What EV Charger Do You Need for a 2025 GMC Hummer EV Pickup?
Many owners buy a standard forty-eight amp home charger and waste money on slow speeds because this pickup accepts up to eighty amps. You need an eighty amp Level 2 charger to fill the massive battery in ten point six hours. Plug into a standard household outlet and you will wait one hundred forty-one hours for a full charge.

Why 80 amps and not more
Your vehicle features a huge two hundred three point two kilowatt hour battery pack that demands heavy power delivery. A lesser forty or fifty amp unit throttles your input and stretches recovery times across multiple days. The onboard charger handles nineteen point two kilowatts at eighty amps, which translates to thirty miles of range per hour. Feeding it anything smaller leaves available charging speed on the garage floor.
What the install involves
This truck requires a hardwired setup because standard wall plugs cannot handle the load. Your electrician must pull a heavy-gauge circuit and land a one hundred amp breaker in the service panel. Verify your main electrical panel has spare capacity for this massive draw before buying any hardware. Hardwiring eliminates plug degradation and remains the only safe way to deliver this level of current.

The first unit matches your car's full 80 A. The others are slightly slower but cost less.
One of the few home units that can feed an 80 A car. Needs a 100 A circuit.
Adjustable from 16 A to 50 A in the app, which helps if your panel is tight.
Energy monitoring built in. Hardwire it for the full 48 A.

Common questions
- What connector does this truck use?
- It uses a J1772 connector. This model year falls in the industry transition period, so many vehicles ship with a NACS port but include a J1772 adapter. Confirm your specific port before buying.
- Can I use a normal wall outlet?
- You can plug into a standard household outlet for Level 1 charging, but it adds only two point three miles of range per hour. A full charge takes one hundred forty-one hours this way.
- Why does the EPA charge time differ from the peak rate?
- The EPA test estimates eleven point two hours and twenty-eight miles per hour because standard testing protocols do not always run at the car's absolute peak AC rate. Your actual garage experience will match the ten point six hour full charge time when using the maximum eighty amp hardware.
- Do I need an electrician for the install?
- Yes. You need a professional to pull the one hundred amp circuit and land it on the correct breaker in your panel.
