Inverters are rated in watts.
Less than two watts for 100 mini lights.
I ran two six foot Christmas trees, about 5 100 light mini string and
four light strings off a 350 watt inverter at last years Festival of
Lights in Putnam and it didn't even breathe hard.
Have a freakin' ball with the lights. :)
Try closer to 50W for a string of 100 mini lights, unless they're the
LED type.
No way. And just to prove a point, I went out to the garage and
looked on a box of colored mini lights - 150 string.
2.4 watts.
I was a little surprised honestly, but last year I acquired a
power analyzer and ran around plugging in everything I could find in the
house. The Christmas tree with miniature lights on it was pulling around
350W, at which point I started checking individual strings. Incandescent
loads have a unity power factor, so you can measure the amp draw with
any cheap multimeter and use ohms law to calculate the watts.
Interesting - that string I ran on my truck drew less than 200 watts
total.
NO WAY

I just checked a set of icicle lights.
Individual lights =2.5V
Total of 100 lights
Fuse = 3A
No where on the package could I find watts or amps rating.
Measured draw = 300MA or 36 W
These are GE lights that I've had for at least ten years and the boxes
have the wattage rating right on them at the back.
Tell you what - I'll go down to the barn, pull out the power analyzer
and check them.
If I'm wrong, I'm wrong. I'm more than willing to admit it.
No problems. :)
Me too. :^{ )
