VEVOR SS-PAC02A 4500PSI PCP Air Compressor: features, specs and uses

The VEVOR SS-PAC02A is a portable high-pressure air compressor for filling PCP (pre-charged pneumatic) air rifles and similar tanks. It reaches 4500PSI (30 MPa) and can run from a household outlet or a car battery, which makes it usable at home or in the field.

What PCP means and why the pressure is high

A PCP air rifle stores compressed air in a built-in cylinder and releases a small amount with each shot. Those cylinders are typically filled to pressures far above those of ordinary tyre or workshop compressors, so a dedicated high-pressure pump is needed. The SS-PAC02A's maximum is 4500PSI (30 MPa, about 300 bar). Always fill to the working pressure marked on your own cylinder, which is often lower than the maximum.

Displays and auto-stop

VEVOR says a dual display shows real-time pressure and temperature. When filling is finished, the screen shows "E4", and the compressor shuts off automatically once the preset pressure is reached. The brand quotes about 25 minutes to fill a 0.5 L cylinder from 0 to 300 bar. Real times vary with the cylinder size and starting pressure.

Linkage design and cooling

VEVOR says the compressor uses a linkage structure instead of the traditional cam design, intended to give strong performance, low noise, good heat dissipation and durability. High-pressure compression generates a lot of heat, so cooling and the temperature readout both matter in practice.

Two ways to power it

A 500W built-in power converter lets the unit run from an AC120V outlet or from a 12V car battery using the supplied battery clamp. That helps if you fill tanks at a field or range with no mains supply. Follow the manual on battery connection and vehicle engine use.

Oil and water separation

The compressor is described as oil- and water-free, with a built-in oil/water separator. Moisture and oil are unwelcome in a high-pressure air system, which is why separators are standard on this class of pump.

What is in the package

VEVOR lists an 8 mm quick-connect high-pressure hose, a battery clamp and an accessory pack of connectors and replacements. The unit measures about 14.0 x 11.2 x 9.3 inches (36 x 28 x 24 cm) and weighs 17 lb (about 7.7 kg).

Activated carbon note

The listing states that the product does not include activated carbon. For filling scuba diving bottles, VEVOR says to connect an external activated carbon air filter. Breathing-air requirements are strict, so check that any equipment and cylinders are approved for that use and follow the manual and local rules.

Who it suits

It suits PCP air rifle owners and paintball players who want to fill their own cylinders at home or on the road.

What to check before you buy

• Fittings: confirm your rifle or tank connector matches the 8 mm quick-connect setup.
• Working pressure: know your cylinder's rated pressure and test date.
• Power: check the outlet, or your car battery and clamp setup.
• Noise and heat: allow for rest periods and a well-ventilated space.
• Filtration: for diving bottles, an external carbon filter is required by the brand.
• Upkeep: check seals, hoses and the separator as the manual directs.
• Local rules: check rules on air rifles and pressurised cylinders.
