- Material and durability: Industrial-grade housings, corrosion resistance, and robust terminals help with longevity in challenging environments.
- Installation compatibility: Check whether a wall plate is included, and verify box size, wire gauge compatibility, and whether a single- or multi-gang installation fits your space.
- Plug-in vs hardwired: Some devices are plug-in receptacles for convenience, while others are designed for direct hardwired connections; select based on your setup.
- Warranty and OEM support: Consider manufacturer warranties and readily available replacement parts for long-term maintenance.
- Noise and heat considerations: High-load use requires reliable contact integrity and materials that resist overheating during continuous charging.
