Travel adapters, voltage and USB-C: what to buy
Two things get confused in adapter listings: the plug shape and the voltage. Getting the first wrong means it does not fit; getting the second wrong can mean smoke.
Plug types by region
- Type A/B — USA, Canada, Mexico, Japan
- Type C/F — most of Europe
- Type G — UK, Ireland, UAE, Singapore, Hong Kong
- Type I — Australia, New Zealand, China, Argentina
A universal adapter covers all of them, usually with a slider or a stack of clip-on plugs. Japan and the USA share a shape but not always a voltage.
Voltage is the real risk
- Phones, laptops, camera chargers are nearly all dual-voltage (100-240V) — a plug adapter is enough.
- Hair dryers, straighteners, kettles are often single-voltage. Plugging a 120V dryer into 230V destroys it, and sometimes the socket. Buy a dual-voltage travel dryer instead of a converter.
What to look for
- GaN USB-C charger, 45-65W: charges a laptop and two phones from one brick
- Retractable or folding pins so the adapter does not tear your bag's lining
- A 100-240V input rating printed on the device — always check before trusting it
- Surge protection if you are going somewhere with unstable mains
Cable discipline
One USB-C to USB-C cable, one USB-C to Lightning or micro-USB, plus a short multi-tip cable covers almost everything. Keep them in a flat pouch so they do not knot around your toiletry bag. Compare chargers and adapters in Travel adapters & tech.
