Product detail diagram
Acts as both a car emergency jump starter to solve battery depletion issues and a high-pressure air pump to meet inflation needs in multiple scenarios.
Start cars with over 75% battery power, intelligent battery clamp with reverse connection protection, and complete startup in 30 seconds.
5 preset modes + 4 pressure units, adjustable from 0-150PSI, automatic shutdown when reaching preset value, no need for monitoring.
USB output port supports emergency charging for digital products such as mobile phones and tablets.
LED three-color modes (Constant On / Flashing / SOS) for easy operation in dark environments.
Wide temperature operation from -40°C to 60°C, stable performance in high-temperature and severe cold weather.
Large screen real-time display of pressure value and battery level for intuitive operation.
Compact size (8.6×3.5×1.8IN), comes with a storage bag for easy carrying in cars or backpacks.
Supports emergency ignition for cars to solve the problem of failure to start due to dead batteries.
Intelligent battery clamp design: Red and black clamps accurately connect to positive and negative poles (or vehicle body grounding). Flashing red and green indicators mean normal status; constant green light allows startup; constant red light prohibits startup for safer reverse connection protection.
Single startup time ≤ 5 seconds, interval between two startups ≥ 30 seconds to avoid equipment damage.
Recommended startup power: ≥75% to ensure startup success rate.
5 preset modes: Car (default 36PSI), Motorcycle, Bicycle, Basketball, Pressure Protection, one-click switching without manual parameter adjustment.
4 pressure units: PSI/BAR/KPA/kg/cm³, long press to switch to meet different usage habits.
0-150PSI wide range, pressure protection mode customizable (default 8PSI), automatic inflation when pressure drops by 5PSI.
High-efficiency inflation speed: Fast inflation for car tires, full inflation for balls/bicycle tires in minutes (specific data can be supplemented by actual measurement).
Automatic shutdown function: Real-time display of tire pressure, automatic power-off when reaching preset value to avoid over-inflation damage to tires.
USB output port (5V-2A) compatible with mobile phones, tablets and other digital products for outdoor/travel emergency charging.
Type-C input port (5V/2A, 9V/2A) supports charging via charger, power bank, vehicle-mounted interface and other methods.
Charging time only takes 5-6 hours, full charge can meet multiple emergency uses.
No need to power on, long press the LED light button for 3 seconds to start, supporting three-mode switching:
Constant On Mode: Lighting for night operation.
Flashing Mode: Warning reminder.
SOS Mode: Emergency distress signal.
High-brightness LED beads with strong penetration, practical for outdoor emergencies.
Overvoltage protection, overheating protection, short circuit protection, reverse connection protection to avoid dangers caused by misoperation.
Shell made of PC/ABS flame-retardant material, high temperature resistant and impact resistant.
Automatic shutdown for cooling after 10 minutes of inflation (5 minutes cooling time) to extend equipment life; automatic power-off in case of abnormal noise/high temperature.










Connect the inflation hose with the corresponding adapter and clamp it to the tire valve → Long press the power button to turn on, the screen automatically displays the current tire pressure → Short press the "Mode Button" to switch to the corresponding scenario (e.g., Car Mode) → Press the "+/-" buttons to adjust the target tire pressure, start inflation automatically, stop when reaching the target → Unplug the air tube after cooling and store the accessories.
Turn on and check the battery level (≥75% is optimal) → Connect the red clamp to the positive pole of the battery and the black clamp to the negative pole (or metal grounding of the vehicle body) → Insert the battery clamp into the EC5 port of the main unit, start the car when the indicator light is constant green → Unplug the port first, then remove the clamps within 30 seconds after the car starts.
Charge the main unit: Connect the Type-C cable to the input port of the main unit, and the other end to a charger/vehicle-mounted USB → Charge digital products: Connect the USB cable to the output port and the device after turning on the main unit.
In shutdown state, long press the LED light button for 3 seconds to turn on, short press to switch modes (Constant On→Flashing→SOS→Shutdown).
Ensure the main unit's battery level is ≥75% before use, interval between startups ≥30 seconds, no more than 3 consecutive startups.
Avoid storing in high-temperature, humid, or strong magnetic environments, and keep away from fire sources.
Do not aim the air tube at the mouth, ears, or eyes of humans/animals during inflation; cool for 5 minutes after 10 minutes of inflation.
Forbidden for children to use; keep a safe distance during operation to avoid squeezing/colliding with the equipment.
Do not use electrical appliances exceeding the output current to prevent triggering circuit protection.
Charge and discharge once every 3 months when not in use for a long time to extend battery life.
Keep the main unit dry and clean to avoid sand and dust entering the ports.
Built-in lithium battery is prohibited from being soaked; do not disassemble by non-professionals.
Priority use of original Type-C cable for charging to avoid poor contact.
