When my father-in-law – a guy who owns a tool for everything – got tired of pumping his tires by hand, he turned to this portable inflator on Amazon and hasn’t stopped talking about it since. Right now, it’s $35.99 (down from $399) for Amazon Prime members – a 91% discount and its lowest price ever recorded.Original price: $399This deal is exclusive to Prime members – and based on its price history, it doesn’t last long. Our price trackers show this tire inflator held at its $399 retail price through the first half of February 2026. It then dropped to $43 before falling again to its all-time low of $36 at the end of the month. Non-Prime shoppers still see the original price, but Prime members can lock in the 91% discount.The compact car accessory turns routine tire maintenance into a quick task that lasts just a couple of minutes, tops. The easy-to-read digital display shows the exact PSI, and once it hits the preset pressure, it automatically shuts off so you don’t have to guess or risk overfilling. It’s even small enough to stash in your glove box, keeping it handy when you need it most.Original price: $399For added convenience, this cordless, rechargeable tire inflator easily recharges via USB-C or plugs directly into your car’s 12-volt outlet — making it ideal for road trips or unexpected roadside emergencies.

It automatically shuts off once it reaches your selected pressure.We don’t know how long this price will last, but given its recent swings, it could jump back up soon.
