Helpful NY Times article on overseas electrical current, adapters, plugs
I’m headed for the England/Scotland/Wales trip at the end of August and voila! Here comes this highly informative article on travel voltage converters, adapters, and just about everyone else one needs to know about plugs overseas. (Think I’ll leave my hair dryer at home…I don’t want it blowing up in my face, as this article warns!)

One of the better articles on this issue I've read. Useful without feeling you needed an electrical engineering degree to understand.
I have the device shown as their top pick, and it works well.
I have that adapter device, also. Agree it works well. It is larger than a dedicated adapter but it also includes USB outlets. It will adapt to most outlets in the world.
Oops, I have a different one that I think is better. The one they recommend only has one USB-C outlet and four USB-A outlets. The one I have has three USB-C outlets and two USB-A outlets. Here's a link to it on Amazon - https://www.amazon.com/dp/B0CBF376VD
I also have one that is higher power and has four USB-C outlets (two of which are PD compatible) and one USB-A. Max power is 100 watts. But more expensive. https://www.amazon.com//dp/B0D66D966R/
Just took a closer look. The one I have is Epicka TA-205. It has 3 USB-A and 2 USB-C including one PD compatible (fast charge) USB-C port. I chose this one to balance weight with capability/charging speed. This one is rated at 35W DC output. You can get higher power units, but then it gets heavier.
Just so you know and without getting too technical, don't expect all the USB-A ports to put out 2.4 amps and USB-C ports to put out 3.0 amps at the same time. The total capacity of that device is only 6.0 amps total which is shared amongst all the USB ports.
For instance if you plug in 3 devices that are compatible with fast charging, high 3 amp USB-C power (or higher with USB Power Delivery (PD)) each port will only supply 2 amps and the devices will not charge as fast as you might expect. This is one argument for devices capable of fast charging, having their own power module.
Here's the one I use. Very straightforward: https://checkplug.com
That looks like a good site. Thanks for posting.
Alan S - Don't forget PD (fast) USB-C charging increases the voltage up to 20V (and more recently 48V for higher power devices), so the current demand is cut 4x compared with 5V USB slow charging.
BKMD - Don't forget that the charger is rated at a certain wattage. Even if you increase the voltage, the wattage still shouldn't be exceeded. To get more out of a device, you need to purchase one rated at a higher wattage.
Alan's point that high demand devices, such as a computer, should be charged on a dedicated charger is well taken.
Mike - Valid point. I interpreted Alan's post to mean that a device could only charge at 15W max (5V @3A), which isn't the case. But yes, the overall power rating is still a limiting factor.
Besides that little cube, I always bring my laptop's charger which is USB-C and rated at 65W, which can be plugged into the US-style port on the charging cube, as pass-through for the US plugs is rated at 1000-1200W.
I think we've now beaten this to death
Our essential is a travel extension cord
Yup!
