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 Hummer EV Pickup 2X specifically, that connector carries up to 19.2 kW at home on Level 2 and up to 350 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 | ~7 mi | ~56 mi |
| 24A | 5.8 kW | ~11 mi | ~88 mi |
| 32A | 7.7 kW | ~14 mi | ~112 mi |
| 40A | 9.6 kW | ~18 mi | ~144 mi |
| 48A | 11.5 kW | ~21 mi | ~168 mi |
Overnight, at full onboard speed
288 mi / 8 hrs
360 mi across a 10-hour window, at 19.2 kW.
Approximate cost to fill from empty
$22.10
Assumes $0.13/kWh (a national-average estimate, not your local rate) × 170 kWh - about $0.070/mile.
