- Security Level: For high-safety needs, prefer models with a security screw and key system, often made from fire-resistant ABS or metal. Consider whether you need a key-retaining feature to avoid losing keys during use.
- Installation Effort: Some models require no tools, while others demand screws or security screws. Assess your comfort level with basic hardware installation.
- Environment: If outdoor use is necessary, choose weatherproof or weather-resistant housings and materials designed to withstand elements.
- Space For Large Plugs: If you frequently use large adapters or bulky chargers, prefer deeper interiors or boxes with extra space to avoid crowding.
