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

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.

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.

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

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.

Quality product

This works great. Fast, easy set up. Minor complaint… the battery cable wires need to be 12-15” longer. Installing in a full size truck with dual batteries, one on each side of engine compartment, is a struggle. Longer wires would have made for easier installation. The body of the charger is well made and heavy. Set up took minutes and it works flawlessly…no more worries about battery drain when I don’t drive the truck enough.

What can i say. Wow, I never knew what i was missing. I bought this to charge both my batteries on my boat. All i can say is Wow. Its a smart charger which means it does all the thinking for you in the aspect of temperature, charging, and battery maintenance. No regrets even though the price was a little steep.

Works great. Very user friendly and easy to use.
