Mercedes-Benz G-Class Charging Time
A 2027 Mercedes-Benz G-Class takes about 14 hours to charge from empty to full on a 240-volt Level 2 charger, according to its EPA test. On a standard 120-volt outlet it takes about 83 hours. A full charge puts about 119 kWh through the plug for 249 miles of range.
Mercedes-Benz G-Class charging time by charger
Figures for the 2027 G 580 with EQ Technology. 20% to 80% is a typical daily top-up; 0% to 100% is a full charge from empty.
| Charger | Power | 20% to 80% | 0% to 100% |
|---|---|---|---|
| Level 1, 120 V outlet (12 A) | 1.4 kW | 2.1 days | 3.4 days |
| Level 2, 240 V, 16 A | 3.8 kW | 18 hr 36 min | 30 hr 59 min |
| Level 2, 240 V, 24 A | 5.8 kW | 12 hr 24 min | 20 hr 40 min |
| Level 2, 240 V, 32 A | 7.7 kW | 9 hr 18 min | 15 hr 30 min |
| Level 2, 240 V, 40 A | 9.6 kW | 7 hr 26 min* | 12 hr 24 min* |
| Level 2, 240 V, 48 A | 11.5 kW | 6 hr 12 min* | 10 hr 20 min* |
* Only if the car's onboard charger accepts that much power. On its EPA test it charged at about 8.5 kW; if that is its limit, a faster wall charger won't shorten the 14-hour full charge.

Cost to charge a Mercedes-Benz G-Class
A full charge from empty draws about 119 kWh from the wall. At 18 cents per kWh it costs about $21.42, and a 20% to 80% top-up about $12.85. The EPA rates the G 580 with EQ Technology at 47.8 kWh per 100 miles, which works out to 8.6 cents a mile. The US average home rate was 18.16 cents per kWh in August 2026 (EIA); the EV charging cost calculator takes your own rate.
Mercedes-Benz G-Class fast charging
DC fast charging bypasses the car's onboard charger and is far quicker, but the speed depends on each model's charging curve, which slows as the battery fills. That's why fast-charge times are quoted from 10% to 80%. The EPA doesn't test DC charging, so check Mercedes-Benz's quoted figure for the G-Class. The EV charging curve guide explains why it slows.
