### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Optimum Performance
  

*by M***. on Reviewed in the United States on May 24, 2019*

UPDATE: 9/10/2021 - still working, use it if the bike is going to sit for a week without riding.  Use it through the winter and summer and is still going strong.Works great,Have been using one of the other popular battery trickle charger/maintainer and figured I would give this one a try.  I have used it about 6 times and have found that the battery takes less time to top off after I ride and seems to hold a charge better.One of the pluses is that the wire is very flexible and when it is cold that is a major plus for me.  Plugs into my existing plug that I was using, comes with everything you need and is 7 ½ feet long from plug to plug.Very happy with my purchase and look forward to keeping my battery running at optimum performance.

    Good value for what I needed
  

*by J***H on Reviewed in the United States on September 10, 2019*

With all the battery chargers out there, I took a chance on a "non-name brand" device.  The instructions were clear and easy to follow.  The charger works as advertised and feel this is a good value for what I needed-- so far so good!
