  • I'm very happy with this charger
I'm very happy with this charger. Best features, can't hook it up wrong and start it! It lets you know right away if the battery is bad. The battery tender setting works great. The boost is strong and effective!

  • This is actually terrific!
I have had to use the charger so many times now! I love it! It is so easy and can be so quick when you’re in a hurry! I have kept it in the trunk of my car, along with an extension cord, which has been a life saver when my car battery has given out when I’ve been out and about! I would definitely recommend this to anyone! It’s easy to lift, easy to use and lets you know when your battery is ready to start your engine! Most of all, it works! Yeah! ... show more

  • BROKEN
We have tried to use this charger maybe at most 5 times in the last year. I think it worked once. The battery charger will not charge on any setting other than the 100 amp jump start mode. This is very sad as this unit was not very cheap. Trying to get in touch with the manufacturer and I was on hold for 10 minutes before the line just hung up. The unit still has the protective wrap on the front. Never dropped or anything, just set in a cabinet. ... show more

  • This is the boss for household battery chargers
This is a really good charger/jump starter. Heavy duty, truly farm duty. So I know this might be the last battery charger I have to buy. I can see it lasting a very long time. The cheaper ones just didn't last. They start malfunctioning after just a few uses.

  • Good bang for your buck
Charger is self explanatory with understandable directions printed right on the face of the unit and no need to read lengthily directions. Additionally it has safety features that make it difficult to screw up... It knows you connected it backwards even if you do not!

  • Works great
Had a dead car battery couple of hours after having it hooked up to the charger the battery was able to start the car
