NOCOGenius GEN5X2: 2-Bank, 10A Onboard Battery Charger - 5A Per Bank, 12V Waterproof Marine Charger with Overcharge Protection & Temperature Compensation – for Lead-Acid & Lithium Batteries

Nice battery charger that is water proof and works great. It remembers its last charging state and returns to it once you plug it back in.The mounting holes are small and you can’t o they a 10/32 nut in the provided mount. The screws it comes with are not good for salt water or fiberglass. Other than that it’s 100% I would recommend to freind.

These chargers are great, work great and well built. I own three of them now.

Product was very well packaged. Unboxing took longer than installation haha. I could tell by the weight that this product was gonna get the job done. Love the compact size and common sense for installation. I was surprised to see fuses on the negative leads. It was connected to my XS power D3400 AGM batteries. After playing around with it, the charging voltage is about 13.5 vdc. Then placed both leads on the one battery, the charging voltage jumped to 14.2 vdc. And that got me thinking about getting the 10a version. Great product. My RV electrical system says thank you.

This is a pretty good charger, a few days before taking the boat out i'll plug this in and it'll charge up the trolling battery and the starter battery and it's ready to go. I did just get a lithium battery though 100mah which at only 5amps takes about 22 hours to charge from empty. I kind of wish it had a little more oomph.You can put both charger leads on one battery and charge at 10amps but if you bolt the connections that means getting out tools moving things around, who wants to deal with all that.But so far i've charged all 3 battery types on this charger and it's worked great on all of them. Good little unit. It remembers what the battery setting was on each power up too so you don't have to mess with picking the battery each time either.

I installed the charger inside the center console of my bay boat. Easy to follow wiring diagram. I leave it plugged in all the time. It's kind of heavy so it must be quality?

First off, this is my 6th NOCO product and all have been awesome. Great chargers, boosters, etc. Quality and performance has been superb! This GEN 5X2 forced me to have to use their customer service, warranty, etc. which has also been stellar.These GEN 5X2 dual bank chargers seem to have a common issue with one of the banks failing. One bank, mine was the second bank that failed, blinks between the charge bar and the standby lights. No matter the battery, the fuse, the connection, etc. A way to test it is to use a multi-meter to test for continuity between the positive and/or negative battery lead on that bank with the a/c power cord prongs - all disconnected, unplugged, no power, etc. The good bank will have some continuity like 36-37ohms. The bad bank will have nothing, pure open circuit.If it happens within the return with Amazon then use that. Otherwise, if its under the 3yr warranty then use no.co site to contact customer service for a warranty claim. Mine was after the 30 day return window. Initially buying it we only had one battery on our boat, knowing we were getting a second house battery. A couple months later we installed a second house battery on our boat and connecting the second charger bank, it immediately started the dreaded blink between the first charge indicator and the standby light, so that bank never worked. Not sure it is an immediate fail for others but was for ours.NOCO customer service was quick and easy. I reached out late at night with their request a call option on their website. The next day got a couple calls because I didn't have my phone near me, an email with troubleshooting steps, and next steps for a warranty claim. They'll let you ship it in and wait for a return after receiving and testing the failed unit. Or, they'll let you buy a replacement from their website - which was cheaper than here on Amazon - and refund the purchase once they've receive the return faulty unit and test it to verify the unit is faulty. I chose this option for a quicker replacement.4 stars mainly for the unit failing but definitely love their products and am now a fan of their customer service. I'll follow up with review if the replacement unit fails and drop stars. If all is well, I think 4 is sufficient for an otherwise great product and company but consideration for this mishap.

The Noco battery booster is security and peace of mind in a small package. The ability to start an engine when batteries fail is a must. I’ve used the product twice and it has worked as advertised. Great product user friendly and fantastic results. Thank you

Appears very well made. Working perfectly on our pontoon
