How they stack up

Lectron 40A J1772 Portable (Wi-Fi)

Splits the difference between the smart Grizzl-E Mini Connect and the bare-bones Splitvolt: it has an LCD and an optional Wi-Fi app like the Grizzl-E but a shorter cord than the MUSTART, and it throttles below its rated 40A when warm.

Splitvolt 40A NEMA 14-50

The lightest and usually cheapest option, ideal for travel, but the most basic: unlike the Grizzl-E Mini Connect and Lectron it has no app or scheduling, and its base cord is shorter than the 25-foot MUSTART and Grizzl-E cables.
