70Mai Jump Starter: In the box

Inside the box, you will find the following elements, such as the starting device itself, crocodile Clip with a voltage converter, a black short Type-C wire for charging the device, and a brief instruction. The last one is a durable gray cover, into which you can neatly fold the entire kit.



70Mai Jump Starter: Design

The appearance of the car buster or starter is made of black high-quality plastic with a soft-touch coating, but the upper front part has a glossy insert and it looks really nothing. It is very nice to hold it in your hands and in size and weight is almost the same as a large bank.

A battery with a capacity of 11,100 mAh was installed inside the case. This is not a standard lithium-ion battery, but a lithium polymer battery is used here. It is 4-5 times more powerful than a regular lithium-ion battery.

In terms of functionality, the buster is not very rich, but lets pay a little attention to control. 


On the upper side, the Xiaomi 70Mai Jump Starter received one mechanical power button, a USB port with 5V and 2.4A, through which you can additionally charge a smartphone or other devices. Also nearby is a Type-C port for charging the launcher itself and an LED flashlight.

On the front of the glossy panel there are four LED indicators. One division is a multiple of 25% of the charge level of a lithium polymer battery.


The lower part of the device received a sticker with technical information.


The company took care of the consumer very seriously, for example, the case elements associated with high currents are well recessed into the case and protected by a silicone plug. 


The pole contacts are well disconnected and have only one single key for connecting the voltage converter.


In addition to the buster itself, the kit includes a clip. They are made of very high-quality plastic, have a rigid spring, the contacts are made of copper and a gear profile.


Also, a thick and high-quality cable will provide a high load when starting the engine. The wire is made of copper with a cross-section of 10 AWG or 5.5 mm.

The total length with a wire and a crocodile clip are about 28 centimeters. Of course, the wire is not long, but this is done on purpose since resistance and energy loss should be minimal.

There is also a car booster or starter control unit on the base. It is made of black plastic and has one mechanical device start button. 


There are also two lights – red “reverse” and green “correct”, they serve to indicate the protection of the polarity of the connection. On the side, you can see the blue contacts that need to be connected to the battery case.


The design and appearance are made very soundly, high-quality materials will ensure a long service life of the starting device for your car. 


70Mai Jump Starter: Performance and features

11100 mAh lithium-polymer battery is installed inside the case.


The rated current power is 250A, and short-term 600A, so the booster has a wide power range.

The buster or car starting is able to start the engine of a car or SUV with an engine capacity of up to 4 liters if the standard car battery is suddenly discharged.

Xiaomi 70Mai Jump Starter is equipped with ten levels of protection against voltage surges and short circuits.

At one full charge level, the booster is capable of starting the three-liter engine about 40 times, and the device’s charging time will be approximately 5.5 hours. Yes, the charging time is long, but in this way the launch device from Xiaomi will last longer.


When connecting the booster to the car battery, you must correctly select the polarity of the terminals. For example, plus is red, and the minus is black. 

Even if you accidentally install the terminals incorrectly, nothing bad will happen. The red indicator on the control unit will light up and a signal will sound.


When you installed and connected the booster correctly to the car battery, then you need to press the power button in the voltage converter unit. After which you have 30 seconds to start the engine in the car through the start/stop button or key.

If the engine does not start, the next attempt is made only after 2-3 minutes to avoid the release of individual elements of the device.

As practice shows, even such a booster power will be enough to scroll the starter of a passenger car and off-road vehicle with 12V power.

It is also worth noting that the booster is not recommended to be connected directly to the vehicle’s on-board network without a standard battery.


70Mai Jump Starter: Conclusions 

The booster Xiaomi 70Mai Jump Starter is able to start the engine of a car a large number of times without any questions.

This device is definitely suitable for any motorist, in addition, he will not take up much space, and if necessary, save it in a difficult moment.
