Wall Connector (Gen 3)
Well regarded but dated: InsideEVs' two hands-on reviews rate it 4.45/5 as a competitively priced $500, 48-amp Wi-Fi charger with the thinnest cable of any high-powered Level 2 EVSE they'd tested, docking it for the shortened 18-foot cord, a cable that stiffens in cold weather, and smart features that stayed unactivated for nearly a year. Wirecutter's 2026 guide lists it among tested competition rather than picks, citing hardwired-only installation, NACS-only compatibility, and weaker weatherization. (3 sourced reviews, 3 lab-tested.)
Praised: Competitive $500 price for a 48-amp Wi-Fi-connected smart charger versus pricier rivals like ChargePoint Home Flex and JuiceBox; Thin, easy-to-manage cable — the thinnest of any high-powered (40-amp+) Level 2 EVSE the tester had used; High overall hands-on rating: 4.45/5 via ChargerRater scoring.
Flagged: 18-foot cable is shorter than the Gen 2's 24 feet — called a significant problem and a huge mistake; rivals ship 23-25-foot cords; Cable becomes very stiff and unmanageable in prolonged cold temperatures (cable deep-freeze test); Smart-charging features were unannounced at launch and still not enabled nearly a year later.
