I am an extremely satisfied customer and would recommend this charger to anyone. I purchased this battery charger about 1 year ago, and have waited until now to post a review because I did not want to mislead anyone. I can safely say this is one of the best products available on the market.

PROS:

Accurate power display

Versatile charging settings

Compact design for easier storage and relocation solutions

Large low gauge wiring for both the charger leads and electrical outlet plug

High volume twin ventilation fans and heat dissipating fins on body

CONS:

Battery clamping jaws may be too large for some applications

Somewhat hard to understand automatic charging logic

No cranking assist

Working in a dealership, the shop provided chargers were completely unreliable and had no advanced charging functions. All it took was one failed charger mid programming, and I ended up spending 3-4 hours to fix a job that ended up paying 0.6 hours. I then decided that was enough and I needed to buy a heavy duty charger of my own. I wanted something compact that could fit in my tool box drawer for security reasons, and to make sure nobody would use it when I wasn't around. I also needed something with flash program functions to keep the voltage steady. This charger answered every need of mine and more. I am not sure who is the real manufacturer of this charger, but I have seen it rebranded under OTC and other automotive specific tool brands. It also uses a very similar charger function interface as the roll around Snapon EEBC500 unit, which is what drew me to this charger. But this charger's main advantage is the flash programming mode which allows the user to set the voltage from 13.0V and higher and the charger will automatically adjust amperage to suit, from 0 to as much as 70 amps. The large fans keep this unit cool which will aid in it's life and the low gauge wiring appears very strong and will hold up. There are sometimes the jaws will not fit on the battery itself and can only be used on the jump start terminals, so depending on different vehicles this may be an issue but it has not been for me as nearly all of the vehicles in the brand I work for have jump start terminals. It is likely possible to switch out the jaws anyhow. One odd thing is the automatic charging function which sometimes I don't understand. I am not sure if it uses the battery's internal resistance or is aiming for 12.6 volts 15.0 volts or what the case is, however I am confident it will not overcharge and "cook" a battery if left alone for hours. Overall I am very happy with this purchase, it is a tool that I feel is reliable and will last a long time as I use it almost everyday. Many technicians in the shop I work ask where I got the charger from as they can see by the build and functions this is a high quality product. Amazon has the most competitive price I found around and the purchase went smooth.

I bought this charger to replace the expensive and fragile German made chargers and so far have been pleased. If it is connected to a car and run on battery charge setting, it tends to supply overvoltage, as much as 15.6 volts and has caused overvoltage faults in control modules. If it is run on flash reprogram setting, I set the voltage to 14.8 and have had no problems. The fans are a little noisy, but in a busy shop, not too noitceable.
