How long does it take to charge a Cadillac Optiq at home?

The Cadillac Optiq accepts up to 19.2 kW of AC, so a charger that meets or beats that fills it as fast as the car allows. A full charge draws 102 to 103 kWh from the wall, which is about 5.3-5.4 h on the fastest compatible charger in this list. A charger rated above 19.2 kW does not charge it any faster.

What size charger does a Cadillac Optiq need?

Match the car's 19.2 kW ceiling and stop there. 5 of the 58 chargers that plug in directly in this database reach it. Anything more powerful is spare capacity for a future car, not extra speed for this one.

How much does it cost to charge a Cadillac Optiq at home?

About $18.75 to $19.01 for a full charge at the national average residential rate of 18.44 cents per kWh (EIA, May 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; ranked by charge rate on this car, then by that price; at most two per brand; ten rows at most. 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.

Home chargers for the Cadillac Optiq

2026 model year, 6 EPA-listed configurations

Max AC charging rate: 19.2 kW
Full charge (wall energy): 102 to 103 kWh
EPA range: 250 to 317 mi
Cost per full charge: about $18.75 to $19.01

The Cadillac Optiq accepts up to 19.2 kW from a home charger depending on trim. NACS charge port (the Tesla-style port). NACS chargers plug in directly; J1772 chargers work with an adapter. 5 of the 58 chargers that plug in directly reach that rate, and every one of them charges this vehicle at exactly the same speed: a more powerful charger will not charge this car faster. The numbers that still separate them are verified price, cable length, and warranty.

11.5 kW: standard
19.2 kW: available 19.2 kW onboard charging module (Premium and OPTIQ-V)

A full charge costs the same on any Level 2 charger: energy is energy. The figure above uses the national average residential rate (EIA, May 2026); the charging cost calculator has your state's number.

Spec leaders

Each list is named for its metric and drawn from all 58 chargers that plug in directly, priced or not. Standby draw comes from ENERGY STAR test data and is published for 16 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
Idaho, the cheapest state	12.35	$12.56 to $12.73
National average	18.44	$18.75 to $19.01
Hawaii, the most expensive	52.00	$52.88 to $53.61

Rates are the EIA residential series, May 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 58 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.
