## What reviewers say

**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.)
