4 in 1 Smart 12V Car Emergency Engine Starter with Tire Inflator

1. Start the car: This power supply can be used as an emergency start of the car (when the battery power is greater than 30%);
2. Air pump function: integrate an air pump, which can be used as tires, balls, swimming rings and other equipment to inflate;
3. USB output: can charge 5V digital products;
4. Lighting function: a 0.5W white LED is integrated, which can be used as outdoor lighting;
5. Tire pressure detector: integrates a digital air pressure gauge, which can be used as air pressure detection with an accuracy of ±0.1Kg/cm2;
6. Large capacity: built-in 3.7V/8800mAh high-capacity and high-safety battery pack;
7. Ultra-high efficiency: 5V/2.1A charging efficiency>70%;
8. Durable: the built-in battery can be charged and discharged for more than 500 times;
9. Safe and reliable: There is a short circuit protection design on the PCBA; the built-in lithium battery protection chip can effectively prevent the battery from overcharging, overdischarging and overcurrent.

Emergency Engine Starter Output Parameters

Output voltage: 13V ~ 16.8V (the product power must be greater than 30% when igniting the car);
Starting current: 300A, 3 seconds;
Peak current: 600A, 1.5 seconds;
Number of uses: Up to 20 starts on a single charge;
Battery clips: With overvoltage, overcurrent, low voltage, short circuit, overheating and other protection functions.
Rated for petrol engines up to 5 liters and diesel engines up to 3 liters.

Air pump output parameters:

Tires (195/60R16): 4-5 (full battery from 0 to 2.5BAR)
Airflow per minute: 34.2L/min
Motor specification: DC 15V, 120W, 18000 rpm,
Air pressure unit selection: PSI/BAR/KPA/Kgcm2
Inflatable objects: cars, motorcycles, bicycles, balls, swimming rings, etc.
Fully inflate car tires in 5 minutes (0-36PSI) or 1 minute (25-36PSI), (test data based on flat standard tires 185/65/R15). It can be used on all cars and SUVs, but not trucks and vans.

USB output parameters:

Output voltage: 5V
Output current: 2A
Overcurrent protection: 3.7A-4A (automatic disconnection)

LED lighting

Power: 0.5W;
Press and hold light button button to turn on the LED lighting;
Click the light button again to enter SOS mode, the LED will flash light.

Input and Standby Power Consumption

Input voltage: 5V;
Charging current: 1.8A-2.4A;
When charging with 5V/2A, the charging time is about 6 hours;
When the battery is charged to a voltage of 16.2-16.8V, the MCU will turn off the charging circuit to protect the battery;
The standby power consumption：≤100uA;
It will automatically shut down and enter the standby state when no operation for 5 minutes;
Or when the MCU detects that the USB port output is less than 60mA for more than 1 minute, it will automatically shut down and enter the standby state.
