- Reviewed in Canada on January 6, 2025Verified PurchaseUsed this for my two 6V RV batteries and worked great! Both were quite dead (came up as under 25%) and this brought both back up to full charge in less than a day! Just plug it in, set it to the right type of battery and let it go. Easy to use, small, and a great value. Love it and would recommend.

- Reviewed in Canada on April 29, 2023Verified PurchaseThis is a well designed and built battery charger, can be wired to a battery bank and then you can forget about it, just plug it in when needed. The problem is the way it’s shipped, it comes with multiple cords designed for most countries around the world, I will not be travelling with my charger. The output leads are also way too long and the unit was packed in 3 layers of cardboard. All this excess makes the product more expensive, and wasteful.

- Reviewed in Canada on September 3, 2023Verified PurchaseGreat little unit, I just finished mounting it in shed in my back yard. I plan on leaving my two boat batteries there during the winter. I was a pain to hull my boat batteries to my house and down into the basement to charge them and on single charger once a month. Now I can just connect them and forget them until next Spring.

5.0 out of 5 stars Great so far.
Verified PurchaseI've always used Battery Tender in the past. After a lot of online research I decided to give Noco a try based on the additional features it has over Battery Tender. I've been using it for a little over a week now and it's been great at maintaining and charging my 2 motorcycle batteries. My only complaint is the proprietary charging cables. Had to fork out and additional $35 for 2 of the standard adapters. No big deal... Just an inconvenience. Both of my motorcycle came with the standard charging cable pre installed from factory.
JamesGreat so far.
