Highly recommended for boats
Can’t recommend the Noco genius enough. I mounted this in my boat and it works very good.!all you gotta do is plug an extension cord in and it does all the work. Makes charging batteries a breeze. Very simple to hook to battery’s.

Good quality, reasonable price.
Functions exactly as expected and I am now charging 2 trolling motor batteries and 1 boat starting battery with 1 plug into the outlet. Simple install on my duck boat. I added length to the trolling motor wires following the instructions on proper splicing location (after the in line fuse) and it works perfect. Charging 2 AGM trolling Motor batteries and 1 Standard lead acid deep cycle battery.

اقراء قبل الشراء/للتثبيت في قارب-مركبه-كرفان متنقل فقط ولا يصلح لتثبيته في كراج او مواقف خارجيه.
هذا المنتج خاص ببطاريات القوارب ويتم تثبيته داخل القوارب او داخل الكرفانات المتنقله لشحن البطاريات فقط. (لا يصلح لتثبيته في مكان ثابت مثل المواقف او كراجات منزلية لوجوب ربطه بشكل مستمر مع البطاريات الا في حال ادخلت على اسلاك التثبيت بعض التعديلات لتصبح اكثر مرونه في النقل).

So easy!
Very easy to install and get going. Took only a few minutes. Only thing I would mention, and this is from my own personal experience in the first few days, is that I have one onboard battery exclusively running my refrigerator. It draws about 4.5-5.5 Amps. The charger maintains the battery, but I have gotten a fault twice now where the charger thinks the battery is no good because it is not keeping charge (especially when the fridge is drawing more than the charger is putting in). So it faults and shuts down that line for charging and my battery discharges. When I shut the fridge off and reset the charger, it will charge that battery back up to full and no issues. So I might need to return this unit for the 10x3 unit to ensure adequate charge is available to maintain the battery with the fridge going. But awesome product and easy to install and use. I would recommend these to everyone.

Awesome Product.
I waited two seasons of charging before this review. I have multiple battery types and different requirements for charging and storing batteries charged and ready for use. This unit is literally plug and play, safe and incredibility reliable for keeping the batteries not only charged but conditioned while in storage over the winter. Highly recommend.
