40 amp vs 48 amp charger for a Chevrolet Equinox EV
For the trims below, EPA data shows the car accepts more than a 40 A charger delivers (9.6 kW). A 48 A charger (11.52 kW) saves up to about 1.8 hours on an empty-to-full charge (estimate). It needs a 60 A breaker instead of 50 A.
Per trim
| Trim | Empty→full at 40 A | Empty→full at 48 A | Miles per 8 h at 40 A | Miles per 8 h at 48 A | Why we think it accepts more |
|---|---|---|---|---|---|
| 2027 Equinox EV FWD | 10.3 h | 8.6–9.5 h | 247 mi | 296 mi (max) | EPA 240 V time implies an average of 10.4 kW, so it must accept more than 9.6 kW at times |
| 2027 Equinox EV AWD | 10.4 h | 8.7–9.5 h | 236 mi | 283 mi (max) | EPA 240 V time implies an average of 10.5 kW, so it must accept more than 9.6 kW at times |
| 2026 Equinox EV AWD (11 kW Charger) | 10.4 h | 9.1 h | 236 mi | 270 mi | EPA trim name states a 11 kW onboard charger |
| 2026 Equinox EV AWD (19 kW Charger) | 10.5 h | 8.8 h | 219 mi | 263 mi | EPA trim name states a 19 kW onboard charger |
Estimates: energy for the full EPA range (kWh/100 mi × range ÷ 100, at the wall) ÷ charging power. Where EPA states the onboard charger we cap at it. Otherwise the 48 A figure is a range: from full 11.52 kW down to the average power implied by EPA's 240 V time, because the true onboard limit isn't in EPA data. Real charging tapers near 100%.

Does it matter day to day?
Most drivers plug in overnight and rarely charge from empty. Both chargers add 247+ miles in 8 hours for the most efficient qualifying trim. The 48 A option mainly helps with long daily drives, short charging windows on time-of-use plans, or sharing one charger between two cars. The bigger circuit can cost more to install (wire size, panel capacity), and that cost isn't in our data.
