High Power 12V 20000mah Portable Car Battery Booster Charger Petrol Diesel Power Bank Jump Starter

This 12V 20000mAh Car Jump Starter is a life-saving device for car owners! Last month, my car broke down in a parking lot at minus 10 degrees Celsius. Thanks to the 400A peak current, I started the engine immediately, which was much easier than calling for help. It doesn't take up space when placed in the glove box, and it is especially useful at critical moments.
What surprised me the most was that it not only saved the car, but was also very practical. It has a built-in USB port for charging mobile phones. Last time I went on a self-driving tour, my mobile phone ran out of power and I used it to save it. The digital screen is very intuitive, and you can always see how much power is left, so you don't have to guess like the old power bank. When repairing the car at night, its LED light can also be used as a flashlight, which is really convenient.
Safety is also well considered, and the spark-proof design allows even a clumsy person like me to operate it with confidence. Charging is also simple, and you can just find a mobile phone charger to charge it. It can be used in everything from my sedan to my friend's diesel pickup truck, and I no longer have to worry about the car not starting in winter.
