Strummer EMP-120 Ultralight Electric Mini Pump
A compact, lightweight, and practical electric mini pump for tire pressure top-up needs while riding.
The Strummer EMP-120 is designed for cyclists who need a mini electric pump that is easy to carry without adding extra weight. Weighing about 150 grams and with a footprint that is almost the size of a credit card, this pump is easy to store in a jersey pocket, saddle bag, or small bag for daily riding and emergency use.
Able to generate pressure up to 120 PSI, the EMP-120 is suitable for road bikes, all-road, and gravel according to tire pressure needs. Pressure settings with increments of 0.5 PSI provide more detailed control, while the auto stop feature will automatically stop the pump when the set pressure is reached.
This product supports FV and AV. Under standard conditions, the pump is ready to use for FV. For AV use, users simply need to flip the rubber inside the valve head.

Usage Recommendations
The Strummer EMP-120 is recommended for tire pressure top-up needs and emergency use.
For routine filling from 0 PSI, using a floor pump or a larger capacity pump is still recommended.
Top-Up Tire Pressure Capacity Estimate
Note: The above estimate is calculated from internal test data on 700x25c tires, resulting in approximately 2 full tires at 80 PSI and a third fill to 60 PSI. The figures below are intended as a guide for top-up usage, not routine filling from 0 PSI. The amount of top-up 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 |
