Using US Electronics in the United Kingdom
You will need a Type G plug adapter to fit American Type A/B plugs into British three-pronged sockets. Furthermore, because the UK operates on 230V (compared to 120V in the US), single-voltage heating appliances like curling irons and hair dryers will require a step-down voltage converter.

Key Electrical Gotchas in United Kingdom
British sockets feature an internal mechanical shutter for child safety. The longer earth pin of a Type G plug physically opens the live and neutral shutters. Some cheap adapters get stuck if their earth pin is undersized.
UK bathrooms do NOT have standard 230V wall sockets. Under British building regulations (BS 7671), only special 115V/230V low-amperage two-pin shaver sockets are legally permitted near sinks.
Most British sockets include an individual on/off rocker switch next to the plug holes. If your device isn't charging, check that the switch is flipped on.
Device Category Breakdown
Smartphones, Tablets & Laptops
Safe with a simple plug adapter. Look for 'INPUT: 100-240V ~ 50/60Hz' printed on your charger brick.
Hair Dryers, Straighteners & Heated Tools
Requires caution. High-wattage hair dryers and flat irons rated solely for 120V will overheat or blow a fuse on the UK's 230V grid. Bring a dual-voltage model instead of a bulky converter.
Shavers & Personal Grooming
Compatible with UK bathroom shaver outlets or dual-voltage travel chargers.
