I am trying to find a chart or something that will tell me the amp draw for all of my lights / ac / fridge/ etc... anyone know of something... this is for my Lil' Snoozy

You will need to look up each item in the MFG data for both 12 VDC and 120 VAC. You can also measure both with cheap meters. If you divide the watts by the voltage you will also get the amps. If you're doing this for solar you will want LED lights, they use very little power and run the refrigerator on gas.
I cannot find data I trust on my own lights, the sellers are posting the wattage as a brightness not a power use.

Put a Kill-A-Watt meter in line with your trailer. With a fully charged battery, note the watts used by the converter when it's just idling along. Turn on items one at a time and note increased wattage use. The converter is efficient enough that you'll get a pretty close reading for 12V items. For those that use 110AC, turn off the converter and you'll know exactly what the draw for each item is.

If you want to measure, rather than calculate your load, you can get a DC amp probe meter and simply read it out without any electrical connections at all. It closes around the load carrying wire and reads the current, without affecting the wire at all.

I did find this. They are the 30 lights that I added to my F150. (not a video)

Hi George,

I can tell you that the 12V switches in the Lil Snoozy that have the cute, lighted, Snoozy logo engraved in them use about 0.2 amps each! I noticed it when we toured the floor model at the factory before we bought - the switches are warm to the touch. They really add up if you are boondocking. Just the main power switch by the door, for 24 hours, will use 5 amp-hours. I replaced all mine with LED rocker switches.

Anyone who wants my old ones can have them.
