When I originally ordered the LG DVD player from Sears it came with a European AC adapter and I had to go to Radio Shack to get an American adapter plug to put on the AC Adapter.  I went to several electronic stores to try and fine an adapter with the US plug that would match the voltage and wattage not to mention the plug that could be use to plug to the actual DVD player in order to charge it.  Well I found this item on Amazon to replace the European version and now I can use my DVD player the way it should be used, with a US AC Adapter.

To a person who grew  up in the era when putting three plugs into a wall socket would blow a fuse, and when a 120volt to 240 volt converter weight 30 pounds and was the size of a lunchbox, this is a miracle.  Plug it into a British or German or Romanian wall plug, plug your 115-volt American or Canada gadget into it, and there you are.  No heat, no smoke, no blown fuses, not electric shocks.  Works great!  I used it in hotels and on a cruise ship on the Danube.  I recommend it.

Regardless of what others have said, this product DOES NOT CONVERT VOLTAGE. It accepts products with voltage from 100-250 but does not convert it. In other words,  if you are like me, a US resident, traveling abroad,  and you plug in a US curling iron or dryer, the product will not work if it is 120 V meant for US.  This item simply allows you to charge very low watt items such as a cell phone.

This would be more useful to me if it had the internal electronics powered by 12/24 Dc than only 110v AC.  Well built and reasonable in price.
Placed this unit on the shelf as a spare.  Just opened it up to use it and the front panel says 110-120v while the inside has 220v indicated.  Based on that I would assume that the unit is actually 220v.

Make sure you check your unit ASAP when you get it.

The adaptor for Europe is square, however, in Europe the outlets are round so it will not work.

This charger worked great, and was a good price with free shipping.  It works in the house with 110vac and in the car with 12vdc when I am out and about.  The AC plug folds down into the unit so it won't pock through the camera bag, etc.

We bought this power converter for a trip to Italy.  They use 220 volts so to plug in your 110 volt electronics, you need to reduce the  voltage.  This item worked perfectly for our two week trip.  The only thing you should realize is that it is heavy.  it probably weighs 3 to 4 pounds.

Very useful!  It's a simple product and it did what I needed.  In Brazil, some receptacles are designed for the basic two-round-pin 220 V without physical blocks.  In my hotel and other areas, the little hexagonal bit around the 3-pin plug were required for a physical connection.  And the third ground pin should protect you just a bit more.  220-v accidents tend to give a lot more jolt than 110: V-squared over R.

Just Bare in mind Power supply comes as 230V, there is a switch on the side move it to 120V. Took me a while to figure it out myself

I used with battery and 12 volt power adapter. It's better with the 12 volt supply.

This product works great for all those pesky AC adapters that don't fit right on a conventional power strip. I used this behind my LED flat screen TV to hook up all of the other components like cable box, DVD player, etc.

Works very well when connected to ~220VAC with an appropriate adapter. Just make sure any devices you plus in the outlets are rated for 110-220VAC (e.g. Apple Macbook Chargers). I use this when traveling internationally and inside data-centers, connecting to a 220VAC PDU "power strip".
