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.

Excellent all-around product.
Size: 10A (5A per Bank)
This charger works great, doesn't overcharge your batteries, can be left connected to the batteries while the boat is operating, shows the charge status of each, and was very easy to install. What's not to like?

Excellent Charger – Easy Install & Great Battery Maintenance
Size: 10A (5A per Bank)
I installed the NOCO GEN5X2 onboard charger in the engine compartment of my boat, and it has been a fantastic upgrade. Installation was very straightforward. The unit is compact and rugged, and it mounted cleanly in the engine bay without getting in the way of anything. Wiring was simple and well-labeled, so the whole process went smoothly even working around other components. One of the standout features is the LED indicators. I really like being able to quickly check the status of each battery individually at a glance. Whether it’s charging, fully charged, or in maintenance mode, the lights make it easy to know exactly what’s going on without any guesswork. Another huge benefit is how well it maintains the batteries during long periods when the boat isn’t in use. During the off-season, it keeps everything topped off and conditioned, which helps extend the overall life of the batteries. That peace of mind alone makes it worth it. Overall, this charger is reliable, easy to install, and does exactly what it’s supposed to do. If you’re looking for a solid onboard charger that performs well and gives you clear status feedback, this is a great choice.

Best charger for the money

Fantastic charger, use this for my boat. Can charge lithium,AGM, or lead acid. Building well! Has mounting holes on either side for easy install. The cables are 3 foot or so. And the charger remember the battery setting for the type of battery your charging.

Excellent customer service!!
Size: 10A (5A per Bank)
I purchased this in January of 2025. The first unit lasted a year without any issues, but one of the banks failed. I reached out to Noco customer service by email and was very pleased with their quick and professional response. They arranged for me to ship it back for repairs. Within about a week I received a brand new one in the mail. The new one did have a defect out of the box, which they also quickly remedied by shipping me another new unit. That unit seems be operating as expected. Just wanted to update this purchase with this review since they had such great customer service. That is priceless these days. What a great warranty too. Well worth the money. Will be a Noco customer for life.

Potential Issue w/ 1 Bank Failing For Some but Great Warranty
Size: 10A (5A per Bank)
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.

Está todavía bajo garantía ? Porque no me funciona uno de los dos lados del cargador Outstanding customer service and a company that stands behind its products. I had an issue with my original charger, and NOCO handled the warranty process quickly and professionally. The replacement arrived much faster than I expected, and the entire experience was smooth and hassle-free. It’s refreshing to see a company that truly stands behind its products and takes care of its customers. I highly recommend NOCO, not only because of the quality of their products, but also because of the excellent customer support. They have definitely earned my trust and future business.
