- Reviewed in Canada on February 29, 2024Verified PurchaseYou get what you pay for, a quality product but still a little pricey.
- Reviewed in Canada on December 7, 2023Verified PurchaseCool very simple to use. Gonna try it for the winter so far so good.
- Reviewed in Canada on September 28, 2023Verified PurchaseWorks as expected very high quality
- Reviewed in Canada on July 17, 2025Verified PurchaseI bought this exact Noco 50amp charger in 2021... for $800. The fact that it's twice as much 4 years later is just disgusting. It was overpriced at $800. It didn't handle lithium batteries well, and frankly, didn't do anything that my $100-$200 charger couldn't do. This is just another one of those fluke, fad companies that are taking advantage of people in the guise of superior quality. Their products should be a 10th of the price at best.

- Reviewed in Canada on April 17, 2021This is the fastest most competent smart charger I’ve ever used. At 50-Amp it will completely charge a depleted 100 amp-hour battery in less than 2 hours. In most instances, it’ll likely top up any 6v, 12v, or 24v battery you have in less than an hour. Full featured, with additional modes like desulfination and force charging, this charger does it all and quickly. All around impressive, including the packaging, case and heavy duty nylon braided silicone cables and clamps. However, it’s not sealed or weatherproof. There are vents inside the side handles, and quiet cooling fan(s) can be heard running when it’s in use so I would be cautious using it outside or in incremental weather. For a ‘relatively’ compact 50Amp smart charger, I’m not surprised that it uses active cooling. The fact that it’s not sealed or weatherproof is a little disappointing, and I would have preferred a hard blow molded case over the included EVA case.
Overall, I’m very impressed with this Narco charger, and they have been my go to for years because of their features, reliability and compact size. I own several, and this is now my new main garage bench charger. You can find faster cheaper 100 - 150 amp chargers, but they’re not multistage, multicemistry compatible, “smart” or as feature rich. Well worth the features and time savings, but individual needs will dictate whether it's worth the price of admission.
As for features, it is capable of charging 6v, 12v, and 24v, including different multicemistry batteries including Lithium. It also has temperature compensation, reverse polarity protection, power supply mode, repair/desulfator high voltage pulse mode, trickle/maintenance, force manual mode and 10 amp charging mode for smaller batteries. The force charge mode overcomes one of the limitations of many smart chargers, which won’t actually start charging unless they’re detecting sufficient voltage, which sometimes isn’t present on badly neglected batteries. The desulfator/repair mode also helps recondition batteries that wont accept or hold a charge, and does make a difference. It will not restore batteries to 100% but it can restore them enough for them to accept a charge, so you can get some more life out of them.
It also has automatic temperature compensation charging, which allows the charger to automatically adjust the charge voltage for optimum charge efficiency depending on the ambient temperature. This is an often overlooked ‘smart’ feature but critical for optimal battery charging. It allows it to maintain a more accurate end voltage threshold balance between a full charge vs over-saturation. It does this by automatically lowering the voltage threshold when charging in warmer temperatures, and increasing it slightly in cooler temperatures. This minimizes sulfation on the negative plates, and grid corrosion on the positive plates which can damage the battery over time and lead to off gassing and water-loss.
Despite its extensive features, it’s easy to operate. One button is used to cycle through the modes/battery types. Hold for 3 seconds for repair mode. Hold for 7 seconds to force charging - once all the modes start flashing, use the mode button to cycle to the correct battery type and it’ll start force charging. The display provides clear information regarding the charge status and is easy to understand and intuitive.
Final thought: Yes, you can find a faster charger, but you’d be hard pressed to find a better more competent fast smart charger. However, it’s not weather sealed so outdoor use/installation may be limited.

5.0 out of 5 stars Loads of options and lots of power but its not cheap
Verified PurchaseBig 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 鶹e 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

- Putty 802Reviewed in the United States on July 16, 2025
5.0 out of 5 stars A True Battery Saver — Worth Every Penny for Serious Use
Verified PurchaseThe 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.
