There isn’t enough information to report a personal charge time for the 2024 GMC Hummer EV: the charger’s output, starting and ending charge levels, and session duration are not established. GMC says the Pickup can accept up to 19.2 kW of Level 2 AC power under specific installation conditions, but that capability alone does not determine how long a particular home charging session takes.
What GMC publishes about 2024 Hummer EV home charging
For the 2024 Hummer EV Pickup, GMC lists a 19.2 kW-capable onboard charging module and a maximum home Level 2 charging rate of up to 19.2 kW. GMC says that maximum requires a dedicated 19.2 kW/100 A charging station installed by a professional. A vehicle’s maximum capability is not the output every home charger or circuit will provide. GMC’s 2024 Hummer EV Pickup configuration page describes the vehicle and installation requirement.
GMC estimates that a 19.2 kW Level 2 station can add up to approximately 30 miles of range per hour for the 2024 Hummer EV 2X and 3X Pickup. This is a manufacturer range-added estimate, not a fixed percentage of battery charge per hour or a promise of session duration. The GMC EV charging page gives the model-specific estimate; the 2024 GMC Hummer EV Pickup brochure similarly lists nearly 30 miles in an hour for the 2X Pickup.
Why the charger rating does not give an exact elapsed time
Actual charging speed depends on more than the charger’s nameplate output. GMC identifies battery condition, charging-station output, vehicle settings, and temperature as factors. GM’s 2024 operating information also notes that charge level affects timing and that charging slows as the battery recharges. Consequently, a quoted miles-per-hour estimate cannot be converted into a reliable start-to-finish time without knowing the session’s conditions and endpoints. GMC’s brochure and GM’s 2024 owner information provide those caveats.

How different home Level 2 outputs compare
| Charging setup | Published output or capability | What it means |
|---|---|---|
| Hummer EV Pickup onboard maximum | Up to 19.2 kW; GMC specifies a dedicated 19.2 kW/100 A station and professional installation to reach the maximum. GMC | Vehicle capability, not a guarantee that a home circuit or station supplies this rate. |
| GMC’s model-specific range-added estimate | Up to approximately 30 miles per hour on a 19.2 kW Level 2 station for the 2024 2X/3X Pickup. GMC | Estimated range added, not a measured battery percentage or full-session time. |
| Portable GM Dual Level Charger, 240 V mode | Up to 7.7 kW; listed for the 2024 Hummer EV Pickup. GM Genuine Parts | A lower-output option than the vehicle’s cited 19.2 kW maximum. |
| 11.5 kW Level 2 station | 11.5 kW tier shown in GMC’s charging guidance. GMC | Another available station output; the rating alone does not establish a specific session duration. |
GM Energy also lists home Level 2 output options on its home products page. A station’s advertised output is only one part of the setup: circuit capacity, compatible equipment, and installation determine what can actually be delivered.
What a useful firsthand charge-time report needs
To state how long one 2024 Hummer EV took to charge on a home Level 2 setup, the report needs the session record rather than an estimate derived from the vehicle’s maximum rating. Record:

- Charger make/model and its actual output, plus the circuit amperage.
- Starting and ending battery charge percentages.
- Elapsed time from the session start to the stated endpoint.
- Relevant conditions, especially ambient or battery temperature and any vehicle charging settings.
Without those details, the accurate answer is that GMC publishes charging capability and range-added estimates, but the elapsed time for this particular home session is not established.
