2nd Product purchasedI bought this unit because of the extreme cold weather we have been having to help start my diesel tractor. The boost on it allows me to use the glow plugs rather than wearing down the battery. I already have one of your battery chargers and it has served me well for over 20 years.

Great for taking up extra space in the shop.Worst battery charger I've ever used. I work in an auto shop and we've had one of these for about a year, I think it successfully charged 1 battery. The computer in the charger needs to get DC voltage from the clamps before it will start charging, so it will not charge a dead battery, nor jump start a car with a dead battery. It also doesn't have an amperage gauge on it so it's impossible to tell if it's actually charging and how much power it's putting out, unless you also have an amp clamp. This unit might work well for maintenance charging but if that's all you need a much smaller and cheaper charger would serve better.

WorksThe screws that come to install the handle are not self tapping. I had to use my tap to make them fit. The holes are too small for the cheap screws that come with it. But for the price....
