Short answer: The 2026 Cadillac Celestiq charges via the NACS (Tesla-style) port. At home, a Level 2 charger (240V, 11.5 kW) fills the 111 kWh battery in 13 hours. On a 200 kW DC fast charger, 10→80% takes 24 minutes. Native Tesla Supercharger access — no adapter needed. Home charger installation averages $1,200 with a 30% federal tax credit up to $1,000 available through 2032.
| Charger Type | Power | Time 0→100% | Time 10→80% | Where |
|---|---|---|---|---|
| Level 1 (120V) | ~1.4 kW | ~80 hr | ~56 hr | Standard wall outlet (impractical) |
| Level 2 (240V, low) | 7.2 kW | ~16 hr | ~11 hr | Older home installations |
| Level 2 (240V, max) | 11.5 kW | 13 hr | 9 hr | Recommended home setup |
| DC Fast (Tesla V3 SC) | 150 kW | ~50 min | ~30 min | Tesla Supercharger V3 |
| DC Fast (max) | 200 kW | ~35 min | ~24 min | Tesla V4, Electrify America 350kW (capped) |
The Cadillac Celestiq is one of the first GM vehicles to ship with a native NACS (North American Charging Standard) port instead of CCS. Practical implications:
