PowerMax PM4B-60 Converter

I've been wanting to upgrade my battery boiler OE converter to a better quality three stage converter.

Anyone have any experience with the above mentioned converter, and have a review on it, or any other PowerMax converter?

Thanks in advance for your input.

I have the PowerMax Boondocker 45-amp converter in my Argosy. I can say that it's a VAST improvement over the WFCO converter it replaced. The voltage is stable and the converter seems to put out a decent amount of current before the fan cycles on, whereas the WFCO had enough periodic variation in the output voltage that you could see it in the lights brightening and dimming several times a minute, and turning on a light or two would set off the cooling fan on the converter even in cool weather.

So far I'm happy with the purchase.

I also just recently (about 3 weeks) put in the Boondocker 45. Like the above post it is working just fine so far. Not a bad price and 3 year guarantee not to mention about 30 lbs lighter than the solid iron block I removed. Sal

I have had very good experience with the Progressive Dynamics PD9245. It is a 3 stage 45 amp charger and is inexpensive, in the range of $140 to $200 depending on where you buy it. I have changed out 4 different RV's with the PD and each has worked faultlessly.

I have a 60 amp 3 stage Powermax Boondocker in my trailer that I installed last year. So far it has worked well. I bought it from Randy and Best Converters.

A couple of threads below, you can see where I just installed the 60-amp 4-stage. Only a single night's stay in it so far, but the instant piece of mind alone is almost worth the price. As I get more and more experience and gain more observations, I'll keep you updated, if you'd like.

No issues with the 55 amp I installed 2 months ago (I fulltime). I've only heard it twice in all that period after the initial switch on.
