Hawaii home charging cost for the 2026 Porsche Taycan 4 Perf Battery Plus

In Hawaii, home electricity runs 45.95¢/kWh — put a 2026 Porsche Taycan 4 Perf Battery Plus's EPA-rated 38.7 kWh/100mi against that and 100 miles costs $17.8, versus $16.02 for a gas car averaging 25.5 mpg. This model costs more to charge at home than gas would here: 11.1% more than gas per mile here, not less — the arithmetic isn't clamped to always favor charging.

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.

Where these figures come from

Every figure on this page traces to a named EIA or EPA dataset — see the methodology guide. 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.
