Very Satisfied with the quality of the charger. Very easy to use. Works great with a variety of batteries. Nice to be able to hook up all 4 batteries at once. Would recommend the purchase!

Work as it should. I took a dead battery to a full charge. I like the features in it, like able to take care of many different type of batteries and voltages.

Great charger - only complaint is that if power is interrupted, it won't automatically go back to it's charging duties. It has to be manually restarted. That's really difficult when you are 250 miles away.

This is a do it all system. The only issue is the instructions. Truly it is easier than instructions suggest. Select battery type. Make sure the correct battery voltage is determined which it usually does. Then hit start and the auto feature does the rest. Works great.

UPDATE! Apr 12/2024The clamp tip warmed up at 19AMP and melted and I am not sure if it's mine only or all of them have had this issue.The charger never goes over 25 but it says 35 and I have tried with many different batteries but it best at 28 but doesn't stay there long. Really I would say it's a 25 at best.I bought this and I've used it for a while and there's a few issues.The unit itself overall is nice unit and seem to work well although every time you have to hit start and stop which some people prefer but the biggest issue is the grips that they're absolutely useless and very cheap as they are already bent or the metal grips are inside the plastic housing and it won't grip anything properly and the unit doesn't start till it is properly connected.It does charge faster I haven't gotten it to do 35 amp even though I've set it on that a few times but it does charge up to 30 amp no problem and the lithium setting is a little bit confusing as the lipo setting.Overall the decent product for the price but they definitely need to do something with the grips because they're very very cheaply made

i bought this cause i was sick of all the "smart chargers" that would just say bad battery when less than 9v ( automotive 12v battery) i love vevor they make some of the best re branded stuff i have ever seen. but this is the first thing that has let me down. it will not do a forced charge at 12v 20 amps.. it will do 12v and then only do about maybe 5 amps for about 2 sec then drop down to .2 - .5 amps at 12v..... the maintain feature does work thou since it will only do less than one amp over time but i have several trickle chargers that will do this for way less....

This is just what I was looking for. It will charge a completely dead battery or it will start a car while the battery is dead. The automatic battery maintain is very handy just hook it up and let it work. I also use this for my garage Diesel heater and it doesn't skip a beat.

I was looking for a high amperage automotive battery charger, so thought I’d give the Vevor a try. At $64 this is the cheapest by a good margin considering its 35 amp charging capability (not verified) and multitude of features including desulfation and force mode.I put this thing on a 105ah AGM battery that was down to 2.6V in charge mode and it wasn’t pushing any current for a while. I then put it in force mode to get the voltage up after which I switched back to charge mode and in approx 12 hours the battery was fully charged. I tested it and it tested good. The charge rate peaked at around 22 amps, but I assume that has a lot to do with the battery as well. The charger can deliver only as much current as the battery is capable of pulling.Overall, I am happy with this charger although I cannot yet speak for its durability and longevity.

I compared several battery chargers and chose this one. It was the right choice.

Just got it today. Seems well made.They say there is a Professional Mode but the manual isn't clear on how to access it. They say to press the Battery Type button while turning on the power. By that they mean while plugging it in. Not sure what the Professional Mode does. I would have liked to adjust the charge voltage manually to 14.4V instead of 14.6V but that doesn't seem possible.Still experimenting.EDIT: I checked with the company and they say that you cannot adjust the voltage in increments, like 14.2V or 14.4V ... As it turns out, the default voltage of 14.6V is fine for my battery.There is a fan and the fan speed depends on how hard the charger is working, and for how long. Even at the highest current the fan doesn't come on right away. When the fan is on and you turn off the charger the fan stays on for a while to cool down the circuit.One thing surprised me. When the charging of a LiFePo4 battery is complete the charger goes into standby mode. Fine. But when the battery voltage drops after a while the charger doesn't turn back on. You have to press the Play/Pause button to get it going. The same happens when you cut the AC power. Not a deal breaker for me, but be aware.
