- Professional install for hardwired units: Tesla and electric code require a certified electrician.
- NACS vs. J1772: Tesla units use NACS; non‑Tesla units need the adapter.
- Smart vs. simple: Consider if you want scheduling, notifications, OTA updates.
- Location and durability: Outdoor exposure may require sturdy housing (like Grizzl‑E).
