Off to Europe

This was my go to charger when I went to Europe. It worked perfect.y! I was able to charge my iPhone and iPad at the same time. Worked well for hairdryer and flat iron, making sure that appliances were ok to use in both countries. Easy to use and small/light to carry. Love it.

I bought this adapter prior to going on a six country tour of Europe and I couldn't have been more pleased! It is a great product, easy to use, extremely functional and I highly recommend it.

I have used this in multiple international & continental locations with superb success. I also have the Mac adaptor. I do not travel overnite or longer without this device. Recently loaned it to a friend traveling to SE Asia and he love it!

My other converters fall out of sockets and I have to balance them with other objects to maintain flow of electricity.

It’s great not having to carry a small bag full of assorted adapter plugs, and the USB port is wonderful.

We used this on our recent trip to England, Czech Republic and Austria. It did the job.


Work great in East Africa

Just came home from Safari in Kenya, Tanzania, and Rwanda. Thirty days of VERY limited power. When power was available I could charge 2 phones and a camera battery easily! Work well! Some adapters would not go in because of the outlets on Tanzania had a center “lump” on most plugs. I had no problems. Several other safari members took the name and plan to purchase when they get home! Great useful item.


Excellent Product

After buying several other adapters only to find them too heavy, too many pieces that were lost, and those that broke in transit; This is a pleasant discovery, Sturdy, not too large and easy to pack, all the international connections one needs...what more could you ask. Oh and the USB connections are an added plus. Recommend this product. I’ve used in South America, Europe, Middle East, >12 countries and counting.

We have used many styles and adapters in our travels around the world, but this one is the best!

It is easy to use, compact, and fool-proof.

The OneAdaptr Story

Charge 3 or 4 devices at once—in 150 countries.

Power Anywhere

Outlet-stingy hotels were a problem for OneAdaptr Maker Michael Ma. During a work trip, he and his coworkers used all the outlets in their rooms and the lobby just to charge up. Michael wanted an adapter that worked all over the world and had multiple charging ports, too. Years of planning and prototypes lead to the creation of the first TWIST World Adapter.

Since then, OneAdaptr has expanded to cover all the charging (and outlet) bases so you can travel a little smarter and a little lighter. The universal travel adapters work in over 150 countries and are super easy to use. Just pick the one
that suits your power needs and give the base a twist to raise the adapter you need. Read More Read Less
