🇺🇸 What plug does United States use?
Type A/B sockets at 120V, 60Hz. The US uses Type A/B plugs at 120V/60Hz. Travelers from 230V countries like the UK or most of Europe need a Type A/B adapter and should check their device label for 100–240V support.| Travelling from | Adapter needed? | Voltage |
|---|---|---|
| The US | No | voltage is compatible — most modern electronics handle it fine |
| The UK | Yes | voltage differs — check your device for 100–240V dual-voltage support before assuming you can skip a converter |
| Canada | No | voltage is compatible — most modern electronics handle it fine |
| Australia | Yes | voltage differs — check your device for 100–240V dual-voltage support before assuming you can skip a converter |
| Continental Europe | Yes | voltage differs — check your device for 100–240V dual-voltage support before assuming you can skip a converter |
The US uses Type A and B interchangeably — B simply adds a grounding pin, and virtually every modern device and socket accepts either. The same standard is shared with Canada, so cross-border travel between the two needs no adapter at all.

What if I forget my adapter?
Adapters are widely sold at United States airports, electronics shops, and convenience stores near hotels and tourist areas — usually at a small markup over what you'd pay at home. If you're stuck, ask at your hotel front desk; many keep a few spares to lend.
