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 !

  • 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
