What EV Charger Do You Need for a 2024 Chevrolet Blazer EV?
A full charge takes 10.3 hours on a Level 2 setup. That timeline easily fits into standard overnight parking hours. You need a 48 amp EVSE to hit this speed.
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 10.3 hours |
| Range added per hour (Level 2) | about 31 miles |
| Full charge on a 120 V outlet | about 82 hours |
| Range added per hour (120 V) | about 3.9 miles |
| EPA rated range | 324 miles |
| Energy for a full charge | about 118.7 kWh at the wall |
Why 48 amps and not more
Your car draws up to 48 amps of current. Feeding it a 48 amp Level 2 charger lets you hit the maximum onboard charging rate of 11.5 kW. Buying a larger unit will not speed up your charging time because the vehicle onboard charger limits the intake. Lower amperage hardware slows down your replenishment rate. Match the 48 amp recommendation to recover 31 miles of range per hour.
What the install involves
You must hardwire a 48 amp EVSE because no household receptacle is rated for that continuous load. A licensed electrician needs to pull a dedicated circuit, land a 60 amp breaker in your panel, and verify spare capacity. Do not attempt a DIY install on this amperage. Hardwiring eliminates the failure points of high temperature plug connections.

Common questions
- Can I plug this car into a standard wall outlet?
- Yes, but Level 1 charging takes 82 hours for a full battery and adds only 3.9 miles of range per hour. You will want a Level 2 setup for daily driving.
- What connector does the car use?
- The vehicle uses a J1772 connector for AC Level 2 charging. Every non Tesla EV sold in North America through 2024 uses this standard.
- Why does the EPA estimate differ from the maximum charge time?
- The EPA rated Level 2 charge time is 11.0 hours at 29 miles per hour. Standard testing protocols account for charging losses and tapering rather than peak raw speed.
- Can I use Tesla destination chargers?
- Yes, if you buy a J1772 adapter rated for the job. It lets your car hook up to Tesla hardware safely.
Other vehicles
Charging times derived from EPA data for the 2024 Chevrolet Blazer EV (covering 2 EPA trim listings). Electrical requirements follow NEC 625.41, which sizes a circuit at 125% of a continuous load. Always have a licensed electrician verify your panel.
