Power Up Anywhere With the Best Travel Adapters

With a familiar sliding pin design, this adapter also covers more than 200 countries. Taller and heavier than our top pick, this is OneAdaptr’s most powerful release to date, and it employs gallium nitride technology to deliver up to 100 watts. Aside from the universal AC outlet, you will find two USB-C ports and two USB-A ports on the bottom. Both USB-C ports offer 100-watt charging, and both USB-A ports are 18 watts, but 100 watts is the maximum in total, so when you plug in multiple devices, it divides between them.

Almost every charging standard you can think of is supported, including PD 3.0, QC 4+, FCP, SCP, AFC, PPS, and more, so there’s a good chance you can charge your phone at the fastest rate possible. There is no grounding, so don’t plug in any gadget with a third metal pin. But there is a 10-amp fuse with a spare included, and this adapter conforms to IEC 60884, CE, and FCC standards. If you want more power or feel you can make do with less, we also tested and liked the OneWorld135 ($109) and the OneWorld30 ($39).

Note: We have tested OneAdaptr’s range extensively and found they work well, but the company has had issues fulfilling orders, and we are concerned about the volume of negative reviews online. The company assured us that it has recently taken steps to improve fulfilment and customer service, and we will continue to monitor the situation.
