Meet the GEN5X2 – Similar to our GENM2, only better. It’s 37% smaller and delivers 43% more power. It’s one of the best performing onboard marine battery chargers we have ever made.
Multiple banks – A two-bank onboard battery charger rated a 10-amps – 5-amps per bank – for 12-volt batteries, including marine, boat, starter, and deep-cycle batteries.
Charging modes – Independently charge and control each battery bank with selectable charging modes – including 12V, 12V AGM, 12V Lithium, and 12V Repair Mode – for all types of lead-acid and lithium-ion batteries.
Enjoy precision charging – An integrated thermal sensor detects the ambient temperature and alters the charge to eliminate over-charging in hot climates and under-charging in cold climates.
Charge dead batteries – Charges batteries as low as 1-volt. Or use the all-new force mode that allows you to take control and manually begin charging dead batteries down to zero volts.
Redefined mounting – A simplified mounting system allows for quick and easy installations in any direction – even up-side-down – with an integrated anti-vibration backing to isolate shock, vibration, and noise.
Designed for water – A fully-sealed and waterproof onboard battery charger with an ingress protection rating of IP68, but has survived brutal life cycle testing, including thousands of hours underwater.
What’s in the box – GEN5X2 10-amp 2-bank waterproof onboard marine battery chargers (120-240VAC) with a 72-Inch DC cables with 3/8-inch eyelets and a 72-inch Type-B AC cable, (2) self-tapping mounting screws, user guide, and 3-year warranty.

Sticking with Noco!
Great product especially for the price. The ability to repair flooded cell batteries and have convenient troubleshooting features was very helpful. After my old charger on our boat failed I quickly purchased the 5X2 genius, simply plug and play, it advised that I had 1 battery not holding charge which I replaced. I really like how this is a sealed unit and doesnât have a cooling fan (eventually building up dirt around the electronics). I will be purchasing Noco products from here on out!

Potential Issue w/ 1 Bank Failing For Some but Great Warranty
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.

Every time I plug in this charger I smile inside (and possibly outside:) . At first, I had intended to use it for both my Boat and my Vanagon. Now, because of its convenience, I have decided to purchase a second unit for the van. Its ability to charge different types of batteries, display their charge status, run maintenance cycles, it’s waterproof for splashes or spills; everything I’ve been searching for in an onboard charger… Great product, I highly recommend it to those hunting for convenience and robust quality. It feels like and appears to be, build to last.

Fitted this in my boat, (as it has 2 batteries). It’s an extremely high quality product that keeps the batteries in tip top shape via the mains. I’ll be hooking it up to a solar panel next, so I’ll update here when I know the results.

My problem with it that it doesn’t come with quick connect end, only with terminals. Not sure what am I going to solve this problem now as all my cars are with quick connect.Other than that, this’s my third NOCO charger so it’s amazing.
