Review on ⚡️ Optimized for SEO: ProMariner ProSport HD 20A Triple Bank Waterproof Marine Battery Charger, Model 44021 by Jeremy Gulledge

I returned this unit because it would not turn on. However, they have a major internal failure problem after about a year of use. There can be no user abuse as all the wires going to your batteries have fuses. Any wrong action on the part of the consumer should result in a blown fuse. This company needs to know that there are flaws in their design. I have a $20 charger that's 15 years old and still works great. I had 2 of these and both died just over a year after purchase. The third was DOA so I reject that brand!
