What to Compare Before Buying
- Power supply: This model is described as running from 110V AC or a 12V car battery. Check which option suits your planned location.
- Connector fit: The hose uses an 8 mm quick connector, so confirm it matches your existing fill connection.
- Pressure requirement: The stated maximum is 4500 PSI / 300 Bar / 30 MPa. Make sure that is the figure you need for the equipment you plan to fill.
- Fill volume: The description mentions a 500 cc tank from 0 bar to 300 bar in about 20 minutes and a maximum inflation tank limit of 30 ci / 0.5 L.
- Duty cycle: A 30-minute continuous work period followed by 10 minutes’ rest is stated, so plan fills around that limit.
What Else You May Need
Check that your PCP air rifle, paintball tank or HPA tank has a compatible male nozzle or fill setup for the stated 8 mm quick connector. If you plan to use the 12V option, a suitable car power setup is required.
Before You Decide
Confirm the A3 model, the 8 mm connector and the power option you intend to use. Check the stated pressure limit against your equipment, and make sure the tank size and duty cycle suit the filling job you have in mind. Follow the manufacturer instructions for use and setup.
