Important Safety Warnings
Please read all instructions carefully before use to prevent damage or safety risks.
- Always follow instructions carefully before each use of the emergency jump starter.
- If continuous use for jump starting is necessary, allow at least a 60-second interval between attempts.
- After 10 minutes of continuous pumping with the air compressor, stop for 10 minutes to allow the machine's temperature to decrease.
- Keep this product out of reach of children.
- Do not disassemble the machine. Non-professionals should not attempt repairs.
- Ensure the surrounding area is well-ventilated and cooling holes are not blocked during use. Avoid using in: wet places, places prone to falling, areas with vibration, corrosion, dust, chemical gases, or near flammable/explosive materials and high-temperature heat sources.
- After jump starting a car, do not charge the jump starter immediately. Allow 30 minutes for the battery to cool down.
- Do not charge the product in environments below 0°C or above 45°C.
- Do not short-circuit the positive and negative terminals of the starter output port. Avoid mixing with metal objects or sharp objects during storage.
- Before use, ensure your car is stopped and the emergency brake is engaged.
- Switch off all electrical equipment in the car before use.
- Never short-circuit the positive and negative terminals of the smart clamp, or connect them in reverse to the car battery.
- Before use, ensure the car key is in the OFF position. For smart key button (one-touch start) cars, ensure the car is completely off.
- Do not use harsh chemicals (e.g., soap, strong alkalis, acids) for cleaning.
- The power indication and patterns in this manual are for reference only; refer to the actual product.
- If not used for a long time, maintain some reserve charge and charge the product at least once every three months.
Setup
Device Overview
Button Functions
- Lighting Lamp Button (1): Long press to turn the LED light on/off. Short press to cycle through light modes (steady, SOS, strobe).
- Power/Inflate Start Button (2): Short press to turn the device on. When inflating, long press to start inflation, short press to stop.
- Mode/Unit Switching Button (3): Long press to switch air pressure units (BAR/KPA/PSI). Short press to cycle through inflation modes (car, motorcycle, bicycle, basketball, custom).
- Preset Air Pressure Increase Button (4): Short press to increase preset air pressure by 0.1BAR/10KPA/1PSI. Long press for rapid increase.
- Preset Air Pressure Decrease Button (5): Short press to decrease preset air pressure by 0.1BAR/10KPA/1PSI. Long press for rapid decrease.
Charging the Jump Starter
- Plug the charging cable into the Type-C input port (11) on the jump starter.
- Connect the other end of the charging cable to a 5V/2A or higher charger.
- The charging icon on the digital screen will flash, indicating charging is in progress.
- Charging is complete when the "IN" icon stops flashing, the power display is fully lit (showing 4 cells).
Operating Instructions
1. Jump Starting a Vehicle
- Ensure the jump starter has sufficient power (more than 3 cells displayed).
- Plug the smart clamp's EC5 connector firmly into the jump starter's start output port (9).
- Connect the red clamp to the positive (+) terminal of the car battery and the black clamp to the negative (-) terminal.
- Start your car.
- Once the car starts, immediately remove the smart clamps from the car battery.
- Unplug the smart clamp from the jump starter.
- If the car does not start on the first attempt, wait at least 1 minute before repeating steps 3-6.
Smart Clamp Mandatory Function
If the smart clamp is correctly connected but not recognized, you can use the mandatory function:
- With the smart clamp plugged into the jump starter and connected to the car battery, long press the mandatory button on the side of the smart clip.
- When the smart clip is forced open, start the car as soon as possible.
- Note: When the mandatory function is active, the smart clip's protection features are temporarily bypassed. Do not short-circuit the red and black clamps.
2. Inflating Tires and Other Items
Ensure the battery power is more than 3 cells before inflating.
- Connect the air pump hose to the inflatable pump interface on the device and tighten it to prevent air leakage.
- Short press the power button (2) to turn on the device.
- Short press the mode button (3) to select the desired inflation mode (car, motorcycle, bicycle, basketball, or custom). Long press the mode button (3) to switch air pressure units (BAR, KPA, PSI).
- Use the '+' (4) and '-' (5) buttons to adjust the preset air pressure value.
- Connect the air hose nozzle to the tire valve (or other item).
- Long press the inflate start button (2) to begin inflation. The device will automatically stop when the preset pressure is reached.
- Remove the air hose after inflation is complete.
Inflation Modes and Ranges:
- Car Mode: 1.8 BAR ~ 3.5 BAR
- Motorcycle Mode: 1.8 BAR ~ 3.0 BAR

- Basketball Mode: 4 PSI ~ 16 PSI
- Custom Mode: 3 PSI ~ 150 PSI
3. Using as a Power Bank
- Short press the power button (2) to turn on the device.
- Connect your mobile phone, PSP, MP3/MP4, tablet PC, or other digital product to the USB output port (10) using a compatible charging cable.

- Short press the power button (2) to turn on the device.
- Connect the air hose quick connector to the tire nozzle, ensuring it is pressed tightly to the bottom.
- The current tire pressure will be displayed on the screen.
6. Turning Off the Device
If the air tube is connected without pressure or there is no output from the machine, the device will automatically shut down after 20 seconds of inactivity.
Troubleshooting: Display Error Codes
The device may display error codes to indicate specific issues:
- "E1": Low Temperature Charging Protection
Unplug the charger. Continue using the machine after the temperature protection is lifted.
- "E2": High Temperature Charging Protection
Unplug the charger. Wait for the machine's temperature to normalize before continuing use.
- "E3": High Temperature Discharge Protection
Unplug any power equipment. Continue using the machine after the temperature protection is lifted.
