you get an adapter
No, that is a good use for for that plug.
Power is multiplication of voltage and current. You need to know the load current drawing to establish the power. It is a bad idea to use 230 v adapter in 120 volts outlet
Ummm yes ? If your talking about a wall outlet yes you can have 120v dc but not at an outlet
No you cannot plug a 100v into a 120v outlet, it will fry whatever the product you are plugging up.
In the US on an 120v 15a outlet it's the short slot
Yes, assuming the wall outlet produces 120V 60 Hz at at least 4 watts.
Yes, It is only when you try and connect a device that draws more that 1000mA will you get into trouble, as 1000mA is the load limit the power adapter is designed for.
Check the wattage of the device that plugs into the adapter. If the device's wattage is lower that 25 watts then the answer is yes. If the device's wattage is higher that 25 watts then the answer is no.
Yes, no problem at all.
Yes. It's functionally the same.
yes ofcourse they both are the same
You will burn up your appliance!!!!!
Don't be stupid. No.
If you need to ask, you should have someone who knows how do it....
In the US, standard household receptacles are 120V, but historically they used to be called 110V. So the two are the same thing - at least in the US. Depending on the age of the electrical device the nameplate may say: 110v 115v 117v 120v and they all are referring to a standard household receptacle.
No, different pin configurations.
yes. but DO NOT do it the other way.
Off hand no but your explanations are not clear as to who is doing what to whom,,
a DC adapter reduces 110/120V current down to (usually) 12volts pf current.
You should have no problem as long as the pug fits into the outlet. Common house hold voltages range up to 120V.
