Using the Product
Turning the device on/off
Connect the car charge to the car cigarette lighter. Turn on the engine. The device will automatically turn on when it receives power from the car. The device will automatically turn off when the car charger is removed from the car cigarette lighter or when the engine is turned off.
Connecting the gas tube
Connect the device to a jeep, SUV, sedan, motorcycle or other kinds of tyres
Connect the gas tube to the tyre directly by screwing the screw-on gas connector onto the tyre's gas nozzle.
Connecting the device to an inflatable boat, inflatable toy, ball or other kinds of objects
With the standard long gas nozzle and ball needle, this product can inflate most refillable items.
Attach a suitable gas nozzle to the screw-on gas connector before connecting it to an inflatable.
The long nozzle is suitable for beach balls, floats and other inflatable toys, as well as for dust removal and cleaning.
The needle is suitable for basketballs, footballs, volleyballs and other kinds of balls.
Connecting the device to a mountain bike tyre
The device can pump a mountain bike tyre using the presta valve connector.
- Loosen the screw on the tyre's gas nozzle.

Note: After pumping the tyre, please tighten the screw on the tyre's gas nozzle again.
Detecting gas pressure
After connecting the gas tube and while the device is turned on, the pressure gauge will show the current pressure in numeric value.
Presetting the tyre pressure
Follow these steps to preset the tyre pressure:
- After the device is turned on, press the R button to switch the unit of measurement between bar, psi or kPa.
- Press the "+" or "-" button until the numbers start to flash. Press the "+" or "-" button again to adjust to the desired value. When the numbers stop flashing, presetting of the tyre pressure is completed.
Pumping
- After connecting the gas tube and while the device is turned on, press the Start button to start pumping. If the pressure of the gas valve increases rapidly within a short interval (80 psi in 3 seconds), it means that the air way is obstructed. Please immediately turn off the power, detach the rotary nozzle from the tire nozzle and reconnect the gas tube.
- When the air pressure reaches the preset tyre pressure, the pump will stop working. The pumping operation is completed.
- Remove the car charger connector and the device will automatically turn off.
Packing the device
After using the device, put the power cable and gas tube in the wire box at the back of the device.
Coil the gas tube around the winding column once, after reaching the start point, repeat the coiling one more time, then pack it in the bottom wire box along the gas tube groove. Close the wire box cover.
Checking the inflation pressure
For safety, please check the gas pressure of the object to be inflated first. This will prevent the risk of personal injuries caused by over-inflating of the object.
Tyres
The working pressure range is stated on the inside of a bicycle or motorcycle tyre. A tyre pressure guide can be found inside the door of the driver seat.
The gas pressure value is linked to the load. For more information on tyre pressure, please refer to the car's user manual.
Balls
The working pressure is stated near the nozzle hole of a football, basketball, volleyball or other balls.
Common Recommended Gas Pressure
| Inflatable Object | Classification | Recommended Pressure Rage (psi) |
| Cars | Sedans, SUVs, commercial cars, off-road vehicles | 30~50 |
| Motorcycles | Motorcycles, electric motorcycles, electric bicycles | 25~45 |
| Balls | Football, basketball, volleyball | 7~8 |
| Bike | Mountain bike, bike | 30~65 |
Notes: 1kg/cm ≈1bar≈100kPa≈14.5psi2
Precautions
To avoid damage to the device, please follow the instructions below:
- Please follow the gas pressure guide when pumping. Do not over-inflate to prevent accidents.
- Do not allow the device to operate without supervision. Cut off the power when the device is not in use.
- Do not use the product near explosive substances such as gasoline.
- This device can be operated continuously. However, at high ambient temperatures, please shorten the operation time to extend the device's service life.
- Do not point the gas nozzle at yourself or someone as the high pressure gas flow will cause injuries.
- Please uncoil the bundled power cable and straighten it out when using the device, in order to prevent potential safety hazards caused by overheating of the power cable.
