Progressive Dynamics PD9270V Inteli-Power 9200 Series Converter/Charger with Charge Wizard - 70 Amp

So, I circle back around to write a review, haha. 2016 I bought this to replace essentially the same model (older model same brand). The price then was about 200 less than it is on amazon now, thats kinda crazy. But, i have found this is a decent converter/charger. Keep it from being baked in the battery compartment and I would say it will last quite some time (why so many RVs just have a sealed off box with no ventilation is sad). I attribute my batteries still being alive to this thing. MFG 2015 still working great today, regular 12v deep cycle pop cap lead acid batteries. I also have a DIY lifepo4 12v battery I can hook up to this thing and cycle it to the solid-light (fast charge?) state and it ripps around 900 watts into that battery at 14.4 v quick. My only complaint and/or caution is this, do the math on the efficency. The input wattage and output wattage are quite different placing efficiency low. That extra electricity cost for when it is running full blast vs the cost of replacing batteries every 2 to 3 years.... may be worth doing the math on that but for now I will likely just get another one of these when it takes a dump. The cycling between different states of charge/float/etc are what makes this thing shine.

I've had three of this particular model of converter in various RVs, and they work great. I always replace the stock converter with one of these. They supply plenty of power. They are exponentially better than the generic converters most RVs are equipped with from the factory. Your lights won't dim when the furnace or pump come on, and your battery will never overcharge with a progressive dynamics converter.I am now on my fourth of this model because my third one quit. I believe it was due to moisture, but I'm not sure. I didn't take it apart because even though it was just over 2 years old, Progressive Dynamics sent me a brand new one! You can't beat that. I took a shot and emailed them to ask if it was covered, Andy replied asking for the serial# and my shipping address. 3 days later, a brand new Progressive Dynamics converter showed up! Excellent! Thank you Andy at Progressive Dynamics! If you are considering replacing the converter in your camper trailer or RV, go ahead and stop looking. Buy this one. These are also the best battery chargers or 12v power Supply on the planet.

Converter went on our FR3 motorhome right before a trip. Local RV center wanted over $500 plus tax just for the part and had to order it. Found the exact one on Amazon on a Thursday afternoon for $200 less (I get they need to make a profit, but that's quite the mark up) and had it the next day by noon when the mail lady delivered it. Working like a charm. The hardest part of installation was getting the old one out. Charged the batteries right up.

I have a (used) 2005 RV and the original unit was a cheap one used by the manufacturer to hold down costs. At best the old one had 2 stages. This one has the intelligence needed and the 3 stages claimed. As soon as I started it up, it took the batteries to 14.6 (where they'd never been with the old one). After the initial bulk charging (which took a long time), it doesn't hold the 14.6 as long as that first time. The fan is much quieter than the old one. Wiring was a simple replacement. The only hard part was access to the area (under the fridge and I'm not pulling that out!) but there was just enough: measure your access opening to make sure you can move the old & new equipment in & out. The swap out also gave me a chance to route heater ducts away from the unit (which wasn't done in the factory years ago). The remote display is comforting to show (through various blink patterns) that the unit is working properly. It also has a manual override button which I haven't used.

This product is as advertised. I actually returned this unit because I was on the road and it did not get to my delivery point on time, so it went back automatically. When I got home I reordered but got the exact same model only in the 80 Watt model. It is the same unit I found at an RV store for a $100 more in price -- sweet. Install was a breeze, same wiring as the old unit removed. The small monitoring dongle that comes with it is a nice touch but I mounted it inside the compartment with the unit. It is a small light on off, blinking type trouble shooter, that monitors if the unit is working properly or not. I installed a constant voltage monitor that reads out in number for me and use that to monitor the batteries. Still a nice addition if you need it. All of the RV resale shops are selling these so that says something -- the last thing the RV shops and stores want are a lot of returns.

Converter went out on rig and needed to replace. Instead of settling for same replacement, I upgraded to this make and model and I'm glad I did. For starters, this unit can handle more amperage (which is what my mechanic friend recommended) and has a "pendant" you plug in and can see which stage the converter is in (boost, storage, etc.). In addition to the pendant telling you which stage your converter is in, you can manually change the stage if needed simply by following the instructions. Unit was completely "plug and play" outside of drilling new mounting holes.After installing this unit (also have Progressive Dynamics surge protector), my cabin lights have never been brighter (used to go back and forth between bright and dim....thought it was campground grid) and I no longer have the inconsistent power going through my rig.If converter going out, like mine did, would definitely recommend this replacement along with surge protector....this company definitely knows what they are doing and puts out good products.

I got this in 2017 and haven’t been able to use it a whole lot but it still broke on me (I think). Right now the Boost mode light stays on at all times and I found out the hard way the unit isn’t working. I put a multimeter to it and it shows no DC power coming from it. Maybe it’s not the unit that’s broken but I can’t imagine it’s something else seeing as it was working a week ago and I haven’t moved or even really been in the RV since then.
