The whole concept is flawed. You simply cannot charge a 12v battery from a 12v battery. To get current and charge to transfer you would need at least 13.8v from the charging battery and at best it will manage around 12.7v if you are lucky.

You will find out it doesn't work, the first time you actually need it. There are lots of reviews on the internet, on this and others similar.
