US to Japan Plug Adapter - One Beat Japan Power Travel Adapter with 3 Outlets 3 USB Ports(2 USB C), 2 Prong to 3 Prong Outlet Adapter, Type A Plug Adapter for USA to Japanese Philippines China Canada

Works good. Adapts US plugs with a ground probe to be able to plug into outlets without the third ground probe. Also has extra USB charging ports.

worked great in Ireland. My sisters bought another kind and it did not work in our hotel but this one was perfect

Worked as intended, fast arrival

Used it in New Zealand, and it worked great everywhere I went. I liked that there were USB ports directly in the plug, so therewas no need for me to bring charging bricks for my devices. I plugged them in directly to the device ad worked as intended. The plug fit perfectly, and I didn't have to worry about a loose fit like I had when i traveled to Australia with a different converter before.

Purchased for a trip back home to the UK - worked flawlessly, plugged in my phone, iPad, curling iron, portable charger at the same time with no problems at all!!

Used the plug adapter in Japan for 3 prong US conversion. It worked as expected. This was used in many hotels in Japan over a 2 week period. Depending on the outlet, the adapter tended to partially pull itself out due to the weight distribution, even without any additional cords plugged into the adapter. (other reviewers mentioned this too) This may become a problem with multiple plugs in the unit but I only had 1 or 2 things plugged into it at one time.

Worked perfectly while on my trip to NZ. I could have my computer, phone, headphones, and an additional phone charging all at once if needed. Sturdy, fit in any of my bags easily without adding any weight. Great tool for traveling to the countries that have these kind of ports

Very happy with it! Works great!
