This compact 4500 PSI PCP air compressor is engineered specifically for airgun enthusiasts, paintball players, and outdoor hobbyists who demand reliable, high-pressure inflation in a portable package. Delivering 350 watts of oil-free pumping power, this    air pump features an automatic shut-off function that stops operation once your preset pressure is reached—up to 4500 PSI—eliminating the risk of overfilling and allowing for worry-free, unattended use. The dual power capability enables operation    from either a 12V DC source (vehicle battery with alligator clips) or standard household outlets, with a built-in selector switch for seamless transition between power sources, making it equally suitable for home workshops, garage use, dive locations,    or remote field trips. The real-time LED pressure display provides precise monitoring throughout the fill process, giving you complete control over inflation progress. Optimized for small tank capacity under 1 liter (1000cc), this compressor fills    a 0.5L tank from 0 to 3000 PSI in approximately 15 minutes—perfect for quick refills before practice sessions or hunting trips. The durable steel frame construction with active air cooling system (built-in fan activates automatically to prevent overheating)    ensures long-lasting performance with minimal maintenance, while the universal 8mm quick-connect fittings offer broad compatibility with most PCP airguns, air rifles, paintball markers, and small HPA tanks.Product Parameters:    Product Type: PCP air compressor / high pressure air pump    Maximum Pressure: 4500 PSI / 30 MPa    Pumping Power: 350 watts (oil-free pump)    Power Options: 12V DC (vehicle battery with alligator clips) or household outlet (built-in selector switch)    Auto Shut-Off: Yes (stops at preset pressure, up to 4500 PSI)    Pressure Display: Real-time LED pressure readout    Cooling System: Active air cooling with built-in automatic fan    Construction: Durable steel frame for heavy-duty use    Connections: Universal 8mm quick-connect fittings    Fill Speed: 0.5L tank from 0 to 3000 PSI in ~15 minutes    Recommended Tank Capacity: Under 1L (1000cc)    Maintenance: Oil-free design for low upkeep    Applications: PCP airguns, air rifles, paintball markers, small HPA tanks    Ideal For: Home, garage, dive sites, remote field locations
