🔌 Plugs
Yes. You'll need a US-style (type A/B) adapter. 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.
🕒 Time
Hawaii is 10 hours behind the UK in the UK winter and 11 hours behind the UK in the UK summer (the clocks change on different dates).
💶 Money
Hawaii uses the US dollar (USD). Tipping is expected: 18–20% in restaurants, $1–2 a drink in bars, 15–20% for taxis and hairdressers. Prices usually exclude sales tax too.
