It’s no secret that I’m a die-hard fan of Mi devices and gadgets. Mi 70mai Jump Starter is the perfect power bank emergency battery when disaster always seems to strike at the worst possible time. You are on the way to do your errands and your car is dead. What’s worse is you need another car or wait for your friend to come to jumpstart your car. That's when you needed Mi 70mai Jump Starter most to get going without having to spend half a day in the middle of nowhere.

You might be wondering who is 70mai, it's founded in 2016. 70mai is a Mi Ecosystem company which focuses on smart car electronics. Have sold more than 10 million units of 70mai dash cam in 92 countries around the world. It aims to level up on vehicle intelligent products, providing safe, comfortable and networked driving experience.

70Mai Jump Starter: Specifications
  • Dimensions: 163×87×27mm
  • Capacity: 11100mAh (41.07Wh)
  • Output: 5V / 2.4A, 12V jump starter port
  • Input: 5V / 2A
  • Charging time: ≤5.5hours
  • Jump start current: 250A
  • Peak current: 600A
  • Operating temperature: -20℃~55℃
  • Charging temperature: 0~55℃
  • Weight: 420g

Let's get on with the Mi 70mai Jump Starter. The basic equipment also includes a crocodile Clip with a voltage converter, a black short Type-C wire for charging the device, and a User Guide for a quick. In addition to that a handy velcro bag for storing the jumper and all the accessories.  

Using the 70mai Jump Starter
Charging the device
Connect the USB end of the charging cable to a charger or other USB power output. Connect the Type-C port at the other end of the cable to the device's 5V/2A input. 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.

Using the device as a 12V jump starter
1. Connect the jump starter to the device. Ensure that the indicator on the battery clips are off.
2. Connect the battery clips correctly to the positive
and negative ends of the car battery. The red clip
should be connected to the positive (+) end, while
the black clip should be connected to the negative (-) end.

Knowing the correct connection
  • When the green light is turned on, the connection is correct and the battery can be jump started.
  • When the red light is turned on and a buzzer sound can be heard, the clips are connected to the wrong ends. Connect the clips correctly and make sure the green light is turned on before jump starting the battery.

  • When the green light is flickering and a buzzer sound can be heard, the voltage is too low. Press the boost button and wait till the green light stops flickering. Jump start the battery within 30 seconds.

  • When both the green and red lights are not turned on and no buzzer sound can be heard, the battery may be completed damaged. Ensure that the clips are connected to the correct ends. Press the boost button and wait till the green light is turned on. Jump start the battery within 30 seconds
  • If no indicator light is on after the battery is connected, the battery may be seriously damaged. After the positive and negative connections are normal, press the BOOST button and the green light is always on. And start the vehicle as soon as possible, unplug the battery clip as soon as possible within 30 seconds after the vehicle starts.

3. After the car is jump started, remove the battery clips.

The 70mai Jump Starter offers a total capacity of 11,100 mAh. This is a relatively standard capacity for today’s external batteries, but this power bank impresses with its extra function that will kick the car battery. 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.

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.

In addition, 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 with a total length of 28 cm inclusive of the crocodile clip.
The rated current power is 250A, and a short-term of 600A to boost a wide power range and able to start the engine of a car or SUV with an engine capacity of up to 4 liters. 70Mai Jump Starter is also equipped with ten levels of protection against voltage surges and short circuits.

My Thoughts
Rated at a real 11,100mAh, that's is safe, smartly designed, easy to operate, can be used for varieties of vehicles and supports electronic charging. On top of that it can be a substitute as a powerbank for your devices that ran out of juice. From my experience as a traveler the Mi 70mai Jump Starter is the most essential tool for your next trip.

Similarly to any powerbank, it does discharge slowly, which needs to be check from time to time.
