Saved my battery and my wallet
I had a completely dead battery and would have ti jump start my car to get it to start. The battery was not holding any charge it seemed as after driving for a bit and then shutting the car off it would not even start up again right after that. I bought this product and used the repair function. Now my battery is fully charged and the car starts up instantly. Great product

Very good value.
Product works great. I tried it on three different types of batteries each in a unique condition and it charged them all without over charging. Easy to operate with simple instructions.

Good charger, repair mode is great!
Great charger! Highly recommend! This is the second one that we have purchased. Small in size and convenient to use. Very impressed with repair mode- had three batteries that we thought would need to be replaced but ran repair cycle on all three to completion and have had zero issues with the batteries since.

Good battery charger
I bought this charger to replace my 6 amp charger that I tried to use to charge my off grid solar battery system when it was foggy and cloudy for over a month. This Yonhan unit was able to charge my 4 golf cart batteries when they were about 40% down. It took most of the day but did successfully charge the batteries back to full power. Only problem is that I never was able to charge at a rate over 14 amps as measured by my quality clamp amp meter even though the charger display showed 17.8 amps. I suspect that the unit could have charged my system at a rate of 15amps if needed. It may charge at a higher rate with a different system, but 15 amps is good enough for me. The plus is that when I switch to a LiFePo4 system it will also work for those batteries.

Chaaaaarge!!!!
I typically like to wait a while before reviewing items on here to ensure that I have ample time to use the item and accurately assess performance. In this case I needed to use it right out of the box, so my review is coming quicker this time!Overall first impressions:The unit is fairly compact and lightweight. The display is easy to read and the charger is intuitive. Once I connected it to my vehicle it automatically determined what type of batter was being charged, and displayed its current level of charge (11.4, which is below what it should have been).Actual use:I connected this to a diesel truck with a dead battery which was reading 11.4 volts and would not start. I left the unit connected for several hours not knowing how long it would actually take to recharge the battery. When I went out to check the status, mind you this was in 20 degree weather, I was happy to find that the battery was fully charged, as indicated on the bright display. I hopped into the truck and it fired right up! For years I had been using an older, metal charger that weighed about 20 pounds and had an antiquated display that only gave me very basic information. This Yonhan charger is FAR superior in every way to my old one, which now resides in the garbage lol.Summary:If you need a charger that can handle multiple battery types, gives you clear information about the state of your battery, and charges quickly then this is the unit to buy! The price point was right, the quality seems to be good and it functions exactly how it’s supposed to.

Charged my RV house batteries with ease!
I was skeptical at first because I was expecting it to be heavy but it charged the house 12v batteries on my RV no problem! It automatically adjusts the volts and amps and shuts down when the batteries are charged.

Saved My Golf Cart Batteries – Great Value Charger
I bought this battery charger with the hope that it could bring my golf cart batteries back to life enough for the built-in charger to kick in. To my surprise, it worked far better than expected. The charger identified three of my batteries as needing repair. I ran the repair mode for about 10–30 minutes on each battery, and like magic, they were revived. My golf cart is now charging normally through its built-in charger, saving me hundreds of dollars in replacement costs.For such a fairly inexpensive device, the results are impressive. That said, it isn’t perfect. The user interface is clunky — there’s just one button to cycle through all the modes, and the lack of customization feels limiting. My bigger complaint is the manual, which is next to useless. It barely explains how to use the repair function and mostly repeats safety warnings instead of offering real guidance.Still, despite those frustrations, the charger itself works exactly as promised, and that’s what really matters. For the price, it’s hard to beat the value.TL;DR: Brought my golf cart batteries back to life, saving me hundreds. UI and manual are poor, but performance is excellent.

I tried this charger to my semi truck 4 batteries on parallel charging and it take around 12 hours to charge all of them to full. The batteries was completely dead and didn’t charged from 8 months. I really like this charger and definitely recommend it to everyone.

Was able to charge my car with it. Case is plastic and charge cables are plastic as well not rubber and not flexible outside in the cold.
