Unidapt Universal Travel Adapter, International Plug Adapter Fast 2,4A 4-USB European Power Plug, AC Wall Charger - Worldwide Outlet for Europe US USA UK EU AUS, Blue

Wasn't sure if it would work as I hear rattling inside when I shake it. Tried it in UK and EU and perfect connection. A bit heavier than the ones I usually bring but this is great for all travels.

Used this on a trip across the EU and couldn't be happier. Four sliders push out whatever connector you need, and the opposite side is a universal plug. Mates anything to anything. The 4 USB slots allow me to charge 2 devices at once using a shared rail (aka, you'll get slow charging if you load everything up but that's normal). The only minor complaint is that the sliders don't always lock very well or play nice when switching from one to the other, but really I only need to fiddle with it once per country so before I've had a chance to feel frustrated it finally clicks into place and everything is wonderful. For the price, that's perfectly acceptable. Just hold your thumb on the slider of your choice if it isn't quite locking in place, and that's more than enough to ensure it goes into the wall firmly.

Bought it for travel to Ireland. Worked great and would highly recommend this product.

This ADAPTER (not a voltage converter) works fine. What I found a bit frustrating was that the sliders sometimes got stuck and I would have to futz around with it to get them to push out completely. The other thing to note is that especially in France, some of the outlets are set into the wall and this won't fit. Luckily I had a single France adapter with me. I'm not sorry I got it, because of the multitude of plugs on it, but I'm also not sure I would recommend it 100%. I do like the USB capability. I bought it because it was recommended on Buzzfeed.

Within our family, someone seems to be traveling internationally at least once a year. I purchased one of these several years ago. This device has the capability to plug into almost any power socket in the world and deliver 4 USB (type A) ports. They aren't high speed charging, but will fully charge my iPhone or even iPad in a matter of hours. It also will deliver AC to whatever plug type you need. For instance, travel in Europe, AC power is delivered via two round pins on the wall within a round plug. Then allow me to plug in an appliance or charging adapter with the US two blade configuration. Note: The doesn't convert power, just the plug. Most of the world runs on 240V AC, while the US is 120V AC. However, most charging adapters, and even some razors and hair dryers will run on 120 or 240. You just need to read the specs before you go. Overall, a great value for such a versatile device.

I took this with me for a month in UK, Denmark and Bulgaria. All of my relatives who live in those places were fairly impressed. It worked wonderfully. Not too big, but also big enough that it was easy to locate in the dark, groping around a carry-on. Highly recommend.

I’ve had this for a year. After Just returning from Italy with it, I had to read this rave review. I think the construction is durable. But if it were to fail, I would simply buy another one. I like it that much. Here are my reasons you want this. Reason one - because it’s a multi country adapter both in and out, you can take an outlet that already has a light plug into it, plug the adapter into the wall, and then plug the light into the adapter. See my photo of this in Italy. The result is that no matter what kind of power you’re looking at you can get the USB charging ports without losing an outlet. This is particularly nice for being able to keep things like your phone and watch right next to the bed, where there are often limited outlets. Reason two - In Italy there are frequently two problems with adapters. Some of the outlets have switches immediately next to the outlet and a normal adapter will prevent one of the switches from working. Because the southern European plugs extend out extra long on a very thin probe the adapter stands over switches of this tape. See my photo for an example. Reason three - This is another use for the same long extension plug in southern Europe. Many outlets come with a recessed round leading to the outlet. They are designed to take a perfectly round plug. Many adapters with that plug into them properly. But this one can reach in without a problem. Reason four - I tried using this plug for an airplane simply using the American style plug. It fell out multiple times, as many other chargers would do the same after being jostled around and plugged into a not very tight outlet. It occurred to me to shift to the UK style three prong plug which locks in very firmly. So this adapter will work on an airplane where an ordinary American adapter might fail. Reason five - The four USB outlets are great for today’s travel. I charge my watch, my phone, my Kindle, my iPad, and my headphones. These days almost all charging can be done from a USB. And this is allows me to charge almost everything at once.

This is one truly neat device. We are traveling. A week before we left I packed the travel bag I keep full of heavy adapters, plugs for European outlets, and plugs for the USB cords. A day later I realized that I needed another adapter and ordered this one from Amazon. It arrived the next day. It is now beside me in Seville and my travel bag with all its stuff is still in my suitcase. The device is very light. You can plug it into any outlet apparently in the world without special plugs or adapters. You just pick a slide for where you are, slide it down and on the opposite side appears a plug suitable for that country’s outlets. Once you plug in the device, you can then plug any kind of plug into its other side. The really wonderful feature of it is that there are 4 USB ports on the top. And the ports are illuminated by a blue light so that you can plug into them in the dark. So this one, very light little device does every thing I need and next time I travel abroad I can leave my travel bag of adapters and plugs at home.
