What EV Charger Do You Need for a 2026 Mercedes-Benz CLA350 with EQ Tech?
You need a 48 amp Level 2 charger to fill your battery overnight in 8.2 hours. Your car pulls 11.0 kW maximum on alternating current. The onboard charger caps your intake speed. Buying a larger unit wastes money.
The numbers
| Maximum AC charging rate | 11.0 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 8.2 hours |
| Range added per hour (Level 2) | about 38 miles |
| Full charge on a 120 V outlet | about 63 hours |
| Range added per hour (120 V) | about 5.0 miles |
| EPA rated range | 312 miles |
| Energy for a full charge | about 90.5 kWh at the wall |
Why 48 amps and not more
Your car accepts up to 48 amps through its onboard hardware. Feeding it a larger 60 amp or 80 amp charger changes nothing. The vehicle draws what it handles and ignores the rest. A 48 amp supply delivers 38 miles of range every hour you stay plugged in. Going smaller extends your overnight wait unnecessarily.
What the install involves
You must install a 60 amp breaker for a 48 amp continuous load. Hardwiring is mandatory because household outlets fail under this sustained current draw. Hire a licensed electrician to run the heavy copper wire from your main panel to the garage wall. Never attempt this branch circuit work yourself.

Common questions
- Can I use a standard wall outlet for Level 2 charging?
- No. A standard household outlet only provides Level 1 speed which takes 63 hours to fill the 90.5 kWh battery.
- What happens if I buy a 50 amp charger like the ChargePoint Home Flex?
- Your car limits the draw to 48 amps anyway. The extra capacity goes unused.
- Why does the EPA test show 8.8 hours instead of 8.2 hours?
- The official EPA test cycle factors in lower power delivery phases and charging losses during the full run. Real world conditions at maximum output hit the 8.2 hour mark.
- Does this car use a J1772 connector?
- Yes. This model year falls in the industry transition and may include a NACS port with an adapter, so check your specific physical port before ordering.
