The MUSTART 40A is the value 40A pick — it hits the same 9.6 kW output as the Grizzl-E Mini Connect and Lectron WiFi 40A for substantially less. The catch is no Wi-Fi smart features, which doesn't matter to users who'll just plug in and walk away. The 25 ft cable is genuinely useful — it's the longest in this lineup and means the outlet doesn't need to be next to the car. The on-device delay timer covers the off-peak-charging scenario without an app.
