Can I safely charge my iPhone in a UK plug adapter without a voltage converter?

Im traveling to the UK and bought a plug adapter. It warns that it does not convert voltage. Can I safely charge my iphone in the usb-c port on it, or do I need to use an iphone brick as well?

Thanks!

Although virtually any "brick" is 100-240V compatible, if you really want to be 100% sure, it would help if you could provide the make and model number of your "brick".


Then, we can log on to the "brick" manufacturer's site to get all of the specifications.......something that you can do easily as well. If the power requirements state 100-240 Volts.....as they very likely will....you are all set.


If the "brick" that you are referring to is an Apple device, no need to look any further. You can be 100% sure that it will operate worldwide without needing a voltage converter.

can I plug into the usb-c?


What device.....make and manufacturer.....are you calling "the usb-c".


Most "plug adapters" are simply that......adapters.....not power supplies. Examples of adapters are pictured below.




Are you saying that the "plug adapter" that you purchased to convert the Standard U.S. plug to the U.K. plug also has a built-in USB-C port (or ports)?
