Cadillac Optiq home charger: charge time and which amps it can use
2026 model year, 6 EPA-listed configurations
The Cadillac Optiq accepts up to 19.2 kW of AC power from a home charger on its highest-rated trim, which is 80 A at 240 volts (computed from the kW figure; the maker publishes kW only). Source: the maker's own documentation. On 240 volts a full charge takes about 26.5 to 26.8 h on a 16 A charger, 13.2 to 13.4 h on 32 A, 10.6 to 10.7 h on 40 A and 8.8 to 8.9 h on 48 A. A 48 A charger delivers 11.52 kW to it; reaching the full 19.2 kW takes an 80 A charger, so every class up to 80 A adds speed on this car. NACS charge port (the Tesla-style port). NACS chargers plug in directly; J1772 chargers work with an adapter.

Charge time by charger amps
A charger's amp rating sets its power on a 240 volt circuit; the car then takes the smaller of that and its own onboard limit. Each row is one standard charger rating.
| Charger rating | Power at 240 V | Available 19.2 kW onboard charging module (Premium and OPTIQ-V) | Standard | Against the row above | Tracked chargers at this rating that fit |
|---|---|---|---|---|---|
| 16 A | 3.84 kW | 3.84 kW, 26.5 to 26.8 h | 3.84 kW, 26.5 to 26.8 h | Slowest standard rating | 3 |
| 32 A | 7.68 kW | 7.68 kW, 13.2 to 13.4 h | 7.68 kW, 13.2 to 13.4 h | Adds 3.84 kW | 7 |
| 40 A | 9.6 kW | 9.6 kW, 10.6 to 10.7 h | 9.6 kW, 10.6 to 10.7 h | Adds 1.92 kW | 14 |
| 48 A | 11.52 kW | 11.52 kW, 8.8 to 8.9 h | 11.5 kW, 8.8 to 9.0 h | Adds 1.92 kW | 14 |
| 80 A | 19.2 kW | 19.2 kW, 5.3 to 5.4 h | 11.5 kW, 8.8 to 9.0 h | Adds 7.68 kW | 4 |
Power is amps times 240 volts. Full-charge times divide the EPA wall energy for a full charge (102 to 103 kWh), which already includes charging losses, by the rate the car accepts. The comparison column reads the highest-rated trim. The last column counts chargers in this database rated at exactly that current that plug into this car directly.
Chargers that fit the Cadillac Optiq, by amps
Selection rule, in full: only chargers with a verified price appear; grouped by the charger's rated current; the 5 lowest verified prices in each group. Nothing here is an editorial pick.
Prices were verified at a named seller on October 5, 2026. Rate and full charge assume the 19.2 kW onboard charger; lower-rated trims cap lower, as the table above shows.

Lowest standby draw
Each list is named for its metric and drawn from all 59 chargers that plug in directly, priced or not. Standby draw comes from ENERGY STAR test data and is published for 17 of them.
Vehicle figures come from EPA fuel-economy data (2026); the maximum AC rate is verified against the manufacturer's own documentation. Charger specifications follow the same methodology as every page on this site.
Charge rate depends on which Cadillac Optiq you have
This family does not charge at one speed. 2 different AC intake ratings ship across the 6 trims, and a charger cannot exceed the one in your car. Buying for the higher figure when you own the lower trim buys nothing.
| Trim | Onboard limit | Circuit it can use | Full charge |
|---|---|---|---|
| standard | 11.5 kW | A | 8.8 to 9.0 h |
| available 19.2 kW onboard charging module (Premium and OPTIQ-V) | 19.2 kW | A | 5.3 to 5.4 h |
Intake figures are manufacturer-published, not derived from EPA data. Source: the maker's own documentation. Full-charge times assume 102 to 103 kWh drawn from the wall, which already includes charging losses.
What a full charge costs
Electricity is the whole running cost, and it is the number that varies most by where you live. A full 102 to 103 kWh at the Cadillac Optiq, priced three ways:
| Rate | Cents per kWh | Full charge |
|---|---|---|
| Louisiana, the cheapest state | 12.72 | $12.94 to $13.11 |
| National average | 18.31 | $18.62 to $18.88 |
| Hawaii, the most expensive | 48.00 | $48.82 to $49.49 |
Rates are the EIA residential series, July 2026. Your own utility and any time-of-use plan decide the real figure.
The circuit this car needs
A home charger is a continuous load, so the National Electrical Code sizes both the breaker and the conductor at 125 percent of its draw. A charger matched to this car's 19.2 kW ceiling pulls 80 amps at 240 volts, which needs a 100 amp circuit rather than the 80 amp one the arithmetic alone suggests. That gap is where most installation quotes go wrong.
Of the 59 chargers that plug in directly here, 5 meet or beat the car's ceiling. Going above it changes nothing for this vehicle, though it leaves headroom for a future one that draws more.
Cadillac Optiq home charging questions
- How long does it take to charge a Cadillac Optiq at home?
- On 240 volts, from empty to full: about 26.5 to 26.8 h on a 16 amp charger, 13.2 to 13.4 h on 32 amps, 10.6 to 10.7 h on 40 amps and 8.8 to 8.9 h on 48 amps, and 5.3 to 5.4 h on 80 amps. The Cadillac Optiq accepts up to 19.2 kW of AC, and a full charge draws 102 to 103 kWh from the wall, which already includes charging losses.
- What amp charger can a Cadillac Optiq use?
- It reaches its 19.2 kW onboard limit at 80 A (240 volts). A 48 A charger delivers 11.52 kW to it; reaching the full 19.2 kW takes an 80 A charger, so every class up to 80 A adds speed on this car. 5 of the 59 chargers that plug in directly in this database reach that rate.
- Does a 48 amp charger charge the Cadillac Optiq faster than a 40 amp one?
- Yes. At 40 A it accepts 9.6 kW and at 48 A 11.52 kW, which takes a full charge from about 10.6 to 10.7 h to 8.8 to 8.9 h.
- Which connector does the Cadillac Optiq use?
- NACS charge port (the Tesla-style port). NACS chargers plug in directly; J1772 chargers work with an adapter.
- How much does it cost to charge a Cadillac Optiq at home?
- About $18.62 to $18.88 for a full charge at the national average residential rate of 18.31 cents per kWh (EIA, July 2026). Your own rate decides the real figure, and it varies by more than a factor of four between states.
- How were these chargers chosen?
- Only chargers with a verified price appear; grouped by the charger's rated current; the 5 lowest verified prices in each group. Nothing here is an editorial pick. Nothing is ranked by commission and no charger is called best. Every figure is verified against a primary source or left blank.
Prices and specifications verified October 5, 2026, and re-checked weekly after that. How these numbers are checked.
