Having purchased and used several NOCO products both personally and professionally I can honestly say the quality of these products are second to none. The chargers, boosters, and accessories along with the outstanding customer service of Battery Mart are a winning combination.

Does exactly what is should!

I used this on my 2 boat batteries. It took a while to charge the first time, but that was probably due to low battery charge. Once I hooked batteries up, it began charging. Turns green when charged. Works exactly as advertised. So much better than manually hooking a charger every time I return home from fishing. Now, I just plug it up and forget it until I go fishing again.
