POWNYM 221B Compact Wireless Tire Inflator — Mini Digital Air Pump for Cars, Bikes & Balls

Small enough for a glove box, powerful enough for any tire. The POWNYM 221B is the ultra-compact cordless tire inflator designed for drivers who want reliable air pressure at their fingertips without carrying a bulky compressor. With 150 PSI output, a built-in digital gauge, and a rechargeable battery, this mini air pump handles car tires, motorcycle tires, bicycle tires, and sports balls — all in a device that weighs under a pound.

Why the 221B Is Your Everyday Inflation Companion

Tire pressure drops naturally over time — about 1 PSI per month under normal conditions. Under-inflated tires reduce fuel efficiency by up to 3%, shorten tire life by 25%, and compromise braking distance. The 221B makes it effortless to check and top off your tires weekly, keeping you safer and saving money on gas and tire replacements. Its compact form slips into any glove box, door pocket, or backpack — you'll always have it when you need it.
