A portable tire inflator is one of the most useful items to keep around because low tire pressure can happen at home, at a campsite, on vacation, or halfway through a long drive. It can also help you top off tires before a trip, handle slow leaks, inflate bike tires, or add air to smaller gear without hunting for a gas station pump. For anyone driving more this summer, a cordless tire inflator is a simple piece of road trip insurance.With this limited-time deal at Walmart during the retailer's Summer Deals sales event, you can get the Workprox Portable Tire Inflator on sale for just $43, a whopping 64% discount on a compact cordless inflator built for cars, motorcycles, bicycles, balls, air mattresses, and other low-pressure items. It reaches up to 150 psi and can inflate a passenger car tire from 0 to 36 psi in about five minutes.

You can run it from a 12V car outlet or the included 20V battery, and when both are connected, it prioritizes car power for longer runtime. The battery can also work as a power bank, while type-C fast charging can recharge the unit from compatible power sources in as little as 1.5 hours. The digital display shows real-time and preset pressure in psi, bar, or KPA, and the inflator automatically stops when it reaches the preset pressure outside of blower mode.AdvertisementAdvertisementRelated: Amazon Has a 'Powerful' Portable Tire Inflator on Sale for Just $30It also has a two-level LED light for nighttime use and built-in accessory storage for the 12V extension cord, battery pack, hoses, and adapters.
