With the familiar sliding latch design, this adapter also covers more than 200 countries. Taller and heavier than our top pick, this is the most powerful version of the OneAdaptr to date, and it uses gallium nitride technology to deliver up to 100 watts of power. 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 100 watts of charging and both USB-A ports are 18 watts, but the total output maxes out at 100 watts, so when you plug in multiple devices, it splits between they.
Almost every charging standard you can think of is supported, including PD 3.0, QC 4+, FCP, SCP, AFC, PPS, etc., so chances are you can charge your phone with fastest possible speed. There is no ground wire, so do not plug in any devices with the third metal pin. However, there is a 10 amp fuse included with the spare fuse and the adapter complies with IEC 60884, CE and FCC standards. If you want more power or feel you could do with less, we also tested and liked OneWorld135 ($109) and OneWorld30 ($39).
Note: We tested OneAdaptr’s range extensively and found them to perform well, but the company had problems fulfilling orders and we were concerned about the number of negative reviews online. The company assured us that it has recently taken steps to improve order processing and customer service, and we will continue to monitor the situation.
