I have mixed feelings

I bought this product with high expectations that I will enjoy it. I had a car battery issue yesterday and I went to get the product to start my car but to my greatest surprise, it didn't work although it was able to power up the windows but the car didn't start at all. Appreciate it if I can get a feedback on how to use this device as it is not working for me and am not happy about it.
