Description

The NOCO GEN5X2 is a fully-sealed, waterproof onboard battery charger rated at 10 amps total—5 amps per bank—designed for 12-volt lead-acid and lithium-ion batteries, including flooded, AGM, gel, and LiFePO₄ chemistries. It’s 37% smaller and delivers 43% more power than the previous-generation GENM2, making it our most compact and advanced charger yet. Each bank operates independently, allowing you to precisely charge and maintain two batteries simultaneously, even if they differ in type or condition. Selectable charging modes—12V, AGM, Lithium, and Repair Mode—offer tailored charging for battery health and longevity, while an integrated thermal sensor automatically adjusts charging in hot and cold climates to prevent overcharging or undercharging. For severely discharged batteries, Force Mode lets you manually begin charging from zero volts, a critical advantage for recovering deeply neglected batteries that other chargers can’t detect. Engineered for the harshest marine environments, the GEN5X2 features an IP68 rating and has endured brutal life cycle testing, including thousands of hours underwater. Installation is fast and secure in any orientation—even upside down—thanks to a redesigned mounting system with an integrated anti-vibration backing that isolates shock and noise. The GEN5X2 comes with 72-inch DC cables with 3/8-inch eyelets, a 72-inch Type-B AC cable, two mounting screws, and a user guide. It’s backed by a 3-year warranty, engineered in the USA, and certified to UL1236, ISO 8846, and 33 CFR 183.410 for safety, ignition protection, and marine compliance.

  • Worth the money
Size: 10A (5A per Bank)
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. ... show more

  • One strong BEEFY brick
Size: 10A (5A per Bank)
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. ... show more

  • Battery Jumper
Size: 10A (5A per Bank)
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

  • Great on-the-boat Charger
Size: 10A (5A per Bank)
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. ... show more

  • Excellent Charger
Size: 10A (5A per Bank)
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. ... show more

  • Charger not working for the second time.
Size: 10A (5A per Bank)
This is my second charger in less than a year. First one one side quit working after about 3months. Now on my second one and the same side has quit working again. Only flashes red back and forth. They replaced the first one no charge. I'll probably have to buy the next one again. Not satisfied at all. ... show more

  • Great charger
Size: 10A (5A per Bank)
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?
