### ⭐⭐⭐⭐⭐ Great Charger - very good value

### ⭐⭐⭐⭐⭐ Must have for winter upkeep

### ⭐⭐⭐⭐⭐ Works great!
*by M***Y on September 20, 2023*

I recently purchased a three year old vehicle that I had shipped from New York and that had very very low mileage, so it was apparently not used a lot during the pandemic. While the 12 volt battery is holding a charge, it reads as barely over 12.1 or 12.2 volts most times and apparently this car likes it to be at least 12.4 to not give me a partially charged notice on the app. Although I've not have any start issues, I don't drive a lot myself, so I bought this to use as a trickle charge and I put it on the days that I know I'm not driving anywhere. It's been working well to keep the battery at a level where it doesn't give me that app notice. I probably need to get a fresh battery honestly, but they are high dollar and in the meantime this is helping to bring that voltage up. My first charge went all day before it switched over from an amber light charging to a green light for the 24/7 maintenance charge, but each successive time the time to switch over has been shortened. Regular use now brings the battery back up to a full charge and over to the maintenance charge in about 2 hours. Just hook it up and plug it in, so easy to use too!
