If you park in the garage, mount the charger inside. It is protected from weather, sun and theft, the cable stays clean and the wiring run from an attached-garage panel is often short. Mount it outside if you park on the driveway, if several cars or visitors need access, or if the garage is used for storage. Outdoor chargers must be outdoor-rated, and outdoor outlets need weatherproof in-use covers.
Comparison
| Inside garage | Outside | |
|---|---|---|
| Weather and UV | Protected | Needs IP54+/NEMA 3R+ rating |
| Theft and tampering | Low risk | Use locks or access control |
| Access for driveway parking | Cable may not reach | Easy |
| Wiring cost | Often lower | May need exterior conduit or trenching |
| Cold-weather charging | Warmer battery and cable | Cable stiffer in cold |
A Middle Option
Mount inside near the garage door with a long enough cable to reach a car parked just outside. Check the door can close without pinching the cable.
