Inflation Reference Table
| Inflatable Object | Inflation Pressure | Number of Inflations (Full Charge) | Inflation Speed |
|---|---|---|---|
| Road Bike Tire (700C25) | 0-80PSI | ≈4 pieces | ≈50~60s/piece |
| 0-120PSI | ≈2 pieces | ≈95~105s/piece | |
| Mountain Bike Tire (29×2.2) | 30-50PSI | ≈3 pieces | ≈60~70s/piece |
| 0-30PSI | ≈3 pieces | ≈70~80s/piece | |
| 0-50PSI | ≈1 piece | ≈160~170s/piece |
⚠️ Important Notes
- For resin air nozzles (TPU inner tube), use the extension hose to inflate to avoid overheating and melting.
- When targeting pressures above 100PSI, always install the extension hose to prevent air leakage from the valve.
- The extension hose can be installed directly regardless of whether a thimble is present in the valve.
- This pump is non-waterproof—protect it from rain and sweat with a waterproof bag during use.
- The air nozzle may get hot during operation; handle with care.
