🔋 NOCO Genius GENPRO10X2 Marine Charger - 2-Bank, 20-Amp (10-Amp Per Bank) Smart Battery Charger, 12V Onboard Battery Maintainer, Desulfator, and Temperature Compensation Review

He had a problem and one of his chargers failed. I sent the device back, they checked it and sent me a brand new device. The company seems to solve problems quickly. Their only weakness is that they don't report on the progress of the repair. John

Easy to install and set up in the marine app (inside the boat console). Installation took about 30 minutes including removing the old charger. The charger works exactly as expected and advertised. Definitely recommend.

So far I've only charged 4 35 Ah AGM batteries with it. I bought it because I can charge two batteries at the same time. This is a robust charger that delivers up to 10 amps per battery (20 amps total) and can support traditional LED acid, AGM and even lithium batteries. I have several 100Ah batteries that need charging. I will inform you if anything changes. So far I'm impressed. This is a reliable charger.

My SeaRay 270's onboard charger died so after much searching I settled on a 10x2. This charger charges multiple chemicals at the same time. Before installing it on my boat, I decided to try the repair function on my truck, which has two batteries. I disconnected the batteries and installed the charger. After the repair mode has completed on both batteries, it now turns on much faster. I would definitely buy again.

I bought this charger to charge two 27 series AGM Duracell batteries on a sailboat. The batteries are only a week old and the charger says they are bad and shuts down. If you rely on your batteries to power your bilge pump off the boat, stay away from NOCO products. I tried to contact support with no response for 2 days. Plugged back in my old Promariner 5 amp and everything still charges fine, I was looking for a better charger and NOCO failed the test. Looks like I don't have $200 since I…

Got it on a Prime Day deal so the price is right. I already have a Noco Genius10 (single/portable charger) that works great. I have used this on my AGM batteries for charging, repairing and servicing. I also have some LiFePO4 batteries and this will probably be dedicated to them. My only gripe is that the Noco 10x2 doesn't support interchangeable battery connectors (alligator clips and different sized grommets). It doesn't have a quick shutdown for this purpose, which is present on my Genius…

My dual battery system never had a charger and sometimes my engine stalled due to low ECU voltage; Gone are those days, I have 13.4V every time I go out and since I have a charger I keep the screens and radios on when I anchor fish. It should have happened long ago. Self tapping screws, clear instructions, everything you need in one box. I have to say that the packaging was impressive, like opening an iPhone for the first time.

Has worked flawlessly from day one. Keeps my two deep cycle 12V AGM batteries fully charged AND quickly recharges them when they're down to 40%. I modified a 1.5kVA server rack UPS to daisy chain these marine batteries to power two of my servers during a power outage. The UPS came with a set of 4 smaller 6V batteries which were expensive to replace regularly. Although the UPS can charge 2 batteries continuously for several hours, I bought this NOCO to speed up "full recovery" loading as…

I liked the look of this unit and the obvious features. However, once installed, only one bank will work. The second bank indicates that the battery is not available even though it is connected. I went to their website and there are no manuals or support information. I'm waiting for an answer from support. Two days later no response from the company's support regarding my issue. The device still doesn't work, will be sent back and get a different brand. Wouldn't order again.

We have a class A motorhome that has been standing still for months. Home batteries have a charging system, chassis batteries do not. I installed this unit to keep the starter batteries charged and protected at all times. On my last trip I found that I couldn't start the microwave even though my home batteries showed a full charge because my home batteries had lost capacity due to a sulfation problem. I decided to test the repair function of this charger before buying replacement batteries and…
