For residential service 110V, 115V, 117V, 120V, and 125V are all functionally the same. Electric companies have been slowly increasing the line voltage over the last 100 years to cope with increased loads. That is where these different voltages come from.
The tolerance is generally +/-10%. That's +/- 11.5 volts in this case. So, a 115VAC appliance will run between 103.5 and 126.5VAC.
The short answer is yes. 110V appliances can work with up to 130V without being burnt, additionally, 220V appliances can work with up to 240V without being burnt.
Yes, no problem at all.
You should have no problem as long as the pug fits into the outlet. Common house hold voltages range up to 120V.
You will burn up your appliance!!!!!
you get an adapter
No. You'll need an adapter that can change voltage.
Yes you can safely do this. Most appliances that are marked 115 volts will operate on outlet between 110 and 120 volts safely.
No you cannot plug a 100v into a 120v outlet, it will fry whatever the product you are plugging up.
Any 110 volt appliance is designed to be plugged into a 120 volt outlet. 120 volt outlets generally supply between 105 and 120 volts.
The amps drawn will be cut in half but the appliance motor, if there is one, may not be able to start up and burn up.
US outlet and US air conditioner = Yes
