- Does the pump come with a battery?
- No. The kit includes the inflator and 6-inch hose only. It runs on Ryobi's 4V USB Lithium battery, which is sold separately, so budget for one if you don't already own it.
- Can it inflate car tires?
- No. It is rated to 100 PSI but is built for bicycle tires and sports balls. Car tires need far more air volume and pressure than this small 4V pump can deliver.
- How do I know when the tire is at the right pressure?
- The digital pressure gauge reads the pressure as you inflate, so you can stop at your target PSI instead of guessing by feel.
- Is $32 a good price?
- It is the best new price among the 3 stores listing it, at $32 at eBay as of November 5, 2026. Check whether a battery is included at that price, since the pump alone is what the kit covers.
- What can I inflate with it?
- Bicycle tires up to 100 PSI and sports balls such as basketballs and soccer balls. The 6-inch hose and on-board storage suit these small, frequent jobs.
