## Overview

The NOCO Genius GEN5X1 is a compact, 5-amp smart marine battery charger designed for 12V lead-acid and lithium batteries. It features advanced thermal sensing for climate-adaptive charging, a Force Mode to revive dead batteries, and a rugged IP68 waterproof build with anti-vibration mounting. Perfect for boaters and RV enthusiasts seeking reliable, efficient battery maintenance in any environment.

## Description

The NOCO GEN5X1 is a fully-sealed, waterproof onboard battery charger rated at 5 amps, 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 GENM1, making it our most compact and advanced charger yet. With a single dedicated charging bank, the GEN5X1 offers precise charging and maintenance for one battery with selectable modes—12V, AGM, Lithium, and Repair Mode—tailored to maximize battery health, performance, and longevity. An integrated thermal sensor automatically adjusts the charge based on ambient temperature to prevent overcharging in heat or undercharging in cold conditions. For severely discharged batteries, Force Mode allows manual charging down to zero volts—ideal for reviving deeply neglected batteries that most chargers cannot detect. Built for the harshest marine environments, the GEN5X1 carries an IP68 rating and has passed extensive life cycle testing, including thousands of hours underwater. Its streamlined mounting system enables fast, secure installation in any orientation—even upside down—with an integrated anti-vibration backing to minimize shock and noise. The GEN5X1 includes 72-inch DC cables with 3/8-inch eyelets, a 72-inch Type-B AC cable, two mounting screws, and a user guide. Backed by a 3-year warranty, engineered in the USA, and certified to UL1236, ISO 8846, and 33 CFR 183.410, the GEN5X1 delivers unmatched reliability, safety, and performance.

Review: I puchased this to keep the expensive type 31 batterys from sulfating on my John Deere backhoe. So far it has performed admirally. I like the fact that it has the capability to charge a totally dead battery if needed, which most other charger / maintainers won't do. I selected Noco over the brand I used to buy after seeing a comparative product review on the "Project Farm" YouTube channel.
Review: I have this installed in my slide in truck camper. It is maintaining and charging its battery when connected to shore power. SO far I have to say, I like this unit. I had an older NOCO that was great, and still is... but it is rated much lower (2.5 AMP as I recall) and did not do Lithium. I decided to up my game and use this in its place and keep the older unit as a spare. The Gen5X1 is a great unit. Its small size and higher AMP rating along with its smart settings and maintainer capabilities make it a real winner in my books. It works great, it easy to use and is very solid. All NOCO devices have excellent connectors and cables as well as a decent quality feel and function. So far after about 1 year-ish I am impressed. RV, Camper, Marine, you name it... this is a handy little unit with some power and versatility.

**Q: Can this be powered with a Modified Sine Wave inverter ?**
A: Trust the manufacturer on this question.  I am using one of these right now with an old Trace SW2512 inverter.  Works like a champ!

**Q: If power goes out while charging, will it automatically start charging when power is restored**
A: It should automatically start charging. It remembers the last setting you had it on the last time it was charging.

**Q: What's the difference between the noco genius gen5x1 (this product) and the noco genius5 charger? how should i choose between them?**
A: The GEN5X1 is an onboard battery charger/maintainer model for 12V batteries that connects to the battery via eyelets. The GENIUS5 is a multi-purpose battery charger/maintainer model for 12V and 6V batteries that comes with a clamp and integrated eyelet combo cable.

**Q: Do i have to turn this charger on everytime its plugged in or will it charge when it's plugged in?**
A: When plugged-in, the charger is in Standby Mode. Use the Mode Button to select the appropriate mode to begin charging. After each consecutive use, the charger remembers the last selected charge mode.
