A compact, lightweight, and practical mini electric pump for topping up tire pressure while cycling.
The Strummer EMP-120 is designed for cyclists who need an easy-to-carry mini electric pump without adding excessive weight. Weighing approximately 150 grams and with a footprint nearly the size of a credit card, this pump is easy to store in a jersey pocket, saddle bag, or small bag for daily cycling and emergency use.
Capable of producing pressure up to 120 PSI, the EMP-120 is suitable for road bikes, all-road bikes, and gravel bikes according to tire pressure requirements. Pressure adjustment in 0.5 PSI increments provides more precise control, while the automatic shutoff feature stops the pump automatically when the set pressure is reached.
This product supports FV and AV. In its standard configuration, the pump is ready to use with FV. For use with AV, simply flip the rubber insert inside the valve head.
Key Advantages
- Ultralight design weighing approximately 150 g
- Maximum pressure up to 120 PSI
- Pressure adjustment in 0.5 PSI increments
- Automatic shutoff when the target pressure is reached
- Compact footprint, nearly the size of a credit card
- Suitable for FV and AV
- Ideal for topping up tire pressure and emergency use
Recommended Use
The Strummer EMP-120 is recommended for topping up tire pressure and emergency use.
For regular inflation from 0 PSI, using a floor pump or a higher-capacity pump is still recommended.
Estimated Tire Pressure Top-Up Capacity
Note: The estimates above are based on internal test data using 700x25c tires, with approximately 2 full tires at 80 PSI and the third inflation reaching 60 PSI. The figures below are intended as a guide for top-up use, not regular inflation from 0 PSI. The number of pressure top-ups may vary depending on conditions, environmental factors, and usage.
| Tire Size | +5 PSI | +10 PSI | +20 PSI |
|---|---|---|---|
| 700x25c | ±44x | ±22x | ±11x |
| 700x28c | ±35x | ±17x | ±8x |
| 700x30c | ±30x | ±15x | ±7x |
| 700x32c | ±26x | ±13x | ±6x |
| 700x35c | ±22x | ±11x | ±5x |
| 700x40c | ±16x | ±8x | ±4x |
