    5.0 out of 5 stars Great on-the-boat Charger

    K.S. · June 17, 2025

    (function() { P.when('cr-A', 'ready').execute(function(A) { if(typeof A.toggleExpanderAriaLabel === 'function') { A.toggleExpanderAriaLabel('review_text_read_more', 'Read more of this review', 'Read less of this review'); } }); })(); .review-text-read-more-expander:focus-visible { outline: 2px solid #2162a1; outline-offset: 2px; border-radius: 5px; } This is a pretty good charger, a few days before taking the boat out i'll plug this in and it'll charge up the trolling battery and the starter battery and it's ready to go. I did just get a lithium battery though 100mah which at only 5amps takes about 22 hours to charge from empty. I kind of wish it had a little more oomph.You can put both charger leads on one battery and charge at 10amps but if you bolt the connections that means getting out tools moving things around, who wants to deal with all that.But so far i've charged all 3 battery types on this charger and it's worked great on all of them. Good little unit. It remembers what the battery setting was on each power up too so you don't have to mess with picking the battery each time either.

    5.0 out of 5 stars I made a mistake

    K. · June 6, 2025

    Bought a new boat with house & starter batteries. Thought it would be great if I bought a two bank charger. Turns out the boat has an electronic battery isolator that when the starter battery is being charged it connects the house battery so it also charges. So I didn’t need a two bank charger, so I sent this one back and ordered a single bank charger.Just reminds me I need to get the full skinny before I jump into something.

    5.0 out of 5 stars Amazing battery charger

    T.S. · May 27, 2025

    What can i say. Wow, I never knew what i was missing. I bought this to charge both my batteries on my boat. All i can say is Wow. Its a smart charger which means it does all the thinking for you in the aspect of temperature, charging, and battery maintenance. No regrets even though the price was a little steep.

    5.0 out of 5 stars Great product

    C.B. · June 12, 2025

    Works great and I like that it shows you battery percentage somewhat it has a 3 bar light but most don’t so it’s nice.

    4.0 out of 5 stars Potential Issue w/ 1 Bank Failing For Some but Great Warranty

    h. · June 1, 2024

    First off, this is my 6th NOCO product and all have been awesome. Great chargers, boosters, etc. Quality and performance has been superb! This GEN 5X2 forced me to have to use their customer service, warranty, etc. which has also been stellar.These GEN 5X2 dual bank chargers seem to have a common issue with one of the banks failing. One bank, mine was the second bank that failed, blinks between the charge bar and the standby lights. No matter the battery, the fuse, the connection, etc. A way to test it is to use a multi-meter to test for continuity between the positive and/or negative battery lead on that bank with the a/c power cord prongs - all disconnected, unplugged, no power, etc. The good bank will have some continuity like 36-37ohms. The bad bank will have nothing, pure open circuit.If it happens within the return with Bolo then use that. Otherwise, if its under the 3yr warranty then use no.co site to contact customer service for a warranty claim. Mine was after the 30 day return window. Initially buying it we only had one battery on our boat, knowing we were getting a second house battery. A couple months later we installed a second house battery on our boat and connecting the second charger bank, it immediately started the dreaded blink between the first charge indicator and the standby light, so that bank never worked. Not sure it is an immediate fail for others but was for ours.NOCO customer service was quick and easy. I reached out late at night with their request a call option on their website. The next day got a couple calls because I didn't have my phone near me, an email with troubleshooting steps, and next steps for a warranty claim. They'll let you ship it in and wait for a return after receiving and testing the failed unit. Or, they'll let you buy a replacement from their website - which was cheaper than here on Bolo - and refund the purchase once they've receive the return faulty unit and test it to verify the unit is faulty. I chose this option for a quicker replacement.4 stars mainly for the unit failing but definitely love their products and am now a fan of their customer service. I'll follow up with review if the replacement unit fails and drop stars. If all is well, I think 4 is sufficient for an otherwise great product and company but consideration for this mishap.

    5.0 out of 5 stars Works great !

    Great for folks who don't get out every week. Keeps those batteries charged up.

    (function() { P.when('cr-A', 'ready').execute(function(A) { if(typeof A.toggleExpanderAriaLabel === 'function') { A.toggleExpanderAriaLabel('review_text_read_more', 'Read more of this review', 'Read less of this review'); } }); })(); .review-text-read-more-expander:focus-visible { outline: 2px solid #2162a1; outline-offset: 2px; border-radius: 5px; } I purchased this devise to charge both a lead acid battery and a lithium battery at the same time. My initial use was to charge the lithium. It was easy to connect with a permanent connection and all I had to do was plug it in and toggle the button to the lithium battery mode and let it do its thing. Once charged I unplugged it and then the next day I plugged it in again and went right to the same mode and charged it and then maintained the charge. This is my ultimate plan once I mount it to my boat so I can charge it in its slip during the summer months. I have not tried to charge both at the same time however will try and update the review at that time. So far it seems to be well worth the price investment and pretty crazy at how flexible it is with multiple charging option requirements. Highly recommend at this point.

    24Vで動く装置のバッテリーを充電する為に購入しました直列に2個繋がれた12Vのバッテリーをそれぞれ監視しながら充電する為安心です各ケーブルにはFUSEも付いていますバッテリーのタイプも選択できるし充電状態の表示も有るので安心です船などで使うように設計されているようで本体の作りも頑丈です過酷な環境でも長持ちする事を期待します

    Very High Quality

    A.S. · April 13, 2022

    Fitted this in my boat, (as it has 2 batteries). It's an extremely high quality product that keeps the batteries in tip top shape via the mains. I'll be hooking it up to a solar panel next, so I'll update here when I know the results.

    My problem with it

    s.f. · November 28, 2024

    My problem with it that it doesn't come with quick connect end, only with terminals. Not sure what am I going to solve this problem now as all my cars are with quick connect.Other than that, this's my third NOCO charger so it's amazing.
