                One wheel was bad. The unit did not work at all. I plugged it in and it’d blink at me every few minutes. I had to box it up and take it back. So I wasted time and money for nothing.

                Ok, I guess.
                I had an old charger ,and I needed to replace it. I never noticed it had the digital controls I prefer my old charger, that had a timer and controller switch.

                Perfect for what I needed it for. We have a fleet of vehicles that need to be on the road. Incase of a dead battery now we can jump start them.

                I 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.

                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.
