Typical full-speed install
80A charger on a 100A circuit
Reaches this car's 19.2 kW ceiling. Whether your panel has room for that circuit depends on everything else already on it - that's the actual assessment.
Connector
NACS
NACS (North American Charging Standard, originally Tesla's plug) is now the connector most new EVs are shipping with for both home Level 2 and public DC fast charging.
On the Celestiq Hand-Built specifically, that connector carries up to 19.2 kW at home on Level 2 and up to 200 kW on public DC fast hardware.
Charging speed by circuit size
None of these common home circuit sizes reach this car's 19.2 kW onboard ceiling - it can use every amp up to 48A.
| Charger setting | This car actually draws | Range added / hour | 8-hr overnight |
|---|---|---|---|
| 16A | 3.8 kW | ~10 mi | ~80 mi |
| 24A | 5.8 kW | ~16 mi | ~128 mi |
| 32A | 7.7 kW | ~21 mi | ~168 mi |
| 40A | 9.6 kW | ~26 mi | ~208 mi |
| 48A | 11.5 kW | ~31 mi | ~248 mi |
Overnight, at full onboard speed
416 mi / 8 hrs
520 mi across a 10-hour window, at 19.2 kW.
Approximate cost to fill from empty
$14.43
Assumes $0.13/kWh (a national-average estimate, not your local rate) × 111 kWh - about $0.048/mile.

Times scale with amperage - see the circuit-size table above for other settings.
What amperage does a Cadillac Celestiq draw on Level 2?
At its full 19.2 kW rate, the Cadillac Celestiq draws about 80A at 240V (kW × 1000 ÷ 240 = amps).
Can a Cadillac Celestiq use a 48-amp charger?
Yes, and it'll use the full 48A. A 48A charger delivers ~11.5 kW, which is at or under this car's 19.2 kW ceiling - about 31 mi of range per hour.
How much range does a Cadillac Celestiq add per hour on a Level 2 charger?
About 52 miles of range per hour at its 19.2 kW ceiling (19.2 kW × 2.73 mi/kWh efficiency).
How much range does an 8-hour overnight charge add to a Cadillac Celestiq?
Roughly 416 miles from an 8-hour overnight charge (52 mi/hr × 8 hours), or about 520 miles across a 10-hour window.
What's the DC fast charging ceiling for a Cadillac Celestiq?
Up to 200 kW on a public DC fast charger - well above its 19.2 kW Level 2 (home) ceiling, though DC fast rates taper as the battery fills.
