What EV Charger Do You Need for a 2025 Cadillac Celestiq?
Many buyers waste money on a 48 amp or 50 amp Level 2 charger that leaves performance on the table. Your car accepts up to 80 amps of AC power, so you need an 80 amp unit to hit the maximum rate. Anything smaller will throttle your charging speed.
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 6.6 hours |
| Range added per hour (Level 2) | about 46 miles |
| Full charge on a 120 V outlet | about 88 hours |
| Range added per hour (120 V) | about 3.5 miles |
| EPA rated range | 303 miles |
| Energy for a full charge | about 126.3 kWh at the wall |
Why 80 amps and not more
The battery holds 126.3 kWh of energy. Feeding that capacity takes an 80 amp Level 2 setup to refill the pack in 6.6 hours. Smaller chargers throttle the current and drag out your wait time. Your car will draw whatever the EVSE allows up to 80 amps, leaving the rest on the table if your hardware falls short. Buying a lesser unit saves very little money while cutting your charging speed down hard.
What the install involves
You need a hardwired setup because plugs and sockets cannot handle continuous 80 amp loads safely. The pro must pull heavy gauge wire and land it on a dedicated 100 amp breaker in your main electrical panel. Ask your sparky to verify your service has enough spare capacity before buying parts. Never attempt this install yourself.
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
- What is the charging speed?
- At 80 amps, the car adds 46 miles of range every hour. A full recharge takes 6.6 hours. The EPA test notes a rate of 38 miles per hour over an 8.0 hour period because standardized tests use varying protocols.
- Can I use a standard wall outlet?
- Level 1 charging on a standard household outlet delivers only 3.5 miles of range per hour. A full tank takes 88 hours. You need a dedicated Level 2 circuit for daily driving.
- What connector does the car use?
- The vehicle has a J1772 connector. Many models in this production run ship with a NACS port and include a J1772 adapter, so check your specific port before ordering gear.
- Will older Tesla destination chargers work?
- You can use a Tesla to J1772 adapter rated for 80 amps to plug into Tesla destination hardware. This opens up more charging locations on the road.
