The ETENWOLF Vortex S7 is a cordless heavy-duty tire inflator built around dual 260W motors and a 38,400 mAh battery. ETENWOLF claims it fills a 30-inch SUV tire in about 30 seconds and can top up roughly 33 F-150 tires from 30 to 35 PSI on one charge. That puts it well above typical handheld inflators, which are slower and run off car power or small internal batteries. It suits RV, truck and off-road owners who want cordless inflation without hunting for a 12V outlet.

It uses 260W dual motors and can inflate a 30" SUV tire in 30 seconds. It also works with bikes and other recreational inflatables, and it comes with adapters for different valve types.
A 38,400 mAh battery powers it. One charge can inflate up to 33 F150 tires (245 70/R17 31") from 30 to 35 PSI. The battery charges over USB-C fast charging, and the USB-C port also lets the unit work as a power bank for other devices.
A digital display shows the current pressure and the target pressure, with an accuracy of ±1 PSI. The inflator shuts off automatically when it reaches the pressure you set. Built-in cooling helps prevent overheating during extended use, and a 1000-lumen LED light helps in low light. A sturdy handle makes it easy to carry, and onboard compartments store the accessories.
