  • (2) Self-Tapping Screws
  • User Guide & Warranty Information
  • A two-bank on-board battery charger rated at 20-amps for 12-volt batteries, including marine, boat, starter, and deep-cycle batteries.
  • 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.
  • 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.
  • 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.
  • Automatically detects battery sulfation and acid stratification to restore lost battery performance for stronger engine starts and extended battery life.
  • It's not just a trickle charger; it's an advanced battery maintainer. A fully automatic, worry-free battery charger for everyday use - 24/7 - with zero overcharge.
  • 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.
  • 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.

Meet the all-new GENPRO10X2. Similar to our GEN2, only better. It's 19% smaller and delivers 33% more power. It's one of the best performing onboard marine battery chargers we have ever made. A two-bank onboard battery charger rated at 20-amps (10-amps per bank) for 12-volt batteries, including marine, boat, starter, and deep-cycle batteries. 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.

Advanced Charging

Five unique modes to handle all your charging needs.

12V mode for wet, gel, enhanced flooded, maintenance-free, & calcium batteries. 12V AGM mode for AGM or maintenance-free batteries. 12V Lithium for Li-Ion and LiFePO4 batteries with a Battery Management System (BMS). Repair mode to repair old, idle, damaged, stratified, or sulfated batteries. Force mode to charge batteries below 1-volt.

100% Waterproof

Rated to IP86. Fully-sealed charging.

The GEN Series is 100% waterproof and designed to withstand hours underwater. The GENPRO10X2 is an on-board charger built for extreme conditions.

The Next Generation of Charging

NOCO's most powerful, efficient, and compact charger yet.

Compact, yet powerful battery charger. A mix of electrical engineering and industrial design pack a powerful battery charger into a tiny footprint. The GENPRO10X2 uses high-frequency switch-mode technology to efficiently convert A/C power into safe D/C power for battery charging. Its onboard microcomputer precisely controls the charging to minimize power loss to create an incredibly compact form factor.

Do More With One Charger

Multi-chemistry. Multi-battery type.

A multi-functional design that allows you to charge in more ways. Effortlessly charge 12-volt lead-acid and lithium-ion batteries of multiple chemistries (Flooded, gel, maintenance-free and AGM batteries) and types (Starter, deep-cycle, marine, and more).

Charge Dead Batteries. Down to Zero Volts.

Improved start voltage sensor. All-new Force mode.

The all-new start-voltage sensor allows the Genius GEN charger to detect and charge dead batteries as low as 1-volt. For extremely dead batteries lower than 1-volt, manually turn on force mode to detect and charge batteries all the way down to zero volts.

Thermal Compensation

More precise charging in any climate.

The new integrated thermal sensor automatically monitors and adjusts the charging cycle based on fluctuations of ambient temperature, limiting the chance of under-charging or over-charging, providing a more accurate and fully charged battery. Avoids under-charging in cold weather down to -4°F and avoids over-charging in hot weather up to 104°F.

Bring Batteries Back to Life

Reverse the effects of sulfation.

The GENPRO10X2 automatically detects sulfation/acid stratification. If any is found, the GENPRO10X2 will automatically repair and reverse the damage done to the battery, extending the usable life and increasing the performance.

Completely Automatic

Year-round charging. Zero overcharge. Auto memory.

Finally a charger from start to finish that’s completely automatic. No special modes, no technical knowledge required. Genius will safely charge any battery. Detect damaged batteries and intuitively repair them. And actively monitor for long-term battery maintenance and extend battery life. This system allows for continuous operation without user intervention, and zero risk of overcharging your battery.

Advanced Diagnostics

Know your battery's condition at all times.

The GENPROX2 has indicators to inform you quickly if the battery voltage is too high, the battery has a short or will not hold a charge, and if the charger is connected in reverse.

Tech Tip: Using A Multi-Bank Charger

Each bank of this charger is 10 amps. Combined, this is an output of 20 amps (2 banks of 10 amps each). This is commonly used in two ways:

  • Connect each bank to separate battery systems, charging both by 10 amps each.
  • Connect both amps to the same battery system, charging it by 20 amps total.

Very easy to install and it is very nice to only have to plug it in when I come home from fishing

My old marine charger went bad for some unknown reason and I was expecting to have a considerable expense to replace it. The NOCO 12V 20A was exactly what I needed to replace the old one ... but at a price that didn't break the bank. It installed quickly and easily and, hopefully, is continuing to do its job as i write this review. Good product (so far) at a good price.

Bought a NOCO 12 Volt, 20 Amp Genius 2 Bank Battery Charger for my bass boat. Easy install and works great. So I had to have one for my ski boat.

Had it about 1 month, and it works great. I have 2 new size 29 batteries that I used for 8 hours on my trolling motor, and it took only 2 hours to full charge. It is a good idea to use an extention cord that is 10 GAGE.
