[This review was collected as part of a promotion.] This is such a wonderful converter! I recently traveled through Europe and having this versatile converter was a blessing. It's easy to keep in your bag and charges phones quickly! There are 3 different adaptors you can use, including the US/AUS, EU, and UK! If you're hopping around from different countries or have layovers in the UK, this is a necessary addition! We were able to charge our phones with a US plug and we didn't have to buy any other plugs during our trip. There's also an option to plug in two USB-C plugs or a USB, which was great when traveling with others and having to charge multiple phones overnight. I would highly recommend this converter for any international travelers!
