Charging a Honda Prologue at Home

The Honda Prologue is built on GM's Ultium platform— essentially a Chevy Blazer EV sibling — and charges at home over a J1772 inlet at up to about 11.5 kW. So a 48-amp Level 2 charger lets it draw its full AC speed, with no adapter needed at home.

Because the Prologue shares GM underpinnings, its home charging behaves like the Equinox and Blazer EV: a standard J1772 charger, sized to the car's roughly 11.5 kW onboard limit. Confirm your trim and buy the amperage the car can actually use.

The connector: J1772 at home

The Prologue uses a J1772/CCS1inlet, so home charging is plain J1772 — any standard Level 2 unit works, no adapter. Honda has committed to NACS for future cars and provides a DC adapter for Tesla Supercharger access, but that is a road-trip accessory, not part of your home setup. A 2025+ car with a factory NACS port would instead pair with a NACS home charger or a J1772 unit plus a J1772-to-NACS adapter— check your inlet.

What amperage to buy

With an onboard charger near 11.5 kW, a 48-amp charger on a 60-amp circuit reaches the ceiling. A 40-amp unit like the Emporia Level 2 on a NEMA 14-50 outlet still fills the car overnight for normal driving. Size the circuit with the wire size and breaker guide.

On the road

For trips the Prologue uses the CCS network and Tesla Superchargers with Honda's NACS DC adapter. Our DC fast charging explainer and Equinox EV guide (its Ultium cousin) cover the details.
