What EV Charger Do You Need for a 2027 Cadillac Lyriq 19kW Charger?
Many home chargers max out at 40 or 50 amps, but your car can draw up to 80 amps of Level 2 current. Feeding the 120.0 kWh battery requires an 80-amp EVSE to hit the maximum 19.2 kW onboard intake. You need an 80-amp setup and a 100-amp breaker to charge from empty in 6.3 hours.
The numbers
| Maximum AC charging rate | 19.2 kW (80 A) |
|---|---|
| Charger size to buy | 80 A |
| Circuit breaker required | 100 A |
| Outlet / connection | hardwired only |
| Charge port | J1772 |
| Full charge on Level 2 | about 6.3 hours |
| Range added per hour (Level 2) | about 52 miles |
| Full charge on a 120 V outlet | about 83 hours |
| Range added per hour (120 V) | about 3.9 miles |
| EPA rated range | 326 miles |
| Energy for a full charge | about 120.0 kWh at the wall |
Why 80 amps and not more
Matching the car with an 80-amp home unit pushes 52 miles of range into the pack every hour. Lesser hardware throttles the charging speed because the onboard equipment limits current intake. Plugging into a 50-amp or 48-amp supply works fine, but you lose peak charging velocity. The EPA test protocol runs slightly slower at 47 miles per hour, giving a 7.0 hour full charge time due to standard testing variables. Go with the 80-amp requirement if you want the fastest possible turnaround overnight.
What the install involves
This vehicle demands a hardwired installation because an 80-amp draw exceeds the safe limits of standard residential plug outlets. You must call a licensed electrician to pull a heavy-gauge circuit and land it on a 100-amp breaker in your main panel. Ask the electrician to verify that your service has spare capacity before buying hardware. The J1772 connector plugs straight into the port, though this model year falls in the industry transition to NACS and might require checking the physical port first.
Chargers that match this car
The first unit matches your car's full 80 A. The others are slightly slower but cost less.
One of the few home units that can feed an 80 A car. Needs a 100 A circuit.
Adjustable from 16 A to 50 A in the app, which helps if your panel is tight.
Energy monitoring built in. Hardwire it for the full 48 A.

Common questions
- Can I use a standard wall outlet?
- Level 1 charging on a standard household outlet delivers 3.9 miles per hour. Filling the battery this way takes 83 hours. You need a dedicated Level 2 circuit for practical daily driving.
- Why do I need a 100-amp breaker for an 80-amp car?
- Continuous loads require a circuit rated for 125 percent of the maximum draw. Code mandates a 100-amp breaker and heavy wiring to safely handle 80 amps continuously for hours.
- What if my electrical panel lacks room for a 100-amp breaker?
- You can install a smaller charger like a 48-amp or 50-amp unit, or pay an electrician to upgrade your electrical service. Lower amperage takes longer to fill the battery pack.
- Does this car use a Tesla connector?
- This vehicle uses a J1772 connector for home charging. This model year falls in the industry transition to NACS, so confirm your physical port before buying cables or adapters.
