2026 Fiat 500e: home charging cost in Hawaii

In Hawaii, home electricity runs 45.95¢/kWh — put a 2026 Fiat 500e's EPA-rated 29.2 kWh/100mi against that and 100 miles costs $13.41, versus $16.02 for a gas car averaging 25.5 mpg. Charging at home is cheaper than gas here: 16.3% less than gas per mile, here specifically.

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.

Ask a licensed Hawaii electrician to quote the install before this math becomes a real decision.
