It all depends on your electricity tariffs. I try to charge my electric car during off-peak hours whenever possible. Because at the end of the month, thanks to this, I will receive a lower electricity bill. But, in principle, if you use ev charger equipment from Cyber Switching, then it does not consume much energy. And it charges fast enough. It is better to choose Level 2 Charger, as it is more economical than Level 3. But it charges much faster than, for example, Level 1.
