Tesla recently unbundled the High Power Wall Connector and Dual Charger options. This has left many customers wondering why they would need the Dual Charger option. There are a couple of reasons why the Dual Charger option is a good thing to have. • If you install a High Power Wall Connector and wish to get the full 80A capacity out of it, you will need dual chargers. (However, for home charging I believe the HPWC is overkill. If you charge at night, why should it matter if it takes 3 hours or 6 hours to charge your car?) • Dual chargers do come into their own on other occasions, however. On several occasions I have charged at a Tesla store, using their HPWC. This option saved me hours of waiting compared to using a generic 30A ChargePoint. Likewise, when your car is at a Tesla service center, your car can be charged on a HPWC while being serviced, increasing the likelihood that your car will be fully replenished when you pick it up. NOTE: Dual Chargers are not necessary for supercharging.
