## Customer Reviews

### ⭐⭐⭐⭐⭐ Dependable & simple
*by G***L on May 31, 2025*

Easy to use and has kept my motorcycle battery ride ready.

### ⭐⭐⭐⭐⭐ Brilliant for My Motorcycle and Lawn Mower During New England Winters (Or Periods of Inactivity)
*by D***E on January 26, 2013*

This is an amazing product. I connected the included adapter to my Ducati Monster S4R and I can just easily connect this charger to it whenever I need to keep the battery fresh (or just leave it on if you want).I also use the included set of clamps to keep the battery healthy on my Husqvarna mower (Husqvarna YTH23V48-CA 48-Inch 724cc 23 HP Briggs & Stratton Intek V-Twin Pedal Activated Hydrostatic Transmission Riding Lawn Tractor (CARB Compliant) - awesome mower also bought on Amazon).It's better than other trickle chargers I've had because it even revives dying batteries and keeps them healthy.If you got this far in the review just click buy. You know you deserve it. :o)

### ⭐⭐⭐⭐⭐ Easily 5 stars
*by M***L on February 10, 2020*

Bought 1 and it brought back a battery from the dead, so I bought another one for my other bike. These are the best of the best, worth every penny. Works as it is supposed to. How many times can you actually say that?
