MUSTART 40A Level 2 Portable vs Webasto Go Dual Voltage

Which is the better buy? Side-by-side on rating, price, strengths, and watch-outs — with the published ratings we averaged to get there.

The short answer

Webasto Go Dual Voltage comes out ahead by a narrow margin (4.4 vs 4.7). The gap is mostly about buyers who want the most-trusted brand, weather-resistant build, and Wi-Fi monitoring — and don't need the 40A speed of the Grizzl-E or MUSTART — read the strengths below before deciding.

Ranked #4 in Best Level 2 Portable EV Chargers

MUSTART 40A Level 2 Portable

4.4

$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

Higher ratedRanked #1 in Best Level 2 Portable EV Chargers

Webasto Go Dual Voltage

4.7

$600

The Webasto Go is the premium pick across most 2026 review roundups. NEMA 6P watertight rating, dual voltage auto-detect, and Wi-Fi remote monitoring set it apart from the simpler portable chargers in this lineup. The 32A ceiling is a deliberate Webasto choice — slower than 40A competitors but more compatible with garage outlets and 50A breakers. Best for buyers who want the brand confidence and the future-proof Wi-Fi feature set.

Strengths

— Dual voltage (120V/240V) auto-detects outlet type — plug-and-play across NEMA 5-15 and NEMA 14-50
— 32A on Level 2 delivers up to 7.7 kW (~30 miles/hour)
— NEMA 6P watertight rating — submersible to 3 ft of water

Watch-outs

— 32A ceiling — slower than the 40A Lectron, Grizzl-E Mini, or MUSTART
— Most expensive pick in this round-up
— Wi-Fi setup adds complexity — non-tech users may struggle initially

How they stack up

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.

Webasto Go Dual Voltage

Most weatherproof pick (NEMA 6P) in this lineup. 32A ceiling is lower than the Lectron WiFi 40A, Grizzl-E Mini Connect, and MUSTART 40A. Loses raw amps to those three; wins on weather resistance and brand support. The Lectron Level 1/2 Dual NEMA is the simpler-spec budget alternative.
