Perfect accessory for travelers to Europe
Style: Type C/G/A-Most Countries-3FT
I travel to Europe yearly, so it made sense to purchase a power strip with a type C plug rather than traveling with multiple adapters. Even with a 3-foot cord, it's the perfect travel-friendly extension cord. I love that there are three standard USA outlets, as well as two each USB-C and USB-A ports. Even better, it's lightweight and doesn't take up much room in my luggage. It's very reasonably priced, has great functionality, and I highly recommend it for fellow travelers.

Best plug if you are traveling to France or Europe
Style: Type C/G/A-Most Countries-3FT
If you ever need a European plug, this is the one to get. I took it with me to France for a whole month and it was a life saver. I was able to plug all my electronics and also have no issues with the conversion of watts. Now that I have it I take it with me anytime I travel to Europe.

Great Buy
Style: Type C/G/A-Most Countries-3FT
Bought for trip to Italy. The long cord worked great as I had several things to charge and the side tables weren't big enough. This reached the floor and nothing was falling off tables. The plug fit snugly in the socket which was key as they tend to be loose there. Don't take your own hair dryer or curling iron, they burn out from the amperage there.
