Plug types used in United Kingdom

Type G Reference shape and compatible sockets

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?

A voltage converter is unnecessary only if your charger’s actual INPUT range covers the local supply and frequency, and its manufacturer permits this use. Confirm the exact outlet, plug fit and any required grounding. A typical charger profile does not verify your model.

Is 230⁠V dangerous for US devices?

Do not connect a mismatched single-voltage appliance directly. For high-power heating appliances use a local-voltage model, not a travel converter workaround. Confirm the actual input label, frequency and grounding even for a 100-240V charger.

What plug type does United Kingdom use?

United Kingdom uses Type G sockets at 230⁠V / 50⁠Hz.
