  • Perfect! Good Quality!
Style: Charger
My husband has a low rider. He gets up early, puts the charger on the hydraulics and within a few hours, he's ready to go. I'm sure he believes this gift was better than the apple watch that I got him.

  • Schumacher quality!
Style: Charger
I have had this charger for a couple years now. I use it for my motorcycle batteries - mainly as a trickle charger over the winter. It runs six months 24/7. Two winters so far; going into the third. I also use it to charge my Corvette battery when it runs down. Great unit. Expect it to perform for many years. ... show more

  • solid state Schumacher delivers excellent control and battery management
Style: Charger
This 4-position charger is quiet and high-performance addition for our garage. I maintain 8 separate vehicle batteries with this charger across 5 different vehicles for 8 months every year in Alaska. After two years of use it's already paid for itself and is working like the day it was new.
