If you drive high kilometres daily, e.g. used for courier services or rideshare, then an 11 or 22-kW EV charger would be helpful to recharge your EV quickly. The EV you drive, or own must be able to charge at these rates to take advantage of the higher charging rate. For most domestic EV owners, a 7kW charger is suitable and all you need for daily commuting and running around.
