Review on Xiaomi 70mai Jump Starter Midrive PS01 by Janis Bike ᠌

A fully charged device will last for 5-6 launches. Then you need to recharge it, or immediately turn on the boost at startup. Since this is my first such device, I have nothing to compare with. But it does its job. You just need to monitor the level of its charge. Has some pros: 1. In -28 launched a 1.5-liter engine with a completely dead battery. Then I successfully did it 3 more times (2 times in boost mode) and 1 time with a 2-liter engine, before the charge dropped from 4 to 3 bars. 2. There is a fairly powerful flashlight. 3. Convenient bag included. 4. Can be used as a power bank. Got cons: 1. Once it was necessary to start the engine with a not completely dead battery (the signaling reacted, the tidy worked). I took this device, the charge showed 3 divisions (50-75% of the charge). When connected, it did not give a signal that a boost mode was required (they say the battery is not completely dead, the normal mode is enough). As a result, it was enough for about 1.5-2 seconds of starter rotation, the engine did not start, and the device no longer showed signs of life. I tried to reconnect and fiddled with the terminals, and the boost turned on - it does not react. Although the charge still showed 3 divisions. At home I charged it fully and then it already started the engine without problems. The same problem then repeated on another car - with 3 charge divisions in normal mode, it does not want to start. 2. Green and red indicators, signaling the "correct" connection of the terminals and the level of charge of the car battery, are small and dim, in daylight it is difficult to understand whether they are on or not. 3. Inconvenient boost button. 4. Of the additional connectors - only usb. Those. Not all devices can be charged from it.
