Question: Can you plug a 3 to 2 prong converter into this item?
Document: I bought this for a trip to Stockholm. It feels like quality construction and it worked well for me. When plugged into a wall outlet, the adapter fits snugly. It has one socket for 2/3 prong US plugs and another that accepts only 2-prong.
Have not found a better adapter anywhere, and the color is pretty cool. Also, thanks for the great service, I received the item within 3 days! Going to use it in France and Istanbul, and will be ordering more when the family comes along.
Used this item regularly during a 2+ week trip traveling through Norway. As I made this trip with a backpack, weighing less than 20 pounds, I had to be very selective about what I carried. This was a perfect choice! I was able to charge two electronic items (cell, camera, etc.) at the same time from one outlet, which was great since hostels don't have an abundance of outlets.
I purchased two of these for (1) the extra peace of mind that it had surge protection built in, (2) that it was a bright color, and therefore not easily forgotten and left behind, (3) and that it had two outlets. They arrived very quickly. When it arrived there weren't any markings or rating as to the surge protection, nor could I see any surge protection component through the semitransparent case.
Purchased this product for a recent trip to France and it worked great! It fit all wall plugs in all hotels with no problems. I did, however,  only plug a power strip into the adapter and used the power strip for battery chargers, hair dryers, etc. Another advantage of this adapter that i didn't see on all adapters considered was the ability to connect a two or three prong US plug.
i have an appliance that i purchased in Korea, along with a separate voltage converter. unfortunately i forgot the adapter in Korea. the voltage converter plugged into an American socket but i needed a way to plug the appliance into the converter so i bought this to use and it worked. korean appliance --&lt; this adapter >--&lt; voltage converter --&lt; american socket
Simple review...worked on every plug at every hotel I stayed at in Turkey. I was really confused shopping ahead of time at what plug to get but this did the trick. All my electronics (camera, phone, tablet)were dual voltage so I didn't need a more substantial converter. I bough a backup in a different brand but never needed it.
Why so many ecstatic reviews about a plug adapter? And you have to choose to read the right one to find out that this "adapter" just adapts the plug design, nothing else. I thought I'd found a lightweight, inexpensive voltage converter, which would explain all the 5-star reviews. But no:  they're ecstatic about a common plug adapter, the sole advantage being that it can accommodate more than one device at a time.
I took the advice of many reviews I read to not buy a cheap adaptor. Bought this even though it was painful to pay almost as much in shipping as what the thing cost. It was worth every penny. It has TWO plug in spots so you can charge your phone and camera at the same time on one adaptor. Worked beautifully in Tahiti and Bora Bora. No converter is needed. Used Hair dryer and flat iron with this as well.
!PREVIOUS REVIEWI went back and reviewed the description to confirm what I'm saying here, but there is no disclaimer in the description of this item to the effect this thing doesn't do anything other than allow you to plug something into a receptacle in Europe and promptly blow your appliance up. This thing only allows you to plug something into an outlet with 220V....it doesn't change the voltage. What are they thinking?
Answer: yes, it has both 2 prong and 3 prong sockets on the same unit. So assuming the current & power draw is within limits, you might be able to put two pieces of equipment on the same unit if needed..
