Plug types used in United Kingdom
Type G · grounded
Standard 230V at 50Hz. Type G is the large three-rectangular-pin fused plug, used nowhere on the European mainland. A US 120V single-voltage appliance plugged in here without a voltage converter will overheat and can catch fire — a plug adapter alone is NOT enough.

United Kingdom outlet FAQ
Can I charge my phone in United Kingdom without a converter?
Yes. Phone and laptop chargers are dual-voltage (100–240V) — you only need a plug adapter (Type G).
Is 230V dangerous for US devices?
Only for single-voltage (120V-only) devices like hair dryers — those need a voltage converter. Dual-voltage gear is fine on an adapter.
What plug type does United Kingdom use?
United Kingdom uses Type G sockets at 230V / 50Hz.
