Cadillac Optiq home charger: charge time and which amps it can use

Cadillac Optiq home charger buying guide: chargers matched to it

The Cadillac Optiq takes at most 19.2 kW from a home charger, which it reaches at 80 A. The lowest verified price for a charger that fits its charge port and reaches that rate is $1,013.20, for the Autel MaxiCharger 80A 19.2kW Residential: 80 A, hardwired. No plug-in charger we track reaches it: on an outlet a charger may draw at most 80 percent of the outlet's rating, and the fastest plug-in option delivers 9.6 kW (10.6 to 10.7 h to full), from $179.00 for the MUSTART Tesla Portable (NACS). A higher-rated charger charges it no faster: the car caps the rate at 19.2 kW, so the one matching charger rated above 80 A (from $6,300.69) delivers the same 19.2 kW at its rating as the Autel MaxiCharger 80A 19.2kW Residential at $1,013.20. Spending less buys a slower charge: the MUSTART Level 1 & 2 Tesla EV Charger, 16 A (NEMA 5-15 and 6-20 plugs, 25 ft cord), 16 A at $109.00, takes 26.5 to 26.8 h to fill it against 5.3 to 5.4 h.

Prices were verified at the named seller on the date the charger's own page shows, all on or after October 26, 2026. Rate and full charge use the 19.2 kW onboard limit of the highest-rated trim and the EPA wall energy for a full charge (102 to 103 kWh).

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.

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.

How these Level 2 times compare with a standard 120 volt outlet, in hours to full and miles added overnight for every vehicle family, is in Level 1 vs Level 2 charging compared by vehicle.

Charging the Cadillac Optiq on a regular 120 volt outlet

A standard household outlet is Level 1 charging. On a 15 A household circuit it can supply 12 A for hours at a time, which is 1.44 kW: far below the car's 19.2 kW limit, so the outlet, not the car, sets the speed.

The 120 V figures divide the EPA wall energy for a full charge (102 to 103 kWh) by 1.44 kW, and multiply 1.44 kW by the EPA range per wall kWh of the lowest and highest configuration, the same arithmetic as the Level 2 table above. EPA measures that energy on a Level 2 charger; the same wall energy is assumed on Level 1. The 15 A circuit's 12 A ceiling is the NEC 125 percent continuous-load rule (210.20(A)).

Cadillac Optiq charge port by model year

The port is the one a home charger plugs into. A year with two rows has a trim or build split. An adapter covers either direction.

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 26, 2026. Rate and full charge assume the 19.2 kW onboard charger; lower-rated trims cap lower, as the table above shows.

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.

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:

Rates are the EIA residential series, August 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 60 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.
