OREI Switzerland Power Plug Adapter, 2 in 1 USA Grounded Connection - Universal Socket - Type J - 4 Pack - Perfect for Cell Phones, Laptops, Chargers & More

These plug converters worked great, no issues whatsoever. I dropped them a few times on the hard floor but there was no damage to the converters

The plug system is a type J in Switzerland is like a honeycomb of 3 in a circle. This isn't standard on most travel adapters or makes it difficult if using a square adapter. The small frame of these allow you to use more than one plug for more devices and are reasonably priced. I also found the plug-in to be a snug fit. The problem I find with most adapters is the plug-ins are loose and fall out.

Just what was needed in Switzerland. The four units allowed me to keep one in my backpack if I needed a charge on the road and I could use several different outlets in the hotels. No problem with inserting or removing the plugs. They fit perfectly into every outlet due to the design of the casing inserting into the outlet as well as the prongs...making a more secure connection. Good product.

these are the perfect adaptors for switzerland, which has its own unique type plugs! each one is also a double adaptor as it has a plug in on side of adaptor as well.they are plastic, but rugged enough and held up well for 20 days travel. they also did well in the recessed type of plugs you find in some bathrooms there. I didn't really need all four, but price was right. some hotels will loan you one, but many charge 5 euros to purchase one from them!. They are also more expensive if you buy them individually in the shops there!. BTW you can also use your europe two slim round prong adaptors in most of the hotels, but then they are not grounded.. was very happy with my purchase

Pros:- They work.- One adapter can accommodate two US plugs at once (one two-prong and one three-prong).Cons:- As others noted they don't fit perfectly into the socket; it requires some effort to plug them in.- One of those adapters will block all three sockets in the standard 3-way socket.- Some US plugs fit a little loose into the adapter's socket. I had a bulky charger fall out from the adapter.Strangely, those are well-made, but not so well-designed. Feels like the designers knew a lot about designing adapters, but never been to Switzerland to test them :)But overall I'm satisfied with this purchase, especially at this price.

The seller needs to updated their photo of the adapter because it is hexagonal shape which fits the Switzerland outlets perfectly. Before buying the item, I was worried that the round shape was not going to fit well. However, when I received the item, it is hexagonal as pictured. I needed this particular adapter because I had items that I needed to plug in with US prongs and European prongs. Both worked well. It was useful to have two plugs on the adapter as well.

Just travelled to Switzerland. These adapters worked well for both mobile phone and laptop.

These Swiss adapters are built very solidly, like solid blocks of plastic even though they aren't. I had no problems with the fit of either the US side or the Swiss side. So, I was very happy with this purchase. What I didn't know about the Swiss outlets is that the majority of them accepted the two prong adapters we used while in Czech Republic and Austria. The third prong is the ground. The three prong connection keeps the adapter more securely in the socket when you have an appliance plugged in, however. A good investment for the traveler.

I bought these for my ecoflow Delta 2 and these fit perfectly fine. The quality of the plastic is good and Black makes it look premium. The female ports hold onto the big chargers well. Overall its a useful addition to your travel accessories. I feel the price is exorbitantly high for the product. But similar items are not available in the local market.

Funcionaron de forma excelente, recomendables, ademas estan a muy buen precio

There were two units that came in the package. It was of very good quality and worked perfectly well on all devices we carried with us to Switzerland.

Beware, plugs/outlets in Switzerland are totally different than from the rest of Europe, I bought many adapters that said they worked in ALL of Europe but NOT ! This one IS the RIGHT one, a bit expensive but works great.

Work great.
