  2. Tesla - Universal Wall Connector Level 2 Hardwired Electric Vehicle (EV) Charger – up to 48A– 24’ - White - Front_Zoom
    Top comment

    "Universal charger supports NACS & J1772 Elegantly!...After shipment was delayed to ship out starting Nov30 got this installed in early December and the Tesla “Magic Jack” works well to easily support both J1772 and NACS although all the other car vendors have agreed to adopt NACS Tesla standard starting in 2025 the J1772 will slowly disappear. Supposedly this charger version has support for bi-directional charging when used with a Gateway which we already have because of our Tesla solar and powerwall however Tesla hasn’t activated this feature on their Tesla cars because it could effect powerwall battery sales — still think Tesla should enable this feature as an emergency backup feature to power your home using your Tesla or even non-Tesla cars like the upcoming Volvo EX90 SUV which supports bi-directional support — currently only Cybertruck has this feature enabled but supposedly the model 3 and Y can support this too if enabled by Tesla!...Tesla charger...Asum charger working perfectly fine and easy to setup"
