does power converter charge battery?

Just bought a 16ft scamp with a 20 amp magnetek "power converter" under the dinette seat. Does this converter recharge battery when camper is plugged into 110. If not... do you just charge the battery before you leave,,, for when 110 is not available? Thanks... Another rookie question, i know... (fair warning,, there will be many more questions to come.. lol.) Thanks again everybody... I am just learning.

Magnetek makes both converters and converter/chargers. You would need to know the model number to be sure. I'm betting it's only a converter. What year is your Scamp?

Yes the converter charges the battery while plugged into 110.

The owners manual for your Scamp can be found here - you can download a paper copy of it. Although the items shown in the corresponding videos may look different than whats in your trailer they work pretty well the same on older models of the same items.

The easiest way to tell if the converter is charging your battery is to measure the voltage across the battery then plug in the converter and measure again. You should see an increase in battery voltage if the converter is charging. Rough numbers: 12.4-12.6 volts without. 13.5-14.5volts plugged in. If you don't own a voltmeter you can ask a friend or buy one. They cost about $20 at any hardware store or auto parts place. Raz

Carol: It depends on which converter came with his Scamp. The one in mine requires me to chose between battery and shore power. When shore power is switched on,the battery is disconnected from the 12v circuit, and the 12v circuits are run by the converter only.

Dennis I know some converters have a switch that needs to be hit when going from 12volt to 110 but are you saying that when you switch over to shower power that your battery is not being recharged - it seems odd Do you need to be plugged into 110 but switch over to 12volt in order for it to charge?

Carol: Yes, when I switch to shore power, the converter kicks in for 12v power, but the battery is isolated(as in disconnected from everything). When I switch to battery, the converter turns off. Quirky, huh.

And some converters don't do what they are supposed to do no matter what you try. The chinese made "American" brand used in later Scamps seems to be more problematic than others.
As mentioned, get a DIGITAL volt meter and measure your DC voltage with the shore power connected and disconnected. If it doesn't go up at least 1 volt when plugged in, don't expect the battery to get charged.
Look up the Progressive Dynamics PG-4045 as a replacement if yours isn't doing what you want.

Ok I will bite - how does it get charged then?

I get it that when you switch to battery power the converter turns off as its not needed and I get why it turns on when you are on shore power as it is its feeding the battery power & charging it? isnt it?

Currently, I use a separate charger, or allow the tow rig to charge while driving. Someday I'll replace the whole darn thing with something more modern(that doesn't also use glass fuses!). I don't boondock so it hasn't been a problem.

Dennis that is strange - are you sure you converter was original to the trailer. What year is yours? My 92 has its original and its a charger/converter.

This was a 'stripped' military model of the trailer-originally with no converter, or battery-just propane for the stove. The converter was added later. I have converted all inside lights to LED(and marker lights) and added additional 120v outlets. The converter is not very powerful, so it's on the 'list'.

thanks for the explanation glad to hear it wasnt a converter that was put in by Scamp originally. That would have been real strange.

The 70's Trilliums came with a converter that is so simple that if you try to charge your battery with it, your battery life may suffer. It is just a 120VAC to 12VAC transformer with a full wave bridge. This would keep charging the battery long after the battery was fully charged. Eventually it would boil the battery dry. Crude, but effective.

That is why this thread was of so much interest to me.
Trillium 4500 replacement converter?
