Everything you need to know about travel adapters buying guide: plug types, voltage, and ports explained, explained plainly.
Type A/B (flat parallel pins, sometimes with a round ground pin): North America, Central America, Japan, and parts of South America.
Type C/E/F (two round pins): most of continental Europe, plus parts of Asia, South America, and Africa.
Type G (three rectangular pins): the UK, Ireland, Hong Kong, Singapore, and Malaysia.
Type I (angled flat pins): Australia, New Zealand, China, and parts of the Pacific.
Type D/M (larger round pins): India, South Africa, and parts of Africa.
This is the most consequential distinction in the category.
A plug adapter changes only the physical shape of the plug.
The electrical current passing through it is unchanged.
Nearly all phone, laptop, tablet, and camera chargers are dual voltage, meaning they list an input range like 100-240V on the brick itself, and only need a plug adapter to work anyw here in the world.
A voltage converter is a different product.
A standard USB-A port typically delivers up to 2.4A, adequate for charging a phone overnight but slow for tablets or larger devices.
A USB-C port with Power Delivery (PD) support, typically rated 18W or higher on travel adapters, charges PD-compatible phones and tablets meaningfully faster.
Check the specific wattage listed, not just whether a port is labeled USB-C, since a non-PD USB-C port charges no faster than USB-A.
Built-in fuse: protects against power surges damaging connected devices.
This should be present on every adapter, even budget models.
Safety shutters: block accidental contact with live pins when the adapter isn't in use.
An inexpensive feature that's a red flag when absent.
Surge protection: a more robust safeguard than a basic fuse, worth the modest price increase for expensive electronics on unfamiliar hotel wiring.

FAQ
Type A/B: North America, Central America, Japan, parts of South America. Type C/E/F: most of continental Europe, plus parts of Asia, South America, and Africa. Type G: UK, Ireland, Hong Kong, Singapore, Malaysia. Type I: Australia, New Zealand, China, parts of the Pacific. Type D/M: India, South Africa, parts of Africa. A universal adapter with interchangeable heads covers all of these in one device.
A travel adapter changes only the physical plug shape so it fits a foreign outlet. It does nothing to the electrical current. A voltage converter (or transformer) actually steps the incoming voltage up or down to match what a device needs. Most modern electronics are dual voltage and only need an adapter. Single-voltage appliances need a genuine converter, a heavier, bulkier, and more expensive product.
Only if the USB-C port supports Power Delivery (PD) at a meaningful wattage, typically 18W or higher, and your device supports receiving PD fast charging. A USB-C port without PD support charges no faster than a standard USB-A port. Check the specific wattage rating on the adapter's USB-C port, not just its presence, before assuming it will charge faster.
