Mercedes-Benz EQS home charger: charge time and which amps it can use
2024-2026 model years, 21 EPA-listed configurations
The Mercedes-Benz EQS accepts up to 9.6 kW of AC power from a home charger, which is 40 A at 240 volts (computed from the kW figure; the maker publishes kW only). Source: the maker's own documentation. On 240 volts a full charge takes about 31.1 to 35.4 h on a 16 A charger, 15.6 to 17.7 h on 32 A, 12.4 to 14.1 h on 40 A and 12.4 to 14.1 h on 48 A. It reaches that limit at 40 A, so a 48 A charger adds nothing on this car: it charges at the same 9.6 kW. J1772 charge port, the standard port. J1772 chargers plug in directly; NACS chargers work with an adapter.

Charge time by charger amps
A charger's amp rating sets its power on a 240 volt circuit; the car then takes the smaller of that and its own onboard limit. Each row is one standard charger rating.
| Charger rating | Power at 240 V | Rate on this car | Full charge | Against the row above | Tracked chargers at this rating that fit |
|---|---|---|---|---|---|
| 16 A | 3.84 kW | 3.84 kW | 31.1 to 35.4 h | Slowest standard rating | 9 |
| 32 A | 7.68 kW | 7.68 kW | 15.6 to 17.7 h | Adds 3.84 kW | 22 |
| 40 A | 9.6 kW | 9.6 kW | 12.4 to 14.1 h | Adds 1.92 kW | 53 |
| 48 A | 11.52 kW | 9.6 kW | 12.4 to 14.1 h | Adds nothing: car limit reached | 52 |
Power is amps times 240 volts. Full-charge times divide the EPA wall energy for a full charge (120 to 136 kWh), which already includes charging losses, by the rate the car accepts. The comparison column reads the car's limit. The last column counts chargers in this database rated at exactly that current that plug into this car directly.

Selection rule, in full: only chargers with a verified price appear; grouped by the charger's rated current; the 5 lowest verified prices in each group. Nothing here is an editorial pick.
Prices were verified at a named seller on October 5, 2026. Rate and full charge assume the 9.6 kW onboard charger.

Lowest standby draw
Each list is named for its metric and drawn from all 180 chargers that plug in directly, priced or not. Standby draw comes from ENERGY STAR test data and is published for 89 of them.
Vehicle figures come from EPA fuel-economy data (2024-2026); the maximum AC rate is verified against the manufacturer's own documentation. Charger specifications follow the same methodology as every page on this site.
What a full charge costs
Electricity is the whole running cost, and it is the number that varies most by where you live. A full 120 to 136 kWh at the Mercedes-Benz EQS, priced three ways:
| Rate | Cents per kWh | Full charge |
|---|---|---|
| Louisiana, the cheapest state | 12.72 | $15.20 to $17.27 |
| National average | 18.31 | $21.88 to $24.86 |
| Hawaii, the most expensive | 48.00 | $57.36 to $65.18 |
Rates are the EIA residential series, July 2026. Your own utility and any time-of-use plan decide the real figure.
The circuit this car needs
A home charger is a continuous load, so the National Electrical Code sizes both the breaker and the conductor at 125 percent of its draw. A charger matched to this car's 9.6 kW ceiling pulls 40 amps at 240 volts, which needs a 50 amp circuit rather than the 40 amp one the arithmetic alone suggests. That gap is where most installation quotes go wrong.
Of the 180 chargers that plug in directly here, 139 meet or beat the car's ceiling. Going above it changes nothing for this vehicle, though it leaves headroom for a future one that draws more.
Mercedes-Benz EQS home charging questions
- How long does it take to charge a Mercedes-Benz EQS at home?
- On 240 volts, from empty to full: about 31.1 to 35.4 h on a 16 amp charger, 15.6 to 17.7 h on 32 amps, 12.4 to 14.1 h on 40 amps and 12.4 to 14.1 h on 48 amps. The Mercedes-Benz EQS accepts up to 9.6 kW of AC, and a full charge draws 120 to 136 kWh from the wall, which already includes charging losses.
- What amp charger can a Mercedes-Benz EQS use?
- It reaches its 9.6 kW onboard limit at 40 A (240 volts). It reaches that limit at 40 A, so a 48 A charger adds nothing on this car: it charges at the same 9.6 kW. 139 of the 180 chargers that plug in directly in this database reach that rate.
- Does a 48 amp charger charge the Mercedes-Benz EQS faster than a 40 amp one?
- No. The Mercedes-Benz EQS is limited to 9.6 kW, which a 40 A charger already delivers, so both charge it at the same rate.
- Which connector does the Mercedes-Benz EQS use?
- J1772 charge port, the standard port. J1772 chargers plug in directly; NACS chargers work with an adapter.
- How much does it cost to charge a Mercedes-Benz EQS at home?
- About $21.88 to $24.86 for a full charge at the national average residential rate of 18.31 cents per kWh (EIA, July 2026). Your own rate decides the real figure, and it varies by more than a factor of four between states.
- How were these chargers chosen?
- Only chargers with a verified price appear; grouped by the charger's rated current; the 5 lowest verified prices in each group. Nothing here is an editorial pick. Nothing is ranked by commission and no charger is called best. Every figure is verified against a primary source or left blank.
