Quick Answer
The world uses 15 standard plug types (A-O). North America and Japan use 120V/60Hz with Type A/B plugs. Europe, Asia, and Africa use 220-240V/50Hz with Types C/E/F/G. Always check whether your device supports dual voltage (100-240V) before international travel.

Design Notes
Electrical plug standards are the result of over a century of independent national electrification programs. Harmonization efforts (e.g., IEC 60906-1 proposing a universal Type N plug) have had limited success. For product design targeting global markets, use IEC C14 inlets with detachable country-specific power cords.
Common Mistakes
- 1
Assuming a plug adapter also converts voltage — most adapters only change the physical shape, NOT the voltage.
- 2
Using devices rated for 120V only on a 240V supply without a transformer — this will destroy the device.
- 3
Forgetting that Japan uses 100V (not 110-120V like the US) which can cause some US devices to underperform.
Knowledge Base
Quel type de prise est utilisé en France ?
La France utilise le Type E (CEE 7/5) avec broche de terre mâle sur la prise murale. La tension est 230 V / 50 Hz. Les prises Type C (Europlug) non mises à la terre sont aussi compatibles.
Puis-je utiliser un appareil 60 Hz sur du 50 Hz ?
Charges résistives : aucun problème. Moteurs asynchrones : 17 % plus lents. Alimentations à découpage modernes (ordinateurs, chargeurs USB) : compatibles 50/60 Hz automatiquement. Vérifiez l'étiquette de l'appareil.
