The best home charger for a GMC Hummer EV
A very large electric truck and SUV with a CCS port. A J1772 home charger plugs straight in -- and the battery is big enough that the circuit size genuinely matters.

The connector
CarGurus lists the GMC Hummer EV in GM's EV lineup and reports that GM's existing EVs, apart from the 2026 Optiq twins, have a NACS adapter available for NACS fast chargers. Its own port is CCS, whose AC section is a J1772 inlet -- so any J1772 home charger connects directly.
| Your truck | Port | Buy |
|---|---|---|
| Hummer EV pickup or SUV | CCS (J1772 for AC) | A J1772 Level 2 charger |
How much the circuit matters
An illustrative 100 kWh refill -- your number will differ
At 32 A (7.7 kW): about 13 hours
At 40 A (9.6 kW): about 10 hours 25 minutes
At 48 A (11.5 kW): about 8 hours 40 minutes
At 50 A (12 kW): about 8 hours 20 minutes
A truck this size may regularly need more than a night at a smaller setting. Confirm the onboard charger's rate in the manual, then have the panel checked for a 60-70 A circuit. Load calculation.

The chargers in detail
Two high-output J1772 units and a dual-connector unit, each with the case against it.
1. Homes with an uncertain panel
ChargePoint Home Flex
ChargePoint · J1772 · 50 A / 12 kW · 23 ft cable
The most adjustable unit here. It can be set anywhere from 16 A to 50 A, which makes it the one to buy when you do not yet know what your panel will allow.
What is good
- Six selectable amperage settings from 16 A to 50 A
- Sold in both hardwired and NEMA 14-50 versions
- Rated for indoor or outdoor installation
- The app is mature and does not require a subscription
What is not
- 23 ft is a foot shorter than the longest cables in this group
- The 50 A setting needs a bigger circuit than most panels have spare
| Maximum output | 50 A / 12 kW at 240 V |
|---|---|
| Amperage settings | 16, 24, 32, 40, 48 or 50 A |
| Connector | SAE J1772 |
| Cable | 23 ft |
| Installation | Hardwired or NEMA 14-50 |
| Certification | UL listed, Energy Star |
| Warranty | 3 years |
Skip this if: Skip it if your circuit is already fixed and you just want the cheapest safe 40 A unit. You are paying for flexibility you will not use.

2. Long reach outdoors
Autel MaxiCharger AC Home
Autel Energy · J1772 · 50 A / 12 kW · 25 ft cable
The 25 ft cable is the longest in this group, and the NEMA 4 case plus a cold-flexible cord make it the easiest unit to live with on an exposed outside wall.
What is good
- 25 ft cable, the longest of the wall units here
- Sold in NEMA 14-50, NEMA 6-50 and hardwired versions
- NEMA Type 4 enclosure rated for rain, snow, hail and sleet
- Wi-Fi and Bluetooth, so it still works if the Wi-Fi drops
What is not
- The 50 A version is hardwired only
- The app has more features than a first-time owner needs
| Maximum output | 50 A / 12 kW hardwired; 40 A / 9.6 kW plug-in |
|---|---|
| Connector | SAE J1772 |
| Cable | 25 ft |
| Enclosure | NEMA Type 4 |
| Certification | Tested to UL standards by CSA |
| Warranty | 3 years |
Skip this if: Skip it if your parking spot is right next to the panel. You are paying for cable you will coil up and never use.

3. A two-car, two-connector garage
Tesla Universal Wall Connector
Tesla · J1772 + NACS · 48 A / 11.5 kW · 24 ft cable
The Wall Connector with a J1772 adapter built into the holster, so it charges a Tesla and a non-Tesla without anything loose to lose.
What is good
- Charges NACS and J1772 cars without a separate adapter to store
- Same 48 A output and four-year warranty as the Gen 3
- The adapter docks in the holster, so it cannot walk off
What is not
- Costs more than the NACS-only Gen 3
- Hardwired only
| Maximum output | 48 A / 11.5 kW at 240 V |
|---|---|
| Connector | NACS with an integrated J1772 adapter |
| Cable | 24 ft |
| Installation | Hardwired |
| Warranty | 4 years |
Skip this if: Skip it if both cars use the same connector. You are paying for an adapter you do not need.
