The MUSTART 40A is a long-running, widely-sold portable Level 2 charger that delivers the full 9.6 kW with a generous 25-foot cable for a moderate price. ElectricVehicleGeek scored it 8.3/10, EV Adept buyers rate it 4/5 and Technically Jeff called it a solid charger worth considering under $300. The main cautions are reports of inconsistent safety certifications and the lack of smart features.

Strengths
  • Full 40A / 9.6 kW output, about 2.5x faster than a 16A Level 2 charger
  • Long 25-foot J1772 cable, among the longest in this group
  • Adjustable current (15/25/40A) for use on smaller circuits
Watch-outs
  • Some buyers and electrical inspectors have flagged questionable certification marks
  • No Wi-Fi or app, and no scheduling on the base portable model
  • A minority of users report J-plug or charging-port issues over time

$255.54as of Jun 7

The Splitvolt 40A is the lightweight, low-cost, no-frills option, weighing just 7.7 lbs with a travel bag and charging at the full 9.6 kW.

It's the pick for travel and tight budgets, not for smart-home charging.

  • Very portable at about 7.7 lbs and ships with a travel bag
  • Full 40A / 9.6 kW NEC-safe charging with no installation required
  • IP55-rated, cETLus-certified weather-resistant enclosure
Watch-outs

  • Shortest cord in the base version at about 16 feet
  • Some owners report the charger shutting down after a power outage

How they stack up

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.

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.
