2026 Rivian R1T Dual Max (22in): home charging cost in Hawaii

In Hawaii, home electricity runs 45.95¢/kWh — put a 2026 Rivian R1T Dual Max (22in)'s EPA-rated 38.8 kWh/100mi against that and 100 miles costs $17.85, versus $16.02 for a gas car averaging 25.5 mpg. This model costs more to charge at home than gas would here: 11.4% more than gas per mile here, not less — the arithmetic isn't clamped to always favor charging.

2026 Rivian R1T Dual Max (22in): yearly cost in Hawaii

Driving 15,000 miles a year — fueleconomy.gov's own default assumption — a 2026 Rivian R1T Dual Max (22in) charged at home in Hawaii costs about $2,677/year in electricity, against about $2,403/year for the gas-car comparison. That's about $274 MORE a year than the gas comparison, not less.

What one full charge costs

A 2026 Rivian R1T Dual Max (22in) needs roughly 163.1 kWh to reach its EPA-rated 420-mile range, which runs about $74.96 at 45.95¢/kWh in Hawaii.

Next step: home charger installation

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.

Where these figures come from

The methodology guide names the exact EIA and EPA tables behind this page's numbers. This is one of the combinations where charging costs more than gas — the guide to when that happens explains why the arithmetic can go either way.
