## Customer Reviews

### ⭐⭐⭐⭐⭐ Charge’s different types of battery’s
*by E***  on January 14, 2025*

Made connecting to battery easy

### ⭐⭐⭐⭐⭐ Best all battery maintainer for the price.
*by G***2 on July 8, 2024*

I needed a battery maintainer that will do all types of batteries and revive batteries. I saw a recommendation for this from a non sponsored person and got it. It works great. I do wish it had a voltage screen but it is fine.

### ⭐⭐⭐⭐⭐ Saves me $7 each use!
*by M***N on July 7, 2024*

Been taking my batteries in to get charged ($7 each time) because they get too low for the Harbor Freight charger to even recognize them. Set up a totally dead battery and within a couple days on repair it was fully charged back up!If you have cars you can't run a trickle charger to and need to frequently recharge batteries, this thing seems to be a great solution.
