I have tried it and it works perfectly.
Now, after 2 weeks of trying it out, I have managed to start gasoline cars, motorcycles, and diesel cars without any problems. The only negative point is that the charger provided charges very, very slowly. I got a 30W USB-C charger which works much better.
This is a lovely compact device with extra features. It also can be used to charge usb devices and has a torch function. Easy to carry and easy to use; comes with good instructions boxed. No case , but available on this site.
Everything as described, managed to do the first test on an old Mercedes diesel and the car started without any problems on the first try. The device was charged to 100% after connecting to the Mercedes, it showed 36%, the car started, and when I disconnected the device from the car, it showed 66%. I am satisfied and recommend it.
