Hawaii uses standard United States currency (USD). Money changing services can be found at major shopping centres, hotels, at the airport & banks. Cash machines (ATMs) are also available all over the islands, at banks, hotels and convenience stores. However, on top of the differences in currency exchange, you may also have to pay a surcharge for withdrawing your money in such ATMs.

Most locations in Hawaii accept major international credit cards, including American Express, MasterCard and Visa. If you're traveling from a foreign country, it is advisable to activate the magnetic strip of your credit card for overseas use. Conversely, you can also call your credit card companies in advance to let them know you will be travelling abroad. This way they won’t question charges that start appearing from an international venue.


Tipping is a customary in the USA and generally, a 15-20% gratuity is standard for restaurants. It is also a customary to tip taxi drivers (around 15% of your taxi fare). Baggage porters, bellboys and valet parking attendants will also appreciate a tip of $1-2 whenever they help you with your bags/cars.

Electricity and Voltage

Electric power is standardized in all states across the USA at 110 Volts. Type A (flat blade attachment) and Type B (two flat parallel pins and a round grounding pin) electrical sockets are used. Therefore, if you are bringing any electrical appliance to the USA, you may need an adaptor to fit the US electrical receptacle. You may also need a converter to change the voltage from 110 volts to 220 volts.

Type A   Type B


International calls can be made directly from hotel rooms with IDD phones. 011 is the international prefix used to dial somewhere outside of USA, plus country code, area/city code and number. In some countries, some cell phone providers have an international calling plan. As such, you can also try to contact your cell phone providers in advance to activate an international calling plan which can potentially be less expensive.

Local Prepaid SIM Cards are readily sold around Hawaii; from major grocery stores like Walmart to local telco providers like AT&T, Verizon, etc.
