Compact size for easy traveling
Style: Type C Most of Europe - 3 Pack
These adapters are so handy. I purchased 4 of them for my wife and two daughters and myself to use it Iceland. Small enough to put in carry on bag. I can plug in my phone watch charger and Cpac machine with no problem. Best value for price and size.

Works great. Good value.
Style: Type C Most of Europe - 3 Pack
Great except that it should also have a European fitting so that the lamp (or whatever) can also be connected again.

Multiple Outlets in One Plug
Style: Type C Most of Europe - 3 Pack
Highly recommend these. Multiple outlets in one plug with quick charging and flexibility. Great having three of them as my husband used one, while I had another. No issues with compatibility in Paris and easy to input

Work well!
Style: Type C Most of Europe - 3 Pack
Love these! Used them all over Italy and Switzerland a bit too. Hair styling tools worked great, they never fell out of outlet. Did not overheat. Easy to pack.
