1. SAFETY INSTRUCTIONS
- This product is not a toy and should not be used by children. Users should be above 16 years old.
- Keep a safe distance between children and the inflator while inflating. There is a built-in lithium battery inside the product. Don’t place the product in fire or dump the battery.
- Overheating, damage, or water may increase the risk of fire or explosion. It’s best to keep the product away from heat sources, and not leave it for prolonged periods in a hot car. If the inflator becomes very hot, there is a chance it could explode.
- Please store the product in a temperature range of -10°C~45°C. Extremely hot or cold environments may damage the battery and shorten the lifetime of the inflator.
- Long-term storage of the product may decrease the effectiveness of the battery. Charge the inflator at least once every three months to maintain its performance.
- The product has a built-in DC motor, which may generate sparks during operation. Do not use it in an environment with dust or gas that is liable to explode.
- If there is an unusual noise or the temperature becomes very high during inflation,
- Please turn off the inflator immediately.
- Before setting the inflation pressure value, make sure the pressure unit is correctly selected. Mixing up psi and bar could lead to dangerous over-inflation.
- Unit conversion: 1bar = 14.5psi, 1bar = 100kPa
- Do not leave the inflator unattended while it is in operation.
- Please use the product in a dry and clean environment. The intrusion of sand and dust may cause damage to the product. Don’t wash the product with water.
- Please use a certified 5V/3A adapter and the included charging cable to charge this product. Malfunction caused by actions not in accordance with the above requirements is not covered by the warranty.
- After running for a long time, the temperature of the junction between the air tube and the main body can become very high. To avoid burns, avoid touching it.
- Caution: To reduce the risk of electric shock, do not expose to rain. Store indoors. “Never put batteries in your mouth. If swallowed, contact your physician or local poison control center.”

4. BATTERY LEVEL INDICATOR & CHARGING
Battery Level Indicator![]()
- The battery level is shown by four bars, with each bar representing 25%.
- 1 bar = under 25%
- 2 bars between 25% and 50%
- 3 bars = between 50% and 75%
- 4 bars = between 75% and 100%
- Note: The battery indicator will flash when the battery level is below 20%.
Charging
- Fully charge the inflator before using it for the first time. To charge, connect it to a 5V/3A, 9V/3A USB charger with the charging cable.

While charging:
- 1 bar flashing = under 25%
- 1 bar solid, 2nd bar flashing = between 25% and 50%
- 2 bars solid, 3rd bar flashing = between 50% and 75%
- 3 bars solid, 4th bar flashing = 75% and 100%
- All 4 bars solid = fully charged
- The inflator will automatically switch off if left inactive for 5 minutes after being fully charged.
Note:
- The inflator cannot be used while it is charging.
- The USB charger is sold separately.
- The product will not charge when the high temperature icon is on.
Battery Information
The battery lasts about 35 minutes on a full charge, running without a load at an ambient temperature of 25°C. Using the air inflator under a heavy load or at lower ambient temperatures may reduce its battery life.
5. TURNING THE INFLATOR ON/OFF
- ON: Long-press for 1.5 seconds to turn on.
- OFF: When the inflator is turned on, long-press for 1.5 seconds to turn off.
The inflator will automatically turn off in the cases below:
- After 3 minutes of inactivity.
- When the charging cable is disconnected during charging.
- After 5 minutes of inactivity, after being is fully charged.
- When the inflator is being used as a power bank, disconnect the other device.
- Inflate for over 5 minutes when the target pressure value is below 5psi.
- Inflate for over 3 minutes when the target pressure value is above or equates to 120psi.

6. CONNECTING THE AIR TUBE AND NOZZLE
Connecting the Air Tube
Connect one end of the air tube (with screw thread) to the inflator before inflating.
Schrader Valve
Tires on cars, motorcycles, e-bikes, and most mountain bikes use a Schrader valve.
Presta Valve Adapter
Road bicycles and certain mountain bikes use a Presta valve, which requires the included Presta valve adapter to be used.
Needle Valve Adapter
To inflate balls like basketballs and footballs, the included needle valve adapter will need to be used.
7. DETECTING THE CURRENT PRESSURE
When the inflator is turned on, connect the air tube to the device to be inflated, and then the LED screen will display the current pressure value.
8. DETERMINING THE RIGHT PRESSURE VALUE
To avoid injuries from bursting items due to over-inflation, make sure you are aware of the maximum inflation pressure before you start.
Tires
The recommended air pressure of tires for cars, bicycles, and motorcycles is indicated on the tire’s sidewall. The recommended tire pressure for cars is also indicated on the inside of the driver’s side door. For details concerning load carrying capacity and recommended air pressures, refer to your vehicle’s instructions or manual.
Balls
The recommended air pressure for footballs, basketballs, volleyballs, and other balls is indicated near the ball’s air valve.
Air Pressure Reference Table

Note: Pressure range values are for reference only. Always refer to the instructions or manual of the item being inflated for actual inflation pressure specifications.
9. PRESET PRESSURE VALUE
Switch Modes: Click the Mode button to switch between the five inflation modes below. The number on the top of the screen indicates the real-time pressure of the inflated device, and the number on the bottom indicates the preset pressure.
Manual mode: When in the manual mode, no mode icon is selected on the screen. The preset pressure value is adjustable, and the value and unit will be saved.- Adjustable Range: 3-150psi/0.2-10.3bar
Car Mode: Default 36psi- Adjustable Range: 26-50psi
Motorcycle Mode: Default 35psi- Adjustable Range: 26-43psi
Bicycle Mode: Default 45psi- Adjustable Range: 30-145psi
Ball Mode: Default 8psi- Adjustable Range: 4-16psi
Note:
- When you have finished inflating an item, the manual mode will remember the target pressure value as its default pressure value.
- For the best inflating experience, we suggest you inflate items like balls via the ball mode.
Adjusting the Preset Pressure
After selecting a mode, press + or – to increase or decrease the target pressure value. Press and hold the + or – button to quickly adjust the pressure value.
10. SWITCH PRESSURE UNIT
- Long-press the Mode button to cycle through psi/bar/kPa.

11. LIGHT
- Press the light button to turn the light on/off. The light makes it easy to see in the dark when you have any tasks, such as connecting the air compressor to a valve.
- Press the light button to cycle through Spotlight, SOS, and OFF when the light is on.

Note: After 30 minutes, the light will automatically turn off.
12. INFLATING
Start Inflating
Press the Power button to start inflating. When inflating, the air compressor may be as loud as 75-80 dB. Please take appropriate precautions to protect your hearing. The air compressor and air tube can get very hot after running for a while. Avoid prolonged skin contact with the tube to prevent injuries.
Stop Inflating
Once the target pressure value has been reached, the inflator will automatically stop inflating. The inflator can also be manually stopped at any time by pressing the power button while inflating.
Caution
Items such as balloons, beach balls, and swim rings cannot be automatically inflated because they have an air pressure requirement below the air compressor’s minimum pressure range. Only inflate these items manually with caution.
13. DISCONNECTING THE AIR TUBE
The air compressor’s air hose may get very hot after inflating. To prevent injuries, exercise caution when disconnecting it from a valve. Some air may leak out of the valve when disconnecting the air compressor. To avoid pressure loss, quickly disconnect the air hose from the valve.
14. POWER BANK FUNCTION
- This inflator can be used as a 27W power bank when it is not being charged or inflating other devices.
- The battery needs to have a reasonable level of charge in order to work as a power bank.

Note:
- The inflator should be turned on when being used as a power bank.
- When being used as a power bank, the inflator will enter “Energy Saving” mode if inactive for 3 minutes, and the screen will only display the battery level icon.
- In energy-saving mode, when disconnecting the charged device from the inflator, it will automatically turn off.
