Review on Baseus CRJS03 black by Wiktor Wnkowicz ᠌

The charge level indicator and the device itself work unpredictably. For the experiment, I tried to start a car with a dead battery. Immediately after starting, the readings remained at 100%, and then a minute later the device began to show 75%. Subsequently, I tried to start the car again, but the charge level remained at 75%. Thus, it was not clear whether the device helped start the car this time or not. Then I charged up to 100% and left it in the trunk in the cold. So he lay somewhere for a couple of weeks, and I decided to try it again. I made sure that the charge was displayed at 100%, connected it to the battery, but did not have time to start it: after a few seconds, the red lamp on the crocodile connector lit up, which signaled a low charge. And now the charge indicator showed already 8%. Some strange system. If the battery goes to zero, it will not be possible to start the car using the device: the protection implemented on the crocodile connector will not give the go-ahead to start until it feels some voltage on the battery.
