Why Plug Standards Matter?
Travel Preparedness:
- Use adapters (e.g., Type C to Type G) for cross-region travel.
Product Compliance:
Exported devices must meet certifications (e.g., UL, CE, CCC).
Electrical Safety:
Mismatched voltage (e.g., 120V device in 230V outlet) risks damage.
Conclusion
Knowing plug standards prevents travel hassles and ensures product compliance. Opt for universal adapters or 100-240V compatible devices.
