What are the two voltage levels?

There are not two voltage levels. I bought it thinking it would work on a 220v plug and had to buy an adapter because it's made for a 110.

it is dual voltage, meaning that with the proper adapter it will work internationally.

The two voltage levels on the curling iron is on and off. But if your asking the mimimum and maximum heat level is 1 to 25. 25 being the very highest because it gets very hot.

220 & 110 volt. It works very well, I just got back from France & Italy, but don't forget to have the correct adapter to fit in their plugs.

120V and to be honest I returned this item. The LEDs are not as bright as you would think / want. Have a yellow hue to them v a white

It's dual voltage. I'm using it on 240 right now with nothing but an adapter for the plug.

Oh gosh, I don't even know what dual voltage means. Do you mean dual speeds?

I used 5V with no problem. Couldn;t find the specification but everything above 2.5 i think is considered a high

Both. There is a switch on the unit to indicate the input voltage. Mine came with a 110 plug, so you will just need a plug adaptor if you want to use it with 220. I have used the unit successfully with both voltages.

I think it's only 110, i saw nothing saying you could use a higher voltage.

They're different voltages. Use the one it came with. Hopefully you didn't fry it by using the wrong voltage!

5v500Ma, from the bottom of the main one. However, I'm not sure if that the answer you want. I don't have the box anymore it came in.

The difference between 120V and 240V is in the configuration step shown in the figure for step 3 of the user manual; 2-wire is for 120V, 4 wire is for 240V.

USA voltage. See: http://en.wikipedia.org/wiki/Mains_electricity_by_country

The voltage is not specified in the operator instructions. The 2.1 indicators apparently refer to amperage, according to the information I discovered.

I have no idea but measure whatever setting you chose - with good voltmeter and preferably under load. This power supply puts out twice the voltage the setting indicates. Please use with caution.John

I have been asked this before. There is no information on the package regarding voltage.

I'm sorry I am not familiar with the voltage. I would suggest asking the seller of the product. Thank you.

Both voltages available. In Singapore, where I am, I had to make sure it was 220 VAC, because when we order from USA any electrical appliance, we always make sure they send to us the 220V model.

Basic 110 voltage. My fiancé has used this about every 2nd or 3rd week and loves it, highly recommend!
