It performs its main function. Checked on Suzuki SX4 and Kia Picanto. In this case, even the charge does not fall. Starts at all with half a kick. The main thing is not to forget to press the button (and generally follow the instructions). As PowerBank is also not bad. The capacity is large. And it looks very cool. Nice to use. Good quality item.
I wanted to make my review more interesting by adding some photos.
