6 to 20 ft works just fine It works better if you buy the Littles small mosquito trays they sell at Home Depot
It is 115v US standard.
You’re talking about a little crackling noise that it starts up that’s all it is just powering up
Yes you can 125 V is just the same as 110 is better to go up then down on the wire
They are the same
Yes ive turned it on in the daylight and it still attracts the bugs.
This item needs to be plugged into a outlet.
Why are you need to meter it for one week then multiply that each time you plug it in for a month then multiply there and you got your year and it depends on how long the extension cord is also the longer it is the more you draw but you’re not be using it every day
You will need a converter from European to American voltage if you do not have a converter you will burn it up or shorted out
Dont advise u to use it indoors. Just buy a can of Raids mosquitos spray blue can spray your room close the door for about 10b/15 minutes. Then hit the sacks. No more bites
