The built-in power transformer and 12V DC capability make it especially convenient for field use, while the automatic shutoff and real-time temperature display help prevent overrun during long fills. It is best for shooters and paintballers who want a compact pump that minimizes accessories and handles fills up to 4500Psi\/30Mpa.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBuilt-in power transformer:\u003c\/strong\u003e Allows operation from 110V, 220V or a 12V car battery so you can pump at home or on the road without carrying a separate adapter.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAuto-stop at set pressure:\u003c\/strong\u003e The compressor stops automatically when the preset pressure is reached and also triggers a shutdown after 30 minutes to protect the unit.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOil- and water-free design:\u003c\/strong\u003e Eliminates the need for cooling water and oil maintenance, reducing routine upkeep and contamination risk for HPA tanks.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFan cooling and real-time display:\u003c\/strong\u003e A built-in 12500rpm cooling fan starts on power up and the temperature readout helps you monitor heat during long fills.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eQuick connector and replaceable filter:\u003c\/strong\u003e The included 8mm quick female connector and activated carbon moisture filter make hook-up fast and keep output air cleaner and drier.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFast inflating speed:\u003c\/strong\u003e Driven by a 250W brushless motor, it reaches up to 4500Psi\/30Mpa and fills a 0.5L bottle from 0 to 300bar in about 20 minutes.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eWho It's For\u003c\/h2\u003e\n\u003cp\u003eThis compressor suits PCP air rifle owners, paintball players and hobbyists with HPA tanks who value portability and the convenience of powering from AC or a vehicle battery.
