A timer on a charger, that's it. You can cook a battery, so do pay attention. Sometimes batteries that won't charge on modern smart chargers have problems that can start fires. This beast doesn't care, it applies a charging voltage while the timer is running. It will charge a flat battery.

It does what it is supposed to. It is easy to assembly and easy to use.As stated in other reviews, the ammeter is inop (does not work). Not a big deal to me, but it does that mean that the manufacturer is using lowest bidder suppliers for part? Time will tell.In the meantime it is working just fine in my shop.UPDATE: I am changing my rating from 4 to 5. The ammeter actually does work - once the battery starts to take a charge.

This replaced my old battery charger (over 30yrs old) and works the same. I can charge a completely dead battery without a booster pack. I prefer the manual controls. The timer is different, you can't leave this one on continuously, which I've gotten used to now. I've learned to watch the voltage on the different settings if you're going to do some scan tool work key on, engine off.

Had this for awhile now. Former GM service tech familar with the midtronics GR-8 battery/charging systems diagnostic station. The GR-8 is a 60amp charger along with a bunch of other stuff. This is 50 amps and doesnt care about safety this and that. You turn that knob and amps are going to come out of those clamps and alot of them. Dim your shop lights amount of amps. Reccomend having on a 20 amp breaker. Havent used it heavily but man is it nice being able to charge customers dead batteries in about 2 hours instead of overnight with every other charger ever. Can even use it to function test starters if you know what your doing. Just dont use any more then the 10 amp setting. On 10 amps while connected to a starter on the bench the amps guage needle buries itself beyond 60 amps. Can also use it to maintain *close-ish* to charging voltage with ignition on engine off for testing purposes.The clamps are decent quality and the function knob has a heavy snap action to it. On/off/timer knob feels quality too. It says on the back there is a max 10amp continous 12v charge but when i put it on 50amps it seems to stay on 50 amps but i havent tested on a flat battery yet.
