Compare the plug shapes, voltage and frequency in Costa Rica and Saudi Arabia, and find out which adapter you need before you travel.
Adapter required
Yes — coming from Costa Rica, you will need a travel adapter for Saudi Arabia. Costa Rica uses Type A/Type B plugs, and Saudi Arabia uses Type G, so the pin shapes will not fit any wall socket. Voltages differ (120 V at home vs 230 V abroad), so check the label on each device. Most modern dual-voltage chargers handle the swing without a converter, but heating appliances usually do not.
