Leave your CO2 and Floor Pumps at home with a small battery powered option that has a highly accurate gauge. Since 1917, SILCA has led the way in precision inflation, from the world's first gauge-equipped pump to the legendary SuperPista and Pista floor pumps. Now, with over a century of expertise, SILCA is revolutionizing inflation again with the ELETTRICO series -- the first truly premium rechargeable electric mini inflators. SILCA ELETTRICO MICRO & ULTIMATE provide CO2-level inflation performance in a USB-C rechargeable, air-travelsafe package. No more wasted cartridges. No more pressure inconsistency. Just on-demand, precise inflation for every ride. WHY SILCA ELETTRICO? The days of CO2 cartridges are officially over. The SILCA Elettrico MICRO packs the power of 4+ CO2 cartridges in a package about the size of an AirPods case. With auto-cutoff at 72 psi (no gauge), it's safe for use with hookless rims. A single 25-minute charge provides enough power to last for months, ensuring it always has your back. The Elettrico Micro is our on-bike inflation solution. While the Elettrico ULTIMATE is ideal for destination gravel events or even as a floor pump replacement in your garage. Dialing in your tire pressure before a race or ride has never been easier with the 3-100 psi settable, auto cut off gauge. We have even used it to set up tires tubeless (will depend on tire and rim combo). CO2 Performance Without the Waste - Eliminate disposable cartridges. Auto Shutoff for Hookless Rims - Protects modern tubeless setups. Air-Travel Safe - TSA-compliant for travel and destination rides and races. USB-C Rechargeable - Fast-charging for reliable inflation. Universal Chuck Compatibility - Works with SILCA Schradero & Hiro Chucks.
