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

The Ryobi USB Lithium 4V High Pressure Inflator is a pocket-sized battery pump for bicycle tires and sports balls, rated to 100 PSI with a digital gauge. It runs on Ryobi's USB Lithium battery system, charges over USB, and stores its 6-inch hose and accessories on board. At $34.99 at eBay as of November 5, 2026, it sits at the low end of its recent range across the four stores that list it new.

  • PortabilityPraisedAt under 1 lb it is easy to toss in a bag or jersey pocket.
  • Inflation speedCriticisedThe 4V pump is fine for balls and bike tires but slow on larger volumes.

Questions and answers

Is $34.99 a good price for this inflator?
It is the lowest new price among the four stores listing it as of November 5, 2026, so it is a solid buy at that figure. Check whether the kit includes the battery and charger, since that changes the value.
Can it inflate car tires?
It is rated to 100 PSI, which covers most car tire pressures, but the small 4V pump will be slow on a large tire. It is better suited to bike tires and sports balls.
Does it work with Schrader valves?
The listing specifies Presta valves. For Schrader valves you will likely need an adapter or a different chuck.
What comes in the kit?
The kit includes the inflator, a USB Lithium battery, a 6-inch hose and on-board accessory storage. Confirm the charger is included at the store you buy from.
How do I charge it?
It charges over USB through the USB Lithium battery, so any USB power source works.
Is it worth it over a hand pump?
It is faster and easier than a hand pump for balls and bike tires and gives a digital pressure reading. A hand pump costs less and never needs charging.
Where is the Ryobi USB Lithium Cordless 4V High Pressure Inflator Kit cheapest?
At eBay, for $34.99, 19% under what the other stores charge, as of our latest check.
Where can I buy the Ryobi USB Lithium Cordless 4V High Pressure Inflator Kit?
4 stores we checked sell it, including eBay, Ryobi Tools, Walmart, Amazon.
