Review: Perfect. Easy to fix - Worked perfect. Easy to install if you can wire an outlet in you can do this.
Review: Don’t be fooled by 12v output - it’s all about the amps! - Had a hard time diagnosing the problem at first. The original unit showed 12v DC output when disconnected from the panel. So I couldn’t understand why I had dead coach batteries after 4 days with full hookup to power. I kept looking for parasitic drains all over the coach without success. After some research online, I decided to replace this component and it fixed the problem. Evidently the old unit was still making 12v DC, but at very low amps - not sure how low, but not enough! I did consider upsizing from 55 amps to 65-75 to minimize my needed daily generator hours for charging the batteries while boon docking. Because space is at such a premium (as you can see in the photo) I decided to stay at 55 amps and retrofit all the interior lights to LED (22 in all) to lower the 12v load instead. This new unit was a direct replacement under the bed in my Fleetwood 31N Tioga Ranger. Receptacle plug for 120v AC power, 2 - connector lugs for the 12v DC power and a ground wire. Easy install and it works great. Hope the new one lasts as long as the original. I’m a happy camper now.

### ⭐⭐⭐⭐⭐ Ham radio, ok, good to go with this unit!
*by J***S on July 29, 2022*

I had an accident and had lots of physical damage to my left shoulder, crushed wrist and had to have a pin put in left hip. So my wife with my talking her thru it installed this new charger and a new AGM battery. Coleman's camper Co installed originally a single stage Non-FCC approved charger. After that one burnt up 2 batteries in 5 years I decided to upgrade. Coleman does not care that their oem charger thrashes any communications equipment operating near them. My wife had to also install a female 120vac connection for the new charger. This was done by cutting off the wired in cables to the old charger. Then putting the female connector one them, Green, White and Black. The new charger works great and has no radio interface on two way radios. 73 Jimmy, wx9dx
