Review on 🔋 Progressive Dynamics PD9260CV Inteli-Power 9200 Series Converter/Charger: 60 Amp with Charge Wizard by Johnny Price

The funny thing is that the fan is incredibly quiet, but when the fan stops, the device hums for a while. Then it hums for a long time until the fan starts up. Once the fan kicks in, it's very quiet. That would be nice, but happens at intervals of about 1-2 minutes after the device has warmed up. I sent the first one back to PD. Customer service is excellent. They sent replacements with no problems. The problem is that the second block is worse! I will not go for the third block as shipping is too expensive. I'll use this to anchor the boat and call it a lesson learned. All the rave reviews about this device are misleading. I think if it was installed in the basement of the fifth wheel where it wouldn't be heard then everything would probably be fine. However, buzzing and electronics usually indicate that failure is imminent. I will replace it with IOTA and keep my fingers crossed. Again, the people at PD are amazing! goods, not so much.
