OneWorld PD – All-In-One world adapter review

oneworld PD oneadaptr travel adapter review

OneWorld PD travel adapter, at rest, and in action!

OneAdaptr OneWorld PD is a travel adapter that works in 150 countries. It has 3 USB-A ports, a USB-C port, and an AC charging port.

I like to travel light, and a good chunk of my packing space is taken up by my devices—usually phone, laptop, and iPad Pro though I sometimes carry a tablet with a screen to connect it to my laptop.


Here you can see the overcurrent protector button.

Even worse, a lot of that baggage weight comes from the bulky chargers. At times I’ve forgotten a charger and ended up spending a lot to buy a new one, not to mention the time and inconvenience involved in that. So an international charging hub is an ideal solution–a space, weight, and moneysaver. The current (Feb. 2022) price, direct from OneAdaptr is $49.99.

Disclosure: I received a free sample from the company for review.

The OneWorld PD provides that central location to do it all. You can charge up to 5 devices at once, including a phone, laptop, tablet, plus things like hair dryers, steamers, irons, and all that other stuff that comes in handy for business or leisure travel.

It handles up to 10A continuous AC power consumption and automatically shuts down if there’s an overcurrent.

Product overview page with all the deets.

Although I can only test this in the U.S. at the moment, it works well for my USB-C, AC, and USB 2.0 devices. Its compact size and light weight make it really convenient. The design is clever and saves space. It was definitely a missing link in my gadgetry collection and I’m getting a lot of use out of it.

It’s a clever device and perfect for a jetsetter, business or leisure traveler, digital nomad, jetsetter, life in a small space, or just anyone who likes to save space and weight. It’s fun for efficiency-and-multitasking geeks. It’s ideal for work from home, as well asin a coffee shop, plane, bus, train, or coworking space–your seatmates/tablemates will love you for not hogging the outlets. You could even offer to charge their stuff.

Here in the US, we use both 2-pin and 3-pin plugs, which are for grounding or earthing to protect devices from electrical shock. Luckily, this travel adapter lets you plug in a 2- or 3-pin plug. I had to push fairly hard to get the plug in, but it works fine. Whatever effort that took is more than made up for in not having to carry so many power bricks. 

As usual, it took almost overnight to charge my iPad Pro as on US power (using the Apple charger it came with), which is 120V. In Europe and Australia, things run at a clip of 220-240V, while in high-tech Japan they go at only 110V. Adapters don’t convert voltage, so the adapter doesn’t affect charging speed. 

You can charge up to 5 devices at once, whether they are USB-C, USB, or AC. With the ability to use this in 150 countries, I can’t wait to start traveling again.
