Our take on the Ryobi USB Lithium 4V Cordless High Pressure Inflator Kit

The Ryobi USB Lithium 4V Cordless High Pressure Inflator is a pocket-sized battery pump for sports balls and bike tires, rated to 100 PSI with a digital gauge and a 6-inch hose. It runs on Ryobi's USB Lithium 4V battery and weighs under a pound, so it lives in a gym bag or saddlebag. The best new price is $25.97 at eBay as of November 5, 2026, with 3 stores listing it new.

Questions and answers

Is the Ryobi 4V inflator strong enough for car tires?
No. It tops out at 100 PSI and is built for sports balls and bike tires. Car tires need far more volume and pressure than a 4V pump this small can deliver.
Does it work with Presta and Schrader valves?
The listed compatibility is Presta, which covers most road and hybrid bike valves. For Schrader valves you would need an adapter, so check before buying if your bike uses them.
How do I know when the ball or tire is at the right pressure?
The digital gauge shows pressure in PSI. Set your target, watch the readout, and stop when it matches.
What battery does it use?
It runs on Ryobi's USB Lithium 4V battery and charges over USB. The kit includes the battery and charger.
Is $25.97 a good price?
That is the best new price across 3 stores as of November 5, 2026, at eBay. It is a low entry point for a branded cordless inflator, though you should factor in shipping.
Can it inflate an air mattress or pool toy?
It can, but slowly. The 4V motor moves little air, so large low-pressure items take a long time compared with a high-volume pump.
Where is the Ryobi USB Lithium 4V Cordless High Pressure Inflator Kit cheapest?
At eBay, for $25.97, 40% under what the other stores charge, as of our latest check.
Where can I buy the Ryobi USB Lithium 4V Cordless High Pressure Inflator Kit?
3 stores we checked sell it, including eBay, Ryobi Tools, Walmart.
