Jump starter—What can I do?

All right, all right, all right, I know that there must be a lot of people who don't know what I am, then below is my self-introduction, so attention, please.

First of all, I usually deal with your car. Maybe you've experienced this: your car's battery dies or your car breaks down while on the road. In short, you can't start the car. At this time I can play a role, you only need to connect me to the positive and negative poles of the car battery, and then you can start the car, the whole process only takes 5 seconds.

Secondly, for those friends who like to take all electronic devices such as laptops, tablets, drones, etc., if you don't have a power bank, it is definitely a bad thing. But don't worry, you have me and I can keep your device charged at the same time. Yes, at the same time. 

Finally, maybe you like adventures in the wild and need a flashlight, which is what I can do. I'm not showing off, but the light I shine is truly incomparable to a phone. In addition, I also have emergency mode, then you can use me to call for help. 

Apart from the above, I have other additional functions. I can work at high temperatures up to 131°F and cold up to -4°F. Built-in over-temperature protection allows the unit to turn off the output actively when the battery is at a high temperature. And it's not a problem to charge your car refrigerator or car vacuum cleaner. 

So, how to use me to start your car?

1. Attach the clamps to the car battery.
2. Press the power button.
3. Start your car.
4. Remove the clamps.  

Now, imagine you're driving and meeting a girl who is exactly your type. Her car broke down and she wants to ask you for help. But there is nothing you can do, so you can only say "I'm sorry, I can't help you, bye." But if you have me, maybe your co-pilot is not empty any more, and maybe it's a candlelight dinner for two at night in three days.

So, are you sure you don't prepare a jump starter in your car?
