48 amp vs 80 amp charger for a Chevrolet Equinox EV
For the trims below, EPA data shows the car accepts more than a 48 A charger delivers (11.52 kW). A 80 A charger (19.2 kW) saves up to about 3.5 hours on an empty-to-full charge (estimate). It needs a 100 A breaker instead of 60 A.
Per trim
| Trim | Empty→full at 48 A | Empty→full at 80 A | Miles per 8 h at 48 A | Miles per 8 h at 80 A | Why we think it accepts more |
|---|---|---|---|---|---|
| 2026 Equinox EV AWD (19 kW Charger) | 8.8 h | 5.3 h | 263 mi | 433 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 80 A figure is a range: from full 19.2 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%. Vehicle data: fueleconomy.gov.
For the other 3 trim(s) EPA data doesn't show more than 11.52 kW being accepted, so an 80 A charger may not help them: 2027 Equinox EV FWD, 2027 Equinox EV AWD, 2026 Equinox EV AWD (11 kW Charger).
Does it matter day to day?
Most drivers plug in overnight and rarely charge from empty. Both chargers add 263+ miles in 8 hours for the most efficient qualifying trim. The 80 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.
