Description of ๐Ÿ”‹ NOCO Genius 4-Bank Marine Charger GENPRO10X4 - 40A (10A Per Bank), Fully-Automatic Smart 12V Onboard Battery Charger, Maintainer, Desulfator & Temperature Compensator

Multiple banks - A four-bank onboard battery charger rated a 40-amps - 10-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. Meet the all-new GENPRO10X4 - Similar to our GEN4, only better. It's 10% smaller and delivers 33% more power. It's one of the best performing onboard marine battery chargers we have ever made. Fit type: Universal Fit.

Won't turn on for two weeks after return window

Worked great until it broke. Literally two weeks into Revain's return window, it won't turn on at all. I am currently dealing with NOCO and their warranty is not an issue. That is a big problem. There are no phone numbers for support. They will not call you even if you request the call back option. They force me to buy a new one for $500 on their website, then ship the broken one and if they find it broken they refund me for the new one. I think if they say everything is fine, will I have twoโ€ฆ

Pros
  • Designed for Water - Fully sealed and waterproof IP68 rated onboard charger that has withstood rigorous life cycle testing including thousands of hours submerged.
Cons
  • boring packaging

The charger corresponds to the declared; well constructed and works well

Reading the reviews it seems that the NOCO blocks have slightly better reliability than some of the others I have reviewed. The 4 bank NOCO unit is a bit more compact (but still a LAST to install) than the Dual Pro and this proved to be a critical element of the install for me. In terms of usage, I only installed the device a few weeks ago. Charged twice, works perfectly. It can work with almost any battery on board, including lithium. I have 4 batteries on board: two deep cycle batteries, oneโ€ฆ

Pros
  • Dead Battery Charging - charges batteries up to 1 volt. Or use the all-new Force mode, which lets you take control and manually charge dead batteries to zero volts.
Cons
  • So So

The third NOCO charger.

The first genius failed and the company sent me a Heavy Duty Marine version free of charge to compensate for any inconvenience. About 4 years later we had a thunderstorm. We never suffer from them, but this storm has affected us greatly. No direct hits, but one burst of energy killed 6 power supplies, a router, a switch, almost every built-in fuse, a garage door opener, and my good marine-grade NOCO charger. I have my lawn equipment and our emergency power solutions ready. This new generationโ€ฆ

Pros
  • Multiple Batteries - Integrated charger for four batteries rated at 40A - 10A per battery - for 12 volt batteries including marine, boat, starter and deep cycle batteries.
Cons
  • Long delivery

It's worth doing sports

I bought a boat without a built-in charger. The previous owner laughed at three different chargers and attached them with alligator clips each time. I found this charger to be quite expensive, but since I'll most likely be switching to lithium batteries when they wear out, I figured I'd bite the bullet and invest in the future. I was surprised that the packaging was really pretty. It looked great. But more importantly, it was very secure and protected the product inside. It was a bit hard forโ€ฆ

Pros
  • Enjoy precise charging - the built-in thermal sensor detects the ambient temperature and adjusts the charging process to avoid overcharging in hot climates and undercharging in cold climates.
Cons
  • No automatic
