With a familiar sliding pin design, this adapter also covers over 200 countries. Taller and heavier than our top pick, this is OneAdaptr’s most powerful release to date and employs gallium nitride technology to deliver up to 100 watts. In addition to the universal AC outlet, you’ll find two USB-C ports and two USB-A ports on the bottom. Both USB-C ports offer 100W charging and both USB-A ports are 18W, but 100W is the maximum in total, so when you plug in multiple devices, it’s split 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’ll be able to charge your phone at the fastest speed possible. There is no ground connection, so do not connect any device with a third metal prong. But there is a 10 amp fuse with a spare included and this adapter meets IEC 60884, CE and FCC standards. If you want more power or feel like you can get by with less, we also tested and liked the One world135 ($109) and the OneWorld30 ($39).
Note: We’ve tested the OneAdaptr range extensively and found them to work well, but the company has struggled to fulfill orders and we’re concerned about the volume of negative reviews online. The company assured us that it has recently taken steps to improve compliance and customer service, and we will continue to monitor the situation.
