GENPRO10X2 12V 20A 2-Bank OnBoard Marine Battery Charger & Maintainer | Charges 2 Batteries at Once, IP68 Waterproof, Overcharge Protection, Temperature Compensation, For Lead-Acid & Lithium

I purchased a new to me boat that has two batteries. I had an onboard charger on my last boat that worked great. I didn't get the same one because I found this one from NOCO. They just make solid stuff. So I went with this and haven't regretted it. I also purchased the cable connector that allows you to install it in the bulkhead and simply run an extension cord to the connection. Keeps it very clean and professional. This charger, however, works like a champ. Provides plenty of power to keep my batteries charged and with 10A per battery, it supplies enough power to recharge a battery from dead quickly. It's just a very solid device. Easy to install and just plug and play.

I modified the eye connection to an alligator clip for easy removal because I am using this on my Ram 3500. Works as stated. No more parasitic drain or dead batteries.

This is amazing, replacement of my prior shore power dual charger, due to upgrade to Lithium ion battery for my auxiliary battery in my 1984 VW Vanagon. Paired this with a DC to DC charger and solar controller. Now, my Auxiliary battery will charge while driving, plugged in via this charger and via solar, other power sources are not available. The old lead acid battery was 6 years old, and totally dead after sitting sitting for a few months. The old battery would not change, after trying my other 2 chargers. So, did a temporary hookup with this NOCO and it brought the old battery back to life! Got it to 65%!

Very easy install and charged 4 batteries on one power bank. Had a few questions for customer service and their online chat was very helpful and easily understood. Would highly recommend for anyone with a camper as that’s why I bought it.

Upgraded my mini golf cart with this charger. It had great reviews, the company gives you a 3 year warranty as well. Small and compact. Has Pleanty of length on the leads as well. Charges my lithium ion batteries quickly.

I bought this after my Boat onboard charger stopped working 5 months ago in June without my knowledge, both of my Group 31 AGM batteries were completely dead. When I saw this unit and read the performance features that included charging Ni-Cad, AGM AND lithium batteries plus a feature that would restore completely dead batteries I decided too try this battery because I have bought 3 jump start units from NOCO with good results. I installed this unit and plugged it in and after 30hrs my bank 2 battery was completely charged. My bank 1 battery had know indication of any charging, so I thought I would be buying a replacement battery. Then I remembered this unit had a restore dead battery feature so a switched the unit to restore for bank 1. After another 10hrs bank one battery was at 80% after another 12hrs bank one was at 100%. I did a load test by running my electric trolling motor for 4hrs at 90% power the batteries never stopped giving power with the trolling motor dropping too approximately 40/50%. I plugged the charger up again and obtained 100% charging on both batteries.

Working well so far. i may need to upgrade to a 3-bank if things keep going as they are.

Easy to install simple to use charger and maintainer for my two lithium and one AGM starter battery.

This product is used to charge/maintain charge in my two boat batteries.

Funciona muy bien Carga. Rápido las baterías , continuare actualizando como funciona, A mas largo plazo

I had a hardwired charger before and this unit dose not have that option so I had to add a waterproof box for the line voltage connection, didn't want to cut the plug off as I'm sure this would void the warranty, the cables for the batteries were also too short for my desired location. Besides that, its pretty slick. Plug and play.....I get it, its waterproof so the connections are all sealed. Would of been nice if they had a hardwired version though. For the price you cant go wrong. My other unit was 4 times the price so this is still a rocking deal. The unit is very tiny and looks pretty. Charges both banks with no problem. Definitely recommend.
