Genius GENPRO10X2: 2-Bank, 20A Onboard Battery Charger - 10A Per Bank, 12V Waterproof Marine Charger with Overcharge Protection & Temperature Compensation – for Lead-Acid & Lithium Batteries

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.

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

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 was using this system to charge two lead batteries and now I am switching to a lithium in my boat. the value of it and use is makes it super easy to use and offers a great charge. it gives options to charge lithium which when I bought was not really looking for but glad it has the feature. it is pretty bulky and a bit heavy but for what is is doing its working. have had no issues leaving it plugged in for a two days

Works great.... It has extended the life of my tractor battery (5yrs old and going strong).

I purchased this one for my Yamaha 252 boat and loved it. Easy to set up and very well made. Recommended 100%

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

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%!

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.
