What charging actually costs here

Filling a Mercedes-Benz EQS from empty in Hawaii costs $69.91. The car draws 132.6 kWh from the wall for a full 390-mile charge, and Hawaii residential electricity averages 52.72¢ per kWh. That works out at $17.92 per 100 miles, or $0.18 a mile.

Hawaii is more expensive than average: 52.72¢ against a national mean of 19.42¢, which ranks it 51 of 51 for electricity price. The same car costs $17.38 to fill in Nevada and $69.91 in Hawaii — a 4.0× spread across the country for identical driving.

This is one of the few places where the sum does not favour electricity. At 52.72¢ per kWh, running the Mercedes-Benz EQS costs $17.92 per 100 miles while a 30 mpg petrol car costs $13.62 — so over 12,000 miles you would spend about $517 more on electricity. Home solar or an off-peak tariff changes that quickly, but the flat residential rate does not.

Frequently asked questions

How much does it cost to charge a Mercedes-Benz EQS in Hawaii?

$69.91 for a full charge from empty. The car needs 132.6 kWh at the wall and Hawaii residential electricity averages 52.72¢ per kWh.

How much does a Mercedes-Benz EQS cost per mile in Hawaii?

About $0.18 a mile, or $17.92 per 100 miles. Over 12,000 miles a year that is roughly $2,151 of electricity.

Is charging a Mercedes-Benz EQS cheaper than petrol in Hawaii?

Not at the flat residential rate. Electricity costs $17.92 per 100 miles here against $13.62 for a 30 mpg petrol car, so you would spend roughly $517 more a year. Hawaii has the kind of electricity prices where an off-peak tariff or solar makes the difference.

How long does a full charge last?

The EPA rates the Mercedes-Benz EQS at 390 miles combined. Cold weather, motorway speeds and a loaded car all reduce that; the EPA number is a standardised test, not a guarantee.

Does this include charging losses?

Yes. The EPA's 34 kWh/100 mi figure is measured at the wall socket, so the energy lost in the charger and cabling is already in the number. No extra efficiency factor is applied.
