Love this little unit. Works as advertised and very simple to use…. My car warning lites were going off and the dealer would have to reset and couldn’t find anything wrong…. Found out you need a battery that’s charged properly. This little guy did it perfectly. No more warning light

I bought this as a gift for my friend. We live in a cold climate so sometimes you need a little extra boost in the winter. He loves it he thinks it's great and would purchase it again

Works like a charm. Used it on a 1997 Dodge Ram 1500 truck that rarely gets driven. I have a solar panel in the windshield to keep the battery charged but all of a sudden it stopped working. I tried to start the truck with my jump starter but the battery was too low. It wouldn't even start using my SUV to jump start it. I was looking to buy a new battery (This one is 41/2 yrs old) and decided to try this first. It said it would bring back a dead battery and it did. Charged it overnight and it came back to life. I now use it for our VW camper and the truck both who get little road time. Saved me a new battery and keeps both vehicles us and running.

My hubby is very happy with this little unit. It worked perfectly on our plow truck that we needed to jump start when it was -30.

The repair mode saved me. I had accidentally turned the rear interior light on when moving a bulky item into the back seat of my Sonata. Didn’t notice it, so when I went to use the car a few days later the battery was completely dead. It checked at 5 volts, so I knew there was a potential for damage.I have one of those small boosters which always work for others I help. I completely drained it in minutes just connecting it to the dead battery. I used to have the big roll out charger and booster. Now in a condo, space is a premium. Everything has to be tucked away in a spot somewhere.This charger is the real deal. It did the repair in hours and then charged the battery to top voltage. It is small and unexpectedly light compared to the heavy units that used copper wound transformers for decades. It doesn’t throw heat and has one button operation thanks to the use of a microprocessor.It is also highly versatile, being able to charge 12 and 24 volt batteries. Great for home backup systems using the latest in battery technology.

This battery charger is a lifesaver! It’s fully automatic and works great for maintaining and charging all types of batteries, including LiFePO4, AGM, and deep-cycle batteries. The battery repair function is a fantastic feature that helped restore an old battery I thought was dead. I also love the winter mode, which ensures reliable charging even in colder temperatures. The LCD display is clear and easy to read, making it simple to monitor the charging process. It’s well-built, user-friendly, and a must-have for anyone needing a reliable trickle charger. Highly recommended!
