Is the item 110V or 220V?

It is 110v. Be careful if you buy this heater: Mine (and others-read reviews) worked well for a year and then overheated killing all my fish.

110.. Mine worked for 6 years and then died BUT IT DIDN"T overheat.. It just wouldn't keep the aquarium warm anymore.. None of my fish died and if you are checking it daily it shouldn't be an issue.. I believe these are great heaters! I now have another that is 1 and a half years old

It's 125v because it plugs into the wall just like any other kitchen appliance or even your clock radio. 220v is like an electric dryer, stove, water heater or furnace.

110. But the USB unit was very cheap and was not providing power to devices. I returned the item

The exact voltage has to be somewhere on the electrical item. If it's dual voltage, it will say 110v-220v. If it doesn't have both, it's not dual.

Mine took 110 volts. I don't remember if it also worked on 220 volts. Anyway the ac adapter didn't last long and I had to replace it with one I bought on Amazon.

It's 110-240 V. I've been using it in China, of which the supply voltage is 220 volts.

I bought one off of Amazon, it is 110v/60hz with a NEMA 1-15P ungrounded plug. If you're in the US, 220 is a different plug configuration.

110V, you need a step down converter to use it with 220V. Don't get caught, I did.

It is 110V. It may be able to be converted to 220V but I am not sure. I hope it helps.

It is 110. However I do not recommend it. It does not heat much to really cook well.

It is 110 volt. It is very cheaply made and holds about 60 empty cases. The "free media" that comes with it is ground-untreated corn cob. Not an item for heavy use.

This one is 110V. Been very pleased with it so far, I have had it for about 3 weeks now.

I use the AC adapter that came with the unit and it works fine...not sure if it's 110v or 220v.

Nominally it's 110v. I see no provision to change to ~220v. I assume, if you order one for use in Europe, it will come that way.

110v with US outlet connector. It will not work in Europe unless you have a power convertor and a plug adapter.

Just 110v. I know because I ruined mine. I just had to buy a new adapter; not expensive.

Since the product I have is sold here, in the US it is 110 volts. standard plug.
