SILCA Rechargeable Air Pump Elettrico Ultimate This electric pump promises a pumping capacity comparable to a CO₂ cartridge without producing the waste that comes with a high-pressure cartridge. Because when the battery is empty, you can recharge it using the USB-C cable. The 600 mAh battery lasts for around 8-9 tire fillings and is fully charged after approx. 60 minutes. With a pumping capacity of approx. 6.9 bar (100 PSI), you get enough pressure in the tires. To continue your ride after a puncture with the same feeling or performance, you have a digital display. With a resolution in 1 PSI increments, your usual air pressure can be set precisely. Convenient inflation is also possible with the supplied air hose. Note: Silcas rechargeable air pumps are not waterproof. Please always store the device in the zip bag provided during Transportation.
