What EV Charger Do You Need for a 2026 Chevrolet Blazer EV SS?
Forty-eight amps is the magic number for your Chevrolet Blazer EV SS. A 48 A Level 2 charger fills the 119.8 kWh battery in 10.4 hours. You need this specific setup to get the most out of the 11.5 kW onboard charger.
The numbers
| Maximum AC charging rate | 11.5 kW (48 A) |
|---|---|
| Charger size to buy | 48 A |
| Circuit breaker required | 60 A |
| Outlet / connection | hardwired (a 48 A EVSE must be hardwired -- no household receptacle is rated for it) |
| Charge port | J1772 |
| Full charge on Level 2 | about 10.4 hours |
| Range added per hour (Level 2) | about 29 miles |
| Full charge on a 120 V outlet | about 83 hours |
| Range added per hour (120 V) | about 3.6 miles |
| EPA rated range | 302 miles |
| Energy for a full charge | about 119.8 kWh at the wall |
Why 48 amps and not more
Your car accepts up to 48 amps of alternating current. Buying a larger 50 A unit will not speed up the charge because the vehicle caps its intake at 48 amps. Pumping fewer amps into the port only drags out the wait time without saving money on the hardware. Feeding the battery at 48 amps yields 29 miles of range for every hour plugged into Level 2. The EPA test protocol runs slightly slower at 27 miles of range per hour, stretching a full charge to 11.2 hours.
What the install involves
A 48 A load requires a 60 A breaker to protect the wiring run. No household wall receptacle handles 48 amps continuously, so you must hardwire the EVSE directly to the circuit. Have a licensed electrician check your main electrical panel for spare capacity before buying parts. They need to pull heavy gauge copper wire, land it on the new two pole breaker, and mount the unit securely to the wall.

Common questions
- Can I plug this car into a standard wall outlet?
- You can plug into a standard household outlet using Level 1 equipment, but it adds only 3.6 miles of range per hour. Filling the battery from empty this way takes 83 hours. Use a 240 volt Level 2 setup for daily driving.
- What connector does the car use?
- This vehicle features a J1772 connector. Many 2025 and newer vehicles ship with a NACS port while including an adapter, so confirm your physical port before ordering hardware.
- Will a 50 A charger charge the car faster than a 48 A unit?
- No. The onboard charger maxes out at 48 amps, so the vehicle leaves the extra 2 amps on the table.
- Do I need a hardwired charger or can I use a plug?
- You must hardwire a 48 A charger. No household receptacle is rated to handle that continuous electrical load safely.
