Power Off: Press and hold the power button for 3 seconds to turn off the
air pump.
Method of Pumping
In the power-on state, single press the power button to start inflate, and it
will automatically stop inflating when the preset air pressure value is
reached.
Battery Indicator
Different colors of the battery indicator show different battery levels:
- Green: 70%~100%
- Yellow: 30%~70%
- Red: 5%~30%
- Red flash: below 5% (in a low battery state, need to be charged before using)
Charging Method
USB-C charging input 5V/2A, please use a charging cable and connect it with
the power adapter (need to purchase by yourself) to charge the air pump.
Battery indicator when charging:
- Green light flashes: Charging
- Green light on: Fully charged
Note: The air pump cannot be used during charging.
Air Pressure Unit Switching
Short press the U icon, the air pressure display unit can be switched.
Unit conversion formula: 1 PSA = 6.89 KPA 1 BAR = 100 KPA 1 KG/cm2 = 90

LED Light
Long press the button to turn on the LED light, switching the lighting mode
and turn off the LED light.
Power on the device, long press the button to turn on the LED light. There are
three lighting modes, torch light mode, strobe light mode and SOS light mode.
- Long press the button to switch the lighting mode in sequence. At the SOS light mode, long press button to turn off the LED light.
Preset Air Pressure
- Short press the +/— button: Adjust the preset air pressure value 0.5PS/ per press.
- Long press +/- button: Quickly adjust the preset air pressure value.
Check The Air Pressure
With air pump in standby status, after the trachea is connected to the air
pressure detection object, the upper half of the air pump display screen is
the present measured air pressure value.
Pressure Reset
After power on, the trachea is not connected to the inflatable object. When
the measured pressure value is not 0.0, press the + and -button at the same
time for 2 seconds, and it will return to normal after all lights of the
display screen are on.
Note: The default air pressure value of this product has been reset into zero. Due to the difference in altitude or sensor, when the measured air pressure value is not zero, manual reset can improve the air pressure accuracy. Calibration is not recommended when the device at high temperature status after inflation.
Application Scene Switching
Short press the ****button to select 5 inflatable scene modes, they
are:
Confirm inflating pressure
To ensure safety, please check the inflation pressure required by the inflated
item according to their instruction manual before inflating, to avoid personal
injury from explosion caused by excessive inflation.
-
Car Tires
The pressure range of the car’s tires is marked on one side of the tire. The inflation pressure will be related to the load weight, for more detailed air pressure recommendations, please refer to the manual of the relevant vehicle. -
Motorcycle Tires
The pressure range of motorcycle tires is marked on the side of the tire. The inflation pressure is related to the load weight, for more detailed air pressure recommendations, please refer to the manual of the relevant vehicle. -
Bicycle Tires
The pressure range of a bicycle tires is marked on the side of the tire. The inflation pressure is related to the load weight, for more detailed air pressure recommendations, please refer to the manual of the relevant vehicle. -
Balls
The inflation pressure of football, basketball, volleyball and other kinds of balls is marked around the gas-filled pore. The inflation pressure is related to the load weight. For more detailed air pressure recommendations, please refer to the manual of the relevant ball.
Connect The Air Trachea to The Air Valve
-
American valves
Mountain bikes, electric bikes, motorcycles, and motor vehicles will be equipped with american-style valves.
Inflation: Connect the american-style air valves to the american-style quick-connect trachea to inflate. -

1. Connect the French valve adapter to the American air valve of the high pressure air trachea.
2. Unscrew the cap of the French valve
3. Connect the French valve to the adapter to inflate.Ball Valves
Ball valves are needed when inflating balls such as basketballs and soccer
balls.
Inflation: After connect the ball valve with the American air valve of
the air trachea. Insert the ball valve into the inflation hole on the ball to
inflate.
Power Bank
The battery capacity of the smart air pump is 4000mAh, and the 5V/2A USB-A
output interface can be used to charge electronic devices such as mobile
phones.
Note: Inflation and charging cannot be performed at the same time.
