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.

MUSTART 40A Level 2 Portable

A value alternative to the Grizzl-E Mini Connect with the same 40A output and an equally long 25-foot cable, but no Wi-Fi or app; it costs more than the Splitvolt but offers a longer cord and adjustable current.
