Bought this to charge 12v trail cam batteries. Failed 2 mos after warranty. Would not set a amp setting. Contacted seller about possible repair, but they talked like they would honor the warranty. In the end they didn't, which I expected but then they told me this unit was not made for what I was using it for..WHAT! I told them if that is the case their add should reflect that. This unit charged them fine for awhile but then puked it up. You can come to your own conclusion but I ain't buying another one from NICE.
