Guatemala to Tonga: Complete Plug & Adapter Guide (2026) Adapter Needed

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

The plug types are different between these two countries. In Guatemala, outlets accept Type A/B, but in Tonga you'll find Type I sockets. A travel plug adapter is essential for this trip.

Voltage is another key difference. Guatemala uses 120V while Tonga uses 240V. 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.
