2027 Mercedes-Benz EQS 550 4matic (SUV): home charging cost in Hawaii

A 2027 Mercedes-Benz EQS 550 4matic (SUV) draws 42 kWh per 100 miles per the EPA; at Hawaii's 45.95¢/kWh residential rate that's $19.3 per 100 miles charged at home, versus $16.02 for a 25.5-mpg gas car covering the same distance. This model costs more to charge at home than gas would here: 20.5% more than gas per mile here, not less — the arithmetic isn't clamped to always favor charging.

Annual cost, at 15 thousands miles a year

Driving 15,000 miles a year — fueleconomy.gov's own default assumption — a 2027 Mercedes-Benz EQS 550 4matic (SUV) charged at home in Hawaii costs about $2,895/year in electricity, against about $2,403/year for the gas-car comparison. That's about $492 MORE a year than the gas comparison, not less.

Cost of a full charge

Before you install a home charger in Hawaii

The numbers above assume Level 2 home charging is already in place — the electrical work behind that is a real, separate cost that varies by panel, wiring, and local labor rates, not something this page's per-mile math includes.
