Do I need a voltage converter if I have an Apple power adapter?

I’m from the US and traveling to the UK. I know the voltage is different in the two countries and have an outlet adapter but not a voltage converter. I read that Apple power adapters can serve as voltage converters. Is this true? If so do they work with non-Apple devices (such as Snapchat Spectacles and a Fitbit) as well?

Sorry for the confusion. I was referring to the Apple charger boxes that come with all Apple devices, not the traveler kit. Do you know if this works for other non-Apple devices as well?

The Apple plug adapter -- Apple World Travel Adapter Kit - Apple

does not serve as a voltage converter. However with Apple devices a voltage converter is not needed for the UK as the devices themselves are designed for a range of voltages. The 5W charger for my iPhone XS for example states in the very fine print by the plug prongs that it is for 100 to 240 volts.

For all intents and purposes, the charger has no idea of what device is attached.


The USB-A charger shipped with iPhones takes any input voltage between 100 and 240V and outputs the standard 5V charge used by any USB device (whether that's an iPhone, and Android phone, a game controller, set of headphones.. whatever - they all expect 5V DC).

Similarly, the USB-C charger shipped with current MacBooks will take any voltage input and charge *any* standard USB-C device, Apple or otherwise.
