Pourquoi les appareils plantent-ils, coupure de courant ou scintillement après avoir rallongé manuellement le cordon d'alimentation, et quelle est la bonne solution?

L'extension manuelle du cordon d'alimentation CC de l'adaptateur provoque une instabilité de l'alimentation et des interférences électromagnétiques., conduisant à des accidents de l'appareil, écrans noirs et scintillements. Below are the core risks and official solution.
Key Risks of Custom Power Cord Extension

1. Severe Voltage Drop (Core Issue)
   Longer cables increase resistance and cause voltage drop. Insufficient power results in system throttling, black screens and frequent crashes.
2. Overheating & Hidden Safety Risks
   Power loss turns into excess heat, causing cable overheating and accelerated aging. Severe cases may lead to short circuits and fire risks.
3. Increased Electromagnetic Interference
   Oversized cables pick up mains interference, causing keyboard/touchpad jitter, screen flickers, ripples and intermittent power disconnection.
4. Non-negotiable Wiring Specification
   Factory DC cables are precisely calibrated. Any self-extension will definitely cause voltage drop and violate official power specifications.
