NOCO GENIUSPRO50, 50A Smart Car Battery Charger, 6V, 12V and 24V Portable Automotive Charger, Battery Maintainer, Trickle Charger and Desulfator for AGM, Lithium, Marine, Boat and Deep Cycle Batteries

Absolutely love this charger. I had the 25A charger, decided to get this one and have not been disappointed. Easy to use, not too heavy, and use it almost every day at work for programming, during diag, or just to charge up a car that’s been sitting in the stall for a bit. Very functional. A lot smaller compared to the Exteq that’s also a 50A charger. Charges pretty fast. I’ve been able to repair 2 batteries with the repair option. Definitely recommend.

This thing is a beast. I've had this thing for a year and a half already and I love it. When I park my truck for my off time and forget to turn off my power inverter, my truck will be completely dead. Hook this up to the batteries and in 10 min. The batteries are full. I've started to use the repair mode once a month because I'm trying to get the most out my batteries and its a great feature. I hate that they took the booster off the newer models but honestly, not needed. I have it mounted to my truck and it comes with more than enough cable to hard wire and mount it just about anywhere. I have a generator mounted as well so even at truck stops while on resets, I'm set. No need to turn on the truck just to charge the batteries. I just plug it in, charge for 30 min and I'm good. Owner ops, you need this.

This charger sucks. Does not rejuvenate batteries as advertised, does not charge well.

This has worked great for maintaining steady voltage during flash reprogramming and/or diagnostics in my busy automotive shop. Every function (besides 10 amp limit charge) is controlled by one button, which can be inconvenient, but I've gotten used to it. I had to keep the booklet handy for the first month or so to remember how long to press the button, and with the clamps connected or disconnected, to get into each mode. I got it on sale, I don't think I would have paid full price for it, but it is a quality product.

This thing is awesome. the battery repair feature has worked on two batteries that i thought were junk. after that they charged and held a full charge. it can also be used to power anything 12 volt or 24 volt .it's very heavy duty but compact in size and very powerfull

I bought this charger because of the 24V capability, and flexibility to charge 6V and 12V as well. The charger is large, heavy duty. I will echo another reviewer's observations that once in operation, it's not altogether obvious what the charger is doing. The instruction book tells how to access various features, and once you do that, the charger executes the command. But there's no LCD screen that indicates progress nor voltage. There is a sequence of LED's that blink, stay lit, or go out, thus indicating what's happening, or what has happened. The information is in the little manual book, and it's not completely intuitive.The sequence to access 24V functions involves pressing a button and waiting 3 seconds. I'm not real great at waiting ANY seconds... Where do I send my bill for those 3 seconds?? It's cumbersome to get to the 24V functions, and I'm pretty sure, but not certain - that I actually did get to the desulphation/rejuvination/fix your flat battery function. It seemed to work, but I was expecting that to take much longer than it appeared to take. Who knows.The charger works well. A 24V charger is somewhat a specialty item, and the fact that this is also a heavy duty charger results in the hefty price. I think if this charger had the typical LCD control display, the price would probably have been much higher, and I don't think the functionality would be any higher.I really want this to be a 5 star review, because this is a great charger, but #1, I paid full price, so my stars still belong to me (and must be earned, not sold for free stuff), and #2, the control interface and display isn't up with the times we live in. I don't need another hobby trying to figure out how to get this charger to do what I bought it for. Controls should be more simple.

Excellent product and seller!

This charger is obviously a high quality unit, and I expect it to last many years. However, it is expensive and therefore I expected a better "user experience".There are a lot of programs to charge various types of batteries, and recover sulfated batteries, which is fantastic. Accessing all these programs is not intuitive. There is a little "help diagram" on the front panel, but it's also not exactly intuitive to use.The unit really needs a small LCD display to tell you what it's doing, and also to tell you the battery voltage. The fact that a $600 charger doesn't have this is disappointing. When I first turned the charger on to charge my first battery, I was surprised to find out that after 24 hours, it was still charging and hadn't completed the charge. Concerned, I contact tech support, and they said that it is "probably" performing a recovery of a sulfated battery. Eventually after about 4 days, the charge finished. I guess it thought that it should perform a 4-day recovery process. But it doesn't tell you this-- basically this device is just a black box that does whatever it wants without informing the user of much of anything. So you're left guessing at what it's doing. For $600, I expect better.In short, the device obviously has a sophisticated internal program that gives you a lot of functionality. But with no user feedback, you just have to trust that it's doing the right thing, and you have no idea when it might finish whatever it's doing.
