What 40A means
A 40A charger delivers about 9.6 kW on a 240V circuit. That is enough for many EV owners who charge overnight and drive a normal daily distance.

48 Amp vs 40 Amp EV Charger: Which One Should You Buy?
A 40A charger is already a strong Level 2 home charger. A 48A charger is faster, but it also needs a hardwired installation and a dedicated 60A breaker. Here is the practical difference for Canadian and North American EV owners.

What 48A means
A 48A charger delivers about 11.5 kW. The extra power helps any compatible EV recover range faster, especially when you want shorter charging sessions or need the car ready again quickly.
The key tradeoff
A 48A charger normally requires hardwired installation on a 60A dedicated circuit. That is standard for high-output home charging, but it should be installed by a licensed electrician.
When a 48A charger is worth it
- You want faster home charging. Any EV with an onboard AC charger that can accept the extra power can benefit from 48A output, whether it is a sedan, crossover, SUV, or truck.
- Your car can accept the power. Many modern EVs can use around 11 kW of AC charging. If your onboard charger is limited to less, the car will simply take what it can.
- You want faster overnight recovery. The difference between 9.6 kW and 11.5 kW matters most when you arrive home with a lower battery and need the car ready the next morning.
- You have limited charging windows. If you charge during off-peak hours, between errands, or after a long commute, higher output gives you more usable range in less time.
- You prefer a permanent installation. Hardwired chargers avoid repeated plug and receptacle wear and can be a cleaner long-term home charging setup.
