Will my UK appliances work?
The voltage is 120V, 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.
