### ⭐⭐⭐⭐⭐ Very nice charger
*by S***Z on 15 March 2025*

I have a car that I do not use very often and I use this charger to keep its battery charged. I am glad I got it instead of getting a new battery. In Arizona, because of heat, the car batteries stop functioning and we may have to replace the car batteries usually every two or three years. When my car did not start, instead of trying to get battery replaced, I decided to use this charger after watching YouTube videos about it. It worked perfectly and saved me some money. It has a very nice display.
