Guyana to Dominican Republic: Complete Plug & Adapter Guide (2026) Adapter Needed

Traveling from Guyana to Dominican Republic means crossing into a different electrical system. Before you leave, take a moment to understand the plug types and voltage used in Dominican Republic so you can keep all your devices charged and ready.

Both Guyana and Dominican Republic use Type A/B plugs, so your devices should plug right in. An adapter isn't strictly necessary for this trip.

Voltage is another key difference. Guyana uses 240V while Dominican Republic uses 120V. If your device only supports one voltage, using it with the wrong supply could cause overheating or permanent damage. Look for "Input: 100-240V" on your charger. Most modern phone and laptop chargers support this range.

Most modern phone chargers, laptop adapters, and camera chargers are designed to handle 100-240V input, so they'll work anywhere with just a plug adapter. Heat-producing appliances like hair dryers and flat irons are often single-voltage, so check before you plug them in abroad.
