I’m a self taught part time home mechanic and didn’t even know these existed until my brother had one. He told me the state police all have one in their cars. I looked at it and said there is no way this little box is going to jump start my completely dead battery. I usually can’t even get jumper cables to start a stone dead battery. So I gave it the test. My corvette was stone dead. I need an alternator. I charged it to the green lights night before….Went out and hooked it to my stone dead battery. The interior light or ignition lights wouldn’t even come on before being so dead. Hooked this up and lights came on and it started first try. I was shocked. This is a literal life saver. Not only can you just carry this in your car for easy use, but it saves you time and money having to call AAA or someone else for a jump. Also you don’t have to put your life in danger asking a stranger or some weirdo approaching you asking if you need help.
100% highly recommend.

Defective out of box
It isn’t accurate and the back light didn’t work on it being brand new so you can’t see the display at night time. If you wanna measure if someone has alcohol on breath it will do that. As far as being accurate to see if someone is under .08 bac, I would buy an alcohawk brand.
