We earn a commission when you buy through our Amazon links, at no extra cost to you. It never affects our rankings, and we say so when the cheaper product is the better buy. How this works.

The Honda Prologue is built on GM's Ultium platform (a cousin of the Chevy Blazer EV), and it charges like one: up to 11.5 kW (48 amps) at home on its ~85 kWh battery. A 48-amp Level 2 charger is the fastest useful option.

How long it takes and what it costs

At 48 amps the Prologue does 10 to 80 percent in about 5.5 hours - an overnight charge that adds roughly 28 miles of range per hour. That top-up costs about $10 at the US average rate.

Cost-to-charge calculator

Put in your electricity rate, your battery size and your car's efficiency. The math is the same one shown above, with a 10% charging loss included so the number is realistic.

A 10% to 80% charge
$11.56
A full (empty to 100%) charge
$0.05
Cost per mile
$5.08
Cost per 100 miles

Estimate only. Actual cost depends on your exact utility rate (including any time-of-use pricing and fees), your car's real efficiency, temperature, and charging losses. Check your electric bill for your true rate.

Connector and charger

The Prologue uses a J1772 port, so any Level 2 charger fits - a 48-amp unit gives full speed. Add a NACS-to-J1772 adapter to use Tesla-style chargers.
