: in the driveway before a trip, at a campsite or somewhere along the journey. For Class B RV owners, who have little storage and aren’t always near a garage, many other portable inflators come with a catch: a separate battery to charge and pack, limited or missing DC power, or not enough pressure stability for bigger tires. The HyperFlow 35 was designed to get around all three.
Wolfbox’s solution is to let drivers take advantage of what they likely already own. The new tire inflator works with 20V batteries from major brands such as DEWALT and Milwaukee, so that there’s no dedicated inflator battery to keep track of. Its compact body is easy to tuck away in a van or RV, where every inch counts.
Enough Muscle for the Whole Rig
The HyperFlow 35’s small size doesn’t limit its capability. It delivers stable airflow while pumping up to 80 PSI and is suited to larger van, RV and travel-trailer tires, including Load Range E. That sets it apart from small emergency inflators built mainly for passenger cars.
It inflates a 40-inch tire from 10 to 37 PSI in about four minutes, so checking tires before a trip doesn’t have to take half the morning.
Built-in cooling fans keep heat down, and the inflator can run continuously for up to 40 minutes under normal temperature conditions. That’s enough time to work several van tires in one session, or to top off pressure after a long drive on a hot day.
The HyperFlow 35 also maintains tire pressure accuracy within ±1.5 PSI and supports high-altitude calibration, so readings stay trustworthy as temperatures and elevations change along the route.
The DC backup is there for the moment a battery runs out. By using supplied battery clips that draw DC power directly from the vehicle’s battery, travelers can still inflate a tire without a charged pack, which takes some of the worry out of longer trips and roadside emergencies.
Ready for Vehicles, Outdoors and Home
Not just for vans and RVs, the HyperFlow 35 works well on car and SUV tires too, making it an ideal tire inflator for anyone who uses 20V tool batteries. Multiple nozzle options enable it to inflate bike tires, air mattresses, balls and other common travel items, making it just as useful in the garage and at home as on the road or at the campsite.
Now available in the US, the Wolfbox HyperFlow 35 retails for $209.99 on the official website or Amazon.
