🔌 Plugs
Yes. You'll need a universal travel adapter. The voltage is 127/220V, much lower than the UK's 230V. Phone, laptop and camera chargers marked "100–240V" are fine with an adapter. UK hairdryers, straighteners and kettles usually won't work properly unless they're dual-voltage. You'd need a voltage converter, or buy one locally.
