$470

The Grizzl-E Mini Connect is the rugged 40A premium pick. Cast aluminum enclosure that survived an F-150 drive-over test, 40A output for the fastest Level 2 charging here, and a Wi-Fi smart-charging app round out the feature set. The 4-adapter NEMA kit means it plugs into garages, RV outlets, and most standard 30/50A receptacles without buying extra gear. Trade-offs are weight and the $100 premium over MUSTART for equivalent 40A output.

Strengths
  • 40A output delivers up to 9.6 kW — fastest Level 2 charging in this round-up
  • Cast aluminum NEMA 4X enclosure — survived being run over by an F-150 in durability testing
  • Wi-Fi-enabled with smart scheduling, monitoring, and energy use tracking
Watch-outs
  • Heavier than the Lectron WiFi 40A or MUSTART 40A
  • Premium pricing — more expensive than the MUSTART 40A by ~$100
  • App setup requires Wi-Fi connection — pure offline use loses smart features

Ranked #4 in Best Level 2 Portable EV Chargers
MUSTART 40A Level 2 Portable
$270

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.

Strengths
  • 40A output at the lowest price in the round-up's 40A tier
  • Adjustable current settings (12A/16A/24A/32A/40A) for varied circuit support
  • Delay timer for scheduling off-peak charging without app dependency
Watch-outs
  • No Wi-Fi smart features like the Webasto Go, Grizzl-E Mini Connect, or Lectron WiFi 40A
  • Plastic enclosure with ETL certification
  • MUSTART's brand support is weaker than Webasto's or Grizzl-E's

How they stack up

Grizzl-E Mini Connect (40A)

Most durable construction. Ties with the Lectron WiFi 40A and MUSTART 40A on amp output but exceeds them on enclosure rating. More expensive than the MUSTART 40A; cheaper than the Webasto Go. Includes more NEMA adapters out of the box than any other pick here.

MUSTART 40A Level 2 Portable

Best 40A value. Same output as the Grizzl-E Mini Connect and Lectron WiFi 40A at lower price. No Wi-Fi like the three premium picks. Longest cable (25 ft). Plastic enclosure trails the Grizzl-E's cast aluminum and Webasto's submersible build.
