I couldn’t be more impressed with the YONHAN Battery Charger 0-20A! This is hands down one of the most reliable and user-friendly battery chargers I’ve owned. It works seamlessly with both 12V and 24V batteries.The fully automatic features make charging effortless – just hook it up, and it detects the battery type and condition on its own.It’s built well, easy to read with the digital display, and the trickle charge/maintenance mode gives me peace of mind when leaving a vehicle parked for long periods.Highly recommended for anyone who wants a dependable, high-performance battery charger with advanced features at a great price. ⭐️

THIS CHARGER DOES CHARGE LIFEPO4 batteries to 14.6 I used it on a two new Lifepo4 100ah battery. The battery came to me with a 13.2 volt charge. I thought the same as others that the output would not be 14.6. So I took a chance. Put a voltmeter on at the very end of the charge and sure enough 14.6. Granted the resting voltage on the battery is between 13.6 and 13.8 volts after the battery is off the charger for several hours. That is where it should be. So far so good. I will try the repair mode soon and update.Update on repair mode. I tried the repair mode on a car battery that the volt meter showed 4 volts. Brought it up to 12.8 but shortly there after it dropped down to 5 v. Tried again with a lawnmower battery that showed 11.5v and it has maintained 12.6 volts for several days. I can not ask for more. Great little charger.

With either 12V or 24V, you can configure 6, 8, or 12V batteries. I did just that on 9, 8V batteries that went dead after a couple years of sitting. They would not take a charge, and I have smart chargers. This unit has repair feature, and it totally works. This thing just saved me $1000. I also used it on an expensive Prius 12V battery and saved that one too. I plan to use it on several batteries that aren’t that old, but won’t take a charge (and last)

A light weight, smaller and hi tech battery charger. My first impression was that both the plug in power cord, and the charge cable were of too light a gauge wire, for a 12 Volt 20 Amp battery charger. After using it to top up a couple of batteries; I have not had any problems with it yet, and it runs cool. With that said, I have not operated it at near the rated 20 Amp output yet, so I don't know how it will perform at higher Amp output. The battery clamps also appear to be of a very light construction, and not nearly as robust, as the clamps on my older US made battery chargers. Anyway, so far, so good, and I basically like it.

Never used it I thought by portable it meant in case of emergencies I could jump start myself off anywhere. It does need to be plugged in to charge a battery

Works great fast charging!!! Superb!!!! Great buy would buy again thinking of getting another actually so don't have to wait jus charge both at the sametime

So far this thing works just like it should. No problem with it at all. It’s a good thing!

Works for my 12 v lithium ion battery .charged it pretty fast. I have not had to charge but one time so far. The reason for four stars.
