Mercedes-Benz EQB Charging Time
A 2025 Mercedes-Benz EQB takes about 8.3 hours to charge from empty to full on a 240-volt Level 2 charger, according to its EPA test, and 8.25 to 8.32 hours across the 2025 trims. On a standard 120-volt outlet it takes about 55 hours. A full charge puts about 79.3 kWh through the plug for 205 miles of range.
Mercedes-Benz EQB charging time by charger
Figures for the 2025 EQB 300 4matic. 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 | 33 hr 2 min | 2.3 days |
| Level 2, 240 V, 16 A | 3.8 kW | 12 hr 23 min | 20 hr 39 min |
| Level 2, 240 V, 24 A | 5.8 kW | 8 hr 16 min | 13 hr 46 min |
| Level 2, 240 V, 32 A | 7.7 kW | 6 hr 12 min | 10 hr 20 min |
| Level 2, 240 V, 40 A | 9.6 kW | 4 hr 57 min | 8 hr 16 min |
| Level 2, 240 V, 48 A | 11.5 kW | 4 hr 8 min* | 6 hr 53 min* |
* Only if the car's onboard charger accepts that much power. On its EPA test it charged at about 9.5 kW; if that is its limit, a faster wall charger won't shorten the 8.3-hour full charge.

Cost to charge a Mercedes-Benz EQB
A full charge from empty draws about 79.3 kWh from the wall. At 18 cents per kWh it costs about $14.27, and a 20% to 80% top-up about $8.56. The EPA rates the EQB 300 4matic at 38.7 kWh per 100 miles, which works out to 7 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 EQB 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 EQB. The EV charging curve guide explains why it slows.
