NOCO GENIUSPRO50: 50A 6V/12V/24V Professional Smart Battery Charger – Maintainer, Desulfator & Power Supply with Overcharge Protection & Thermal Compensation – For Lead-Acid & Lithium Batteries

Very good product I'll recommend

Clever bit of kit

Bad experience, the unit is defective and missing parts and Amazon refused to return it back or refund.

Great product

This is a large unit and it's not until you open the packaging you realise how well made it is - leads in particular Very flexible covering a range of voltages- 6 to 24v A quality product albeit expensive

Perfect for flashing ECUs in a BMW. It stabilises the voltage between 13 and 14 volts.

Very good battery charger lots of features just shame couldn't be alittle cheeper

I have a number of battery banks in a camper van and an off grid hut. I have used this with mains and a generator and it works flawlessly in both environments. I have also charged a 130Ah leisure battery that had been fully discharged. I was able charge and use the repair option on the battery within four hours. I then did a ‘drop’ test to look at how much capacity I had lost and it was indicating 95% recovery which is as good as some new batteries I have tested. I am amazed that they are able to get such a high output into such a modest sized unit (although it is huge compared to regular low output chargers). All of the cabling is super high quality.

Big powerful charger with a nice power supply function. Used it several times and it works like it should. Working on a car with the supply mode on and you are sure that the battery stays 100% even with users on. Loading battery's is fast and stable. But set it on the max 10A function of the capacity is smal otherwise it could be that the battery will be Cooking by to much power. The extension cable is a real handy part. The Charger can be mounted on a wall ore a other support Service from Amazone was amazing The first one blow up just after 3 times in use. The replacement is keeping up and is still doing a good job

I am used to the noco genius 10. I have used it on ride-on mower batteries and vehicle batteries and it performs well unless you leave it plugged in and powered on for extended periods, say, around 4 weeks. The genius 10 doesn't like this and produces a fault that it doesn't recover from. The lesson has been to turn it off at the wall after each use or 24hr period. The noco genius pro50 is a much bigger enclosure with more features but not much more weight. The enclosure contains a fan that changes speed by itself, presumably to control heat. And being 50A it cycles through large car batteries a lot faster, charges them a lot faster and performs repair cycles a lot faster. If you are a mechanic, it puts 3 extra lines on your invoice in a few hours instead of over night. But what I do like about it is the 10A button. You can switch the genius pro 50 into a 10A unit for doing motorcycle, ride-on mower, or landscape equipment batteries and, like the genius 10, it also does lithium and AGM batteries too. So what is the benefit for mum and dad users of a noco unit? Your cars run better, they use less fuel, the alternator doesn't work as hard and it lasts longer, and the batteries in your cars last a lot longer. This is based on doing a 4hr cycle once per month. If you own 2 cars that are around 5 years old, a genius pro50 will pay for itself in around 3 years depending on how you drive and whether you are a city or regional driver. If you're a mechanic, how much is it worth to diagnose, de-scale, recondition, and deep charge a customer's battery in a few hours? Doing 15 batteries in a week for $110 each would pay for the genius pro 50 in a week.

The NOCO Genius PRO 50 is a serious piece of equipment. It revived a completely dead battery that had sat in my garage through three Vermont winters — something my smaller 10A charger couldn’t do. It charges fast, has excellent build quality, and works with both 12V and 24V systems. That said, it’s probably more than most casual users need. If you just top off car batteries once in a while, something like the NOCO Genius 10 or 25 might be a better fit. But if you regularly deal with large or deeply discharged batteries, this is worth every penny. Highly recommended for anyone who needs fast, reliable charging and professional-level features. Q: Will the NOCO Genius PRO 50 work on a completely dead battery that other chargers can’t detect? A: Yes, the Genius PRO 50 has a special Force Mode that allows it to manually begin charging even when a battery is deeply discharged and reads zero volts. I personally used it to recover a battery that had been sitting for over three years in freezing Vermont conditions — other chargers couldn’t even detect it, but the PRO 50 brought it back to life. It’s one of the best features if you deal with neglected or “dead” batteries.

Otrolig bra, över mina förväntan

This item saved me lots of time and money when my car lost power and the fobs were erased. Had to hook up to a constant power supply and this equipment does it all. Solid built, solid support.. Well worth the money!
