Reviews around time (5.00 of 5)
-
Used it a couple times to charge low batteries and it worked great.
-
It may not bring a car battery back from a complete drain (if that’s your need, you need a charger that can put out at least 15 amps for a reasonable charge time that can recharge just about any size car battery) but works great to maintain and even recharge a half dead battery
-
intelligent charge makes it idiot proof~~ have used this several times, always fast and accurate charges.well worth the money spent !

Reviews around quality (3.78 of 5)
-
No issues to date and the build quality is top notch.
-
However, the wires used are of inferior quality
-
To NOCO: For the price of the unit, you could use a better quality (flexible at cold) insulation on the wires
-
Just plain excellent, cannot say that enough, high quality product.
-
Noco puts these in a durable looking case, but the insides are poor quality - even by Chinese standards
