We are full time RV's. Charger is lightweight and easily fit into the tight space in our RV. Installation was simple and easily used the existing wiring. Charged and maintains our 2 12v batteries very well.

Replacing an older linear 25A unit, it fit right into the available space, and could use entirely existing wiring.

If using stranded main output wire, you might want to crimp on a ferrule, as the (hex-key, not slotted or phillips) 8-32 screws that secure the wire (max. AWG 4) will tend to spread stranded wire; with solid copper this won't be an issue.

From box-open to installed and running took less than 1 hour, mostly hooking up the fuse block (see other reviews).

The Charge Wizard blinked contentedly to itself for about 48 hours, connected to my 2 Marine deep discharge batteries, then went to float. So far I haven't noticed the cooling fan running (at 30A or less). The output seems to be 13.2 VDC, with ripple under load below 120mV according to my DVM.

I bought this unit on the recommendation of two friends who use them in their RVs. They just bought the Charge Wizard plug-in units because their existing inverters had the capability built in, but my old charger was a "cheapy" that put a constant charge on the battery and shortened it's life. Haven't had it in the trailer long, but so far it works great. When I first hooked up this unit it even partially brought the old battery back to life, but ot was too far gone, so I bought a new battery. Since we use our traler infrequently, it is very important to have the battery properly charged. A new battery might only last a year or two at best without the Charge Wizard. My friends batteries are pushing 5 years. Another advantage is that when I fire up the generator out in the boonies the battery will get a fast charge automatically while I'm using the microwave or air conditioner. It was easy to hook up, and of course Amazon's low price and free shipping didn't hurt either.

Honest reviews on Progressive Dynamics PD9245CV Inteli-Power 9200 Series 45 Amp

Replacing the power converter/battery charger in a 1985 Shasta travel trailer. The old setup was 30 amps which is plenty for the minimal power needed, but this 45 amp was priced to beat, so we went with it.

We did have to do some Gerry-rigging due to the age of the old setup. We didn't replace the circuit breaker box, so we had to make some adjustments to get things hooked up with that. We also kept the individual fuse setup from the old system and that took some extra maneuvering.

This converter/charger is working great. It charges the house battery without issue. With ac hookup, we can run everything at once with no blown fuses/circuits. With battery power, we can run the water pump and lights without any issue (before, we never could get the lights to work on battery power).

One note: when inserting the wires, be very careful how much you loosen the screws. They don't unscrew all the way out, and if you unscrew them too far, they move out of alignment and strip and once that happens, there's no fixing it without taking the entire thing out and apart. (We ended up using electrical wire to overcome that little mistake but not before trying to fight it for ages).

If you're replacing a newer setup, it should be a very easy process. If you're replacing an old setup, you may need to work a bit harder, but it will work great.

this was defective out of the box, however, since we didn't know it, we assumed that something else was wrong somewhere in the trailer, by the time i had money for an electrician (after christmas) and he told me this was the problem and it had to be bad "out of the box" it had been 3 months since i bought it and they would not take it back. it never worked and im out $125 with a defective product.
