VEVOR PCP Air Compressor: features, specs and who it suits

The VEVOR PCP Air Compressor is a portable electric pump that fills high-pressure air cylinders, such as the reservoirs on PCP (pre-charged pneumatic) air rifles and paintball tanks. It replaces the hand pump or a trip to a fill station, and it can run from a household outlet or a car battery. Here is what its specs mean and what to confirm before relying on it.

What a PCP compressor does

A PCP airgun stores compressed air in a cylinder and releases a small amount with each shot. That cylinder has to be refilled to a high pressure, often well beyond what an ordinary garage compressor can reach. VEVOR rates this unit at a maximum of 4500PSI, which is 30MPa or about 300 bar. Always check the pressure marked on your own cylinder and never fill beyond it.

Speed and automatic stop

VEVOR says the 300W motor can fill a 0.5L cylinder from empty to 300 bar in about 18 minutes. Fill time depends on cylinder volume, starting pressure and temperature, so larger tanks will take longer. The compressor stops automatically at a preset pressure, which means you don't need to stand over the gauge for the whole fill, although it's sensible to stay nearby.

Dual display for pressure and temperature

Compressing air generates heat, so the unit shows both pressure and temperature in real time. VEVOR gives the maximum temperature as 80°C (176°F). Watching the temperature helps you judge when to give the machine a rest, as the manual describes.

Power from a socket or a car battery

A built-in converter lets the compressor run from a 120V AC outlet at home or from a 12V car battery with the supplied battery clamp. That makes it useful at a shooting range or campsite, as long as you follow the manual on connecting to a vehicle battery.

Cooling and air quality

Rather than relying on an external water pump, the compressor has a built-in fan cooling system. VEVOR describes it as oil and water free. The listing also notes that when filling a scuba diving tank, an external air filter must be connected. Breathing air has its own standards, so follow the manual and any local rules for diving cylinders.

What's in the box and how big it is

The package includes an 8mm quick-connect high-pressure hose, a battery clamp and a set of accessories for connections and replacements. The unit measures 11.8 x 7.9 x 10.2 inches (about 30 x 20 x 26 cm) and weighs 18.1 lb (about 8.2 kg), so it can be carried but is not especially small.

Who it suits

It suits owners of PCP air rifles and paintball players who want to refill at home or in the field, and anyone who needs a portable high-pressure source for compatible cylinders. People who only use low-pressure tyre inflators won't need one.

What to check before you buy

• Fittings: confirm that the 8mm quick-connect hose and adaptors match your cylinder or rifle's fill connector.
• Working pressure: make sure your cylinder's working pressure, and its test date if one applies, suits a 300 bar fill.
• Power source: check that you have a 120V outlet or a suitable 12V battery, and keep the vehicle's engine state in mind as the manual advises.
• Noise and heat: expect fan and motor noise, and allow cooldown time between fills.
• Safety: high-pressure air is hazardous. Read the manual, use only rated equipment and follow local regulations.

The short version

• A portable PCP compressor rated at 4500PSI / 30MPa with a 300W motor.
• Fills a 0.5L cylinder to 300 bar in about 18 minutes, according to VEVOR, then stops automatically.
• Dual display for pressure and temperature, with fan cooling.
• Runs on 120V AC or a 12V car battery.
• Needs an external air filter for scuba tanks, as the listing states.
