Why plug types differ worldwide
Electrical systems were developed independently by each country. This is why plug shapes and voltage standards vary between locations.
Even if a plug fits, voltage differences can affect how your device works.
Plug adapters do not change voltage.
Most phone and laptop chargers support 100–240V and work worldwide—check your device label.

FAQ
- Do I need an adapter?
- If your country and the destination share at least one plug type, your plug may fit. Otherwise you need a travel adapter.
- When do I need a voltage converter?
- If the voltage difference is more than about 20%, some appliances (especially those without universal input) may need a converter or transformer.
- What about frequency (50 Hz vs 60 Hz)?
- Most modern chargers and electronics work on both. Motors and clocks can be affected; check your appliance label.
