Description

The NOCO GENPRO10X1 is a fully-sealed, waterproof onboard battery charger rated at 10 amps for a single 12-volt battery—ideal for charging and maintaining lead-acid and lithium-ion batteries, including flooded, AGM, gel, and LiFePO₄ types. Re-engineered from the ground up, it’s 27% smaller and delivers 19% more power than the previous-generation GEN1, making it the most compact and powerful 1-bank charger in its class. With selectable charging modes—12V, AGM, Lithium, and Repair Mode—you can optimize performance for nearly any battery chemistry or condition. An integrated thermal sensor automatically adjusts the charge to compensate for temperature, ensuring precise charging in both hot and cold environments. For deeply discharged batteries, Force Mode enables manual charging down to zero volts, making it possible to recover batteries that other chargers can’t detect. The GENPRO10X1 is built for tough marine and outdoor conditions with an IP68 waterproof rating and has been rigorously tested to withstand thousands of hours of use underwater. Its redesigned mounting system allows for easy, secure installation in any orientation—including upside down—and features an anti- vibration backing to isolate shock and minimize noise. The GENPRO10X1 includes 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 ignition protection and marine safety compliance.

  • An excellent charger for a multitude of battery chemistries
Size: 10A (10A per Bank)
Fantastic battery charger for a variety of uses. Have an old fashioned charger that I used for years on our vehicles on occasions when we needed. My old charger was the analog transformer style and it was quite noisy when in use. While these old chargers work fine for the occasions when you need them, they only work on the Lead-Acid style of battery found for starting engines in vehicles. Nothing wrong with that, but they cannot handle many of the newer type of battery chemistries that you can encounter. I had built my own portable power bank using a LiPo battery and needed a way to be able to charge it up. I bought this specifically for that task and it worked excellently. It charges fast and it is completely silent while in use. The smart charging circuitry is perfect for being able to adjust the charger to allow it to maximize performance and handling of the specific type of battery you are using it with. Thus it is perfect for handling both the newer LiPo batteries like I used in my power bank project, as well as replacing the older and bulkier analog chargers. ... show more

  • Best one yet!!
Size: 10A (10A per Bank)
This is my third Noco charger as my battery needs have changed over the years. Charged my lithium 200ah battery fully in about 12 hours which is perfect for marine use. Plug it in and let it do what it does! Thanks for an exceptionally well built product!

  • A simple design and well made charger that does the job without worry.
Size: 10A (10A per Bank)
What convinced me to buy this was the fact I was disappointed with the Victron Energy Blue Smart Battery Charger with blue tooth. It depended on a Bluetooth app to see the status and the app was lame. The Victron wasn't smart enough to know the battery type, you need to go into the app to select it. Anyway I'm pointing out those negatives to point out the NOCO strengths. I liked the number of reviews for the NOCO and the simplicity of the design. This unit remembers your battery once it's plugged in and just does its thing. I like the fact the NOCO has physical selection buttons on the unit. I like that it has simple to read status lights. Very easy to mount. Good purchase. Critical grading: Value for the money- fair enough Charger Quality- well made/designed well ease of use- excellent battery charge speed- average for my lithium ... show more
