GMC Hummer EV SUV Home Charger Requirements by Trim
All 2 trims need the same thing at home: a 80A charger on a 100A circuit reaches full speed on every one.

Every Hummer EV SUV trim, side by side
From each trim's onboard charger rating, not a generic EV number. Pick your trim to run the assessment with it pre-selected.
| Trim | Years | Onboard charger | Draw at 240V | Full-speed install | Empty to full | Range per hour | Range / battery | Check |
|---|---|---|---|---|---|---|---|---|
| 2X | 2024–2026 | 19.2 kW | ~80A | 80A charger, 100A circuit | 8.9 hrs | ~34 mi | 303 mi / 170 kWh | Check panel |
| 3X | 2024–2026 | 19.2 kW | ~80A | 80A charger, 100A circuit | 10.7 hrs | ~29 mi | 314 mi / 205 kWh | Check panel |
Draw = onboard charger kW x 1000 / 240V. Empty to full = battery kWh / charger kW. Range per hour = charger kW x the trim's efficiency. DC fast peaks: 2X 350 kW, 3X 350 kW.
Range added per hour, by charger size
Miles added per hour of charging at common home charger settings. Past a trim's onboard rating a bigger charger adds nothing, so those cells are marked.
| Charger | 2X | 3X |
|---|---|---|
| 16A (3.8 kW) | ~7 mi | ~6 mi |
| 24A (5.8 kW) | ~10 mi | ~9 mi |
| 32A (7.7 kW) | ~14 mi | ~12 mi |
| 40A (9.6 kW) | ~17 mi | ~15 mi |
| 48A (11.5 kW) | ~20 mi | ~18 mi |
| 8-hour overnight, full speed | ~272 mi | ~232 mi |
What this means for your panel
The circuit in the table is what lets your trim charge at its full rating. A smaller circuit still works and charges slower. Whether your panel has room for the circuit you want depends on everything else already on it: that is 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.
GMC Hummer EV SUV charging questions
What size circuit does a GMC Hummer EV SUV need for home charging?
Every Hummer EV SUV trim reaches its full home charging speed with a 80A charger on a 100A circuit. Whether your panel has room for that circuit depends on everything else already on it.
How many amps does a GMC Hummer EV SUV draw on Level 2?
80A at 240V, depending on trim. That is the onboard charger rating (19.2 kW) divided by 240 volts.
How long does a GMC Hummer EV SUV take to charge at home?
About 8.9 to 10.7 hours from empty to full at each trim's maximum Level 2 speed: battery size divided by onboard charger rating. Most nights you only refill what you drove.
Do all Hummer EV SUV trims charge at the same speed at home?
For 2026 models, yes: every Hummer EV SUV trim listed here uses a 19.2 kW onboard charger, so the home install is the same.
