Review: Good Warranty. Solid build. - So far so good. Seems solid operationally. Not a bunch of superfluous screens and buttons to cause failures. Just basic controls. Seems well build with a metal case and minimal plastic. It was priced competitively. It came with a 3 year warranty which was better than others in this class that had 90 to 365 day warranties.
Review: Good charger for my Power Queen 50 ah battery - Works well with PQ 50ah battery. I agree with some others that it is noisy but that doesn’t bother me.
