NOCO Genius GEN5X2 Review

I’m absolutely blown away by the NOCO Genius GEN5X2, a game-changing onboard marine battery charger that’s packed with features to keep your boat’s batteries running smoothly. As a two-bank charger, it can handle up to 10 amps of power, split evenly between the two banks, making it perfect for larger boats or those with multiple battery systems.

One of the standout features is its charging modes – you can select from 12V, 12V AGM, 12V Lithium, and even a special Repair Mode to get your batteries back up and running. Plus, it’s designed to work with both lead-acid and lithium-ion batteries, making it an incredibly versatile solution.

But what really impresses me is the GEN5X2’s attention to detail – like its integrated thermal sensor that adjusts charging levels based on ambient temperature, eliminating over-charging in hot climates or under-charging in cold ones. And if you’ve got a dead battery, don’t worry; this charger can revive it from as low as 1-volt.

  • 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.
