UnidaptUS to Europe Plug Adapter 4 Pack - Type C European Travel Converter for Italy, France, Germany, Spain - Compact USA to EU Outlet Adapter - White

Worked well on European trip. Lightweight. Necessary for recessed European outlets. Good price.

I used these adapters in several hotels in Germany and Italy. They worked perfectly. Small, lightweight. Easy to pack. Charged my iPhone just fine.

I can confirm that these plugs work in France and Switzerland (specifically Paris and Grindelwald) even though the sockets are slightly different in each country. We just used them in both locations within the last week. I recommend taking strips of duct tape to keep them secured to your plugs. They don’t stay connected well because 1) it’s necessary that the prongs are flexible and thin enough to fit the sockets with smaller holes in France compared to Switzerland, and 2) they don’t stay connected well because the combination of plugs stick too far out of the wall to reasonably be held together. This problem is easily solved with duct tape.

Adapter is compact and does what it is supposed to do.However, the grip is a little lose, so do not expect to keep heavy items plugged in. I was using to plug a phone's power bank and had to plug it onto a power strip because it would not stay on the wall outlet.

These are perfect little adapters. What most people don't realize is that most of your modern electronics are designed to take anywhere from 120V to 240V current. If it has a "wall wart" it almost certainly is designed to handle whatever you plug it into. Of course, your plug for a US device isn't the same as the plugs found in Europe. To plug it in, you need one of these simple plug converters. They're cheap and work well.You should check every device and make sure it says "120-240V input" but the only things I've found so far are big power users like hair dryers. These will draw too much power even for most of the converters you'll find online so you're better off leaving them at home and using whatever the hotel/hostel provides or buying a cheap one while you're there.I did find they will loosen up over time and not grip as well so if you're planning a longer (or permanent) stay in Europe you might want to consider unplugging them as seldom as possible or maybe splurging for a more expensive set. As it is, I'll lose these long before they're not usable and they're so cheap I'll just buy new sets as needed.Protip: if you're using many devices, you can use one of these on the wall plug of a US surge protector and then plug all your items into the surge protector. Just remember it's now 220V!

Exactly what I needed when traveling in Europe.

It was just what I needed. I recently visited Turkey and the adapter I had did not fit the outlet. My adapter was square with multiple prongs for different countries, but the outlets were round. With these adapters round or square outlets won't matter. Also the price was very reasonable for the four pack.

Not sure what kind of parallel universe these glowing reviews are coming from, but these socket adapters were borderline useless. If your goal is to not charge your devices in Europe, then congratulations you’ve found the perfect product.Tried using them with multiple USB / phone chargers, and unless you enjoy picking up your charger from the floor every five minutes, steer clear. The fit is so loose you'd think these adapters were personally offended by your charger. Half the time the adapter stayed in the wall like it was clinging to life, while the charger bailed completely. On the rare occasion it did stay connected, the whole setup dangled out of the wall like a cooked spaghetti noodle.
