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?

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.

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.
