How does a jump starter work?
The basic set also includes jump-starting cables
The 70mai Jump Starter offers a total capacity of 11 100 mAh. That’s a fairly standard capacity by today’s standards for external batteries, but this power bank will impress you with its exceptional extra feature – it jump-starts your car battery.
Special connectors for connecting original accessories in the form of jump-starting cables are located directly on the battery body.
The manufacturer states it can start a 3.0-liter car approximately 40 times. The limit was set for a 4.0-liter gasoline car and a 2.0-liter diesel car.
The battery also impresses with its extreme thermal resistance. It can operate in temperatures from -20 to 60 degrees Celsius with a start current of 250A and a maximum current up to 600A. In addition to the mentioned jump-starting cables, the basic package also includes a practical case.
But that’s not all — the device also includes a LED flashlight that works well at night and can shine continuously for up to 48 hours.

The battery is charged via the USB Type-C 5V/2.4A port, with a full charge time of 5.5 hours. Safety systems are included, such as protection against overvoltage, overheating, overcharging, and automatic shut-off.
