Excellent power and speed

The features allowing a selection of charge options for various types of batteries is straight forward and easy to use. An option that few of the smart chargers have is adjustable current. The user can lower or raised the charge current in a particular setting to "tweak" the charge rate if it is somewhat too high or low. I don't know about the max 30 amp use because it is hard on the charger and battery. Very few chargers priced like this one have the 30 amp max output current . I tested a battery which was was about 40 percent discharged according to a SNAP ON battery condition tester. The Battery reached full charge in about two hours using the charger "smart" control. Battery and charger remained cool. The charger is an excellent value for the price. Be Sure to READ carefully the directions and the charger will deliver excellent charge, repair, trickle, etc.

I ordered two, one of them stopped working after a couple days, it still showed it was hooked up and fully charged even though it wasn't even connected to the battery.. cheap junk, not worth the money.
