What home charger does the Mercedes-Benz G 580 with EQ Technology need?
| Model years | Trims | Charger | Breaker |
|---|---|---|---|
| 2025-2026 | all trims | 40 A | 50 A |
The Mercedes-Benz G 580 with EQ Technology accepts 9.6 kW on AC, so pair it with a 40 A charger on a 50 A breaker. That applies to the 2025 and 2026 models.
Why 40 amps and not more
The electric G-Class is heavy and square, so it uses a lot of energy per mile. Even at its full 40 A it adds only 18 miles of range per hour. A 32 A charger drops that to 14, and a charger above 40 A adds nothing, because the car will not draw past its own limit.
Charging time by model year
| Year | EPA range | Level 2, miles per hour | Level 2, empty to full | 120 V, miles per hour |
|---|---|---|---|---|
| 2026 | 239 mi | 18 | 13.4 h | 2.7 |
| 2025 | 239 mi | 18 | 13.4 h | 2.7 |
Level 2 figures assume a charger that supplies the car's full rate. Where a year shows a range, it spans that year's trims.
The 2025 and 2026 models are identical at the plug, with 239 miles of range and about 13.4 hours to fill from empty. Plugging in every night matters more with this vehicle than with most, since a long drive can take more than one night to put back.
What the install involves
A 40 A charger can plug into a NEMA 14-50 outlet on a 50 A breaker or be hardwired. Mount it where the cable reaches the charge port easily, since a large SUV leaves less room to maneuver in a garage.
- 40 A charger: 50 A breaker, NEMA 14-50 outlet.
- Charge port: J1772. From 2025 the industry is moving to the NACS port, and makers switch at different times. Some of these cars have a J1772 port and some have NACS with an adapter, so look at the port on your own car before choosing a charger's plug.

Common questions
- How long does a Mercedes-Benz G 580 take to charge overnight?
- About 13.4 hours from empty on a 40 A charger, so most owners top up nightly rather than charging from empty.
- Can a Mercedes-Benz G 580 use a NEMA 14-50 outlet?
- Yes. A 40 A plug-in charger on a 14-50 outlet with a 50 A breaker gives full speed.
- Would a 32 A charger work for a Mercedes-Benz G 580?
- It works on a 40 A breaker, but the rate falls from 18 to 14 miles of range per hour.
- How much does a 120 V outlet add to a Mercedes-Benz G 580?
- About 2.7 miles of range per hour, which is too slow to be useful.
