Travel adapter from Guatemala to Nepal
Adapter Required
Yes — coming from Guatemala, you will need a travel adapter for Nepal. Guatemala uses Type A/Type B plugs, and Nepal uses Type C/Type D/Type M, 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. The mains frequency is also different (60 Hz vs 50 Hz). This rarely matters for electronics but can affect motor-driven devices like clocks and shavers.
