I found another thread about all the electric kitchen gadgetry people carry around with them in their RVs and there were some questions about how much power certain appliances draw (as expressed in Watts)
So I dug up this little chart.
A few caveats...
1. This chart is for a stick house, not an RV, so be mindful some stuff is not applicable. (except to your house)
2. All these appliances are AC power, no 12 volt DC stuff here.
3. Your toothbrush might actually use 50 watts, but only for the few minutes you use it. Keep time of use in mind when reading the chart.
Hopefully your computer will open the document...
