Compare the plug shapes, voltage and frequency in Nepal and Suriname, and find out which adapter you need before you travel.
Adapter required
Yes — coming from Nepal, you will need a travel adapter for Suriname. Nepal uses Type C/Type D/Type M plugs, and Suriname uses Type A/Type B, so the pin shapes will not fit any wall socket. Voltages differ (230 V at home vs 110 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 (50 Hz vs 60 Hz). This rarely matters for electronics but can affect motor-driven devices like clocks and shavers.
