Reviews around build (5.00 of 5)

  • Now.. besides this, it is very heavy duty, very well built and wired, and required no modifications* to install it.*For my application I need to lengthen one set of the leads about 18" to reach around to the other battery.
  • Can't recommend these, which is unfortunate, since they seem to be well built.
  • The enclosure is larger than I expected, but very well built and sealed.
  • I looked all over the place for a well built, highly rated, marine charger that had the ability to charge multiple types of batteries
  • it works as advertised and has a solid well built feel to it

Reviews around advertise (4.72 of 5)

  • This charger is compact, lightweight, easy to install and works as advertised.
  • It works as it should as of this time and is simple to install..
  • I usually do not write these reviews, but it has bothered me to no end, the charger works as advertised on the one bank, since the wiring broke off on the other bank, this charger has the worst quality stiff plastic wiring imagine the stiffest wire you ever came across and then leave it in the freezer over night
  • Works as it should and customer service is among the best I have every talked to.
  • This is blatant false advertising, and I couldn't be more disappointed with this experience

Reviews around charge (4.01 of 5)

  • I have it installed in my boat and leaves a good charge on my batteries
  • We have a lawn mower with a battery that is on its last leg, the little charger did the job, gave the battery a good, full charge and was very easy to use.
  • Because of its smart charging circuits, I don't have to worry about over charging my battery
  • It easily slow charges my deep cycle marine battery on my Jon boat then keeps a maintenance charge on it over the winter.
  • It's not a speed charger or one boasting super powers, but it seems to put in a solid slow charge that's good for your battery.

Reviews around light (3.86 of 5)

  • It gave no warning of failure, no smoke or odd lights or heat

  • I got a blinking red led light (it should be a steady red light - indicating that it is
  • easy to mount comes with everything, plugin cord is short but thats probably a good thing, red light for charging and green for done
