By DeeMee One reviewer said it was complicated. I agree the controls and labels are unintuitive. Not informative in a clear manner. But the operation is pretty simple. A few minutes reading the instructions make sit clear enough. A couple of uses and it all makes sense. This unit can check your alternator, tell you if a battery has an open or shorted cell. It can recondition batteries suffering from sulfanation. It will charge at 25 amps which is faster than many chargers. Plus it can put out 75 amps for a short time to give a quick boost. All in all a good charger for many purposes. I will deduct one star for the non-intuitive design which easily could have been made a non-issue. 2 of 2 people found the following review helpful. This does NOT have an Air Compressor...and very complicated By GrassRootsShop This does NOT have an Air Compressor as stated on the Amazon page. And even if it did I would still return it as it is very complicated. The user manual is a nightmare. There is no easy quick start instructions Perhaps this is appropriate for a Profession car mechanic. Nothing easy or intuitive about the unit or the manual. This is likely a quality product from B&D, but seems like a collage class is necessary to use the damn thing. I plugged it in, I got a bunch of flashing lights, beeping, and codes on the LED screen. Forget it. See all 4 customer reviews....
