Compare the plug shapes, voltage and frequency in Peru and Malawi, and find out which adapter you need before you travel.
Adapter required
Yes — coming from Peru, you will need a travel adapter for Malawi. Peru uses Type A/Type B/Type C plugs, and Malawi uses Type G, so the pin shapes will not fit any wall socket. 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.
Frequency differs (60 Hz vs 50 Hz). Rarely an issue for most electronics, but can affect motor-driven devices like clocks and shavers.
