Phone manufacturers consistently produce chargers in black and white due to several practical considerations, rather than mere design choice.

• The primary reasons include heat management, as these colours effectively dissipate heat, and production efficiency and cost, simplifying manufacturing processes for large quantities.
• Manufacturers like major phone companies opt for these colours to ensure safety, making damage like burn marks more visible during testing and use.
• Using standard black and white also streamlines the process of meeting safety standards, as the materials are already widely tested and certified, and simplifies user experience by avoiding complex matching to phone models.
