Converter question

OK,while I am pretty comfortable with body and mechanical work I must admit I dont know very much about electrical.So,here's what I've got.My Scamp has 2 12volt lights and the hood above the stove is also 12volt.The problem is,the 12volt wiring runs under the dinette seat on the non curb side and has a fuse but no converter.There are 2 12volt wires that have been cut and are just laying there.
I only use shore power but I would like to use these lights and add a porch light also.Can I add a converter without using a battery and if so,can anyone suggest a good converter that wont make a lot of noise?

Brian Bran?

What year is your Scamp?

You can just get a simple low power battery charger and use it as a power supply to run the minimal lighting you are asking about.

All a converter does is convert shore power into 12vdc and charge a battery while do it.
Obviously this is what a charger does too.

I would get a charger you can return in case it is one of the newer models that require a battery for the circuit to work but you should be able to find one that will just output 12vdc if you look around.

On the other hand it would not be a bad idea to add a battery and then have an entire 12vdc system for when it can come in handy.

I use a charger you can find at walmart for under $20.00 and you can also pick up a cheap deep cycle battery there and not spend $100.00 total.

Just food for thought?

Here this will do the trick. Amazon.com: Pyramid PS12KX 10-amp 13.8-volt Power Supply: Electronics

A smaller lighter switching supply might be better like this one. Jetstream JTMINI15 Power Supply

I'd personally go with a standard converter. You can often get a progressive dynamics converter capable of 35 amps for $99 on Ebay. It's not much more money, provides more power and willl allow you to manage a battery in the future.

Generally speaking converters make poor battery chargers. For that $100+ I can get a good smart battery charger and a power supply. Which is much better for battery than a converter. If my trailer didn't have a converter already in it would NOT put one in. Right now my battery is being kept charged with a small charger that's designed to maintain the battery.

That said. A converter might be the easier way with a battery.

To add to your portfolio of options the following two units will work as well. I just bought the 60W unit for LED lights on my house deck. Amazon.com: Waterproof LED Driver Transformer 60 Watt 12V with 3-prong Plug, 3204: Home Improvement
Amazon.com: Non Waterproof 100 Watt, Led Driver Power Supply 12 Volt DC, 3219-100w: Home Improvement
I donít know how much budget you have allocated to this project but you could just add a small converter which gives you an option to add a battery in the future. Personally I would go this route. DLS-15 15 Amp Power Converter

The two from Amazon I would be concerned about the electrical noise level. They could be quite noisy and any radio or stereo equipment could be effected.

Good point, they could be noisy, these are switching not linear power supplies.

The advantage of a converter is that they extend battery life with their desulfation cycle. I have a set of batteries on year 14. I never take them off the converter.

many converters do NOT have a desulfation cycle. By all means if you buy a converter and want to keep a battery charged make sure it has a desulfation cycle. In my case the converter installed in my 2006 Scamp does not desulfate and it under charges. I've killed two batteries in 5 years because they were kept at undercharge. I'm now using a "Batter Minder" to keep the battery charged and desulfated. Only time will tell if that will do the job or not.

The original poster also indicated that they just wanted to be able to use their 12volt stuff while plugged in.
