12V5A

I bought this charger more than 5 years ago. I used it almost every month during COVID because I was not driving much, if at all. And now, after not using it for a couple of years, I needed it again, and it worked like charm. So, nothing but praise for this little miracle! It works, it charges perfectly, it works consistently, it does not go bad if you ignore it for a few months or years, all in all, it is one of the best things I bought in a long time! AAA+++ rating. Highly recommended.

These are great chargers, I have used them for years. Will charge, maintain and desulfate. If your battery is completely dead, set it to pulse / repair, give it 30 min and change to charge.

Works well!

I had a battery go dead and looked into a jump start option to plug in as I didn't have another vehicle to hook up to for a jump. Well turns out there are few that can do a jump start that you plug in and they are a bit pricey. The way big batteries work and the type of power they use, it is more complex or not a simple thing to take the power from your wall outlets over to a device to jump start your vehicle. I didn't know that until I went looking and reading to learn about it. There are battery powered ones to jump your vehicle, but you would have to maintain them to have the power on standby to do it. I have only had a battery go bad every 3-5 years, and so wanted a device I can plug in to get a jump start if I need one. From what I read on the high priced ones that can do that, they only last a few years, so there would be a chance they would not work when I needed it. That is why I decided to go with this charger / maintainer, it will take over night or 10 - 12 hours or more to charge your vehicle battery with this to get it to turn over and start. But, this little device can sit on your shelf for years and then when you need it, you have it. If you have a emergency or need a fast jump this won't do it, but you can also use it as a maintainer to keep a battery charged, but it will have to be left plugged in and your vehicle hood left up. Such as to use at a vacation home, etc. This was the lowest priced one I could find with the smart technology to monitor the charge and keep things as safe as can be with a more hands off approach. It is not super simple such you could just do it having not read the directions, but there are no such options that easy. You will have to read up on how to charge a battery and or maintain it and become more familiar with it all to both have your battery charged proper to use it and to be safe. As it seems if you over charge your battery it can ruin it or it may explode (I am not sure). All this is why I went with this device, as I can read the directions again in the future when I need to use it and it is simple enough to then charge my battery and go about it smart and safe, so I can start my car the next morning to get to auto store to get a new one if needed.

Truck battery was dead after just doing little trips with no chance for the batter to recharge. I hooked this little charger up, let it run overnight. Truck started right up and has ever since. If the battery drains again, I’m ready to charge it with this charger. Money well spent. Already saved me a lot of time.

Only tried this past weekend on my lawnmower that has been sitting fir a year. Put charger on fir 6 hours. Battery is maintaining a full charge now.

Trabaja bien para mantener carga de baterías estacionarias

These work great as a compact charger and are extremely easy to use. I have used these on everything from large car/truck batteries, down to smaller feeder 12v batteries. As long as the battery isn’t completely bad, the repair option seems to work, it just takes time. I have bought three of these to keep in various locations and have even gifted them.

Excellent product at a good price. It fully met my expectations. It was connected to a car in the garage for 5 months, and after 5 months the car started without any battery problems.
