Ranked #4 in Best Level 2 Portable EV Chargers
ELEGRP 40A Portable Level 2 EV Charger
2 sources$210as of Oct 17

The ELEGRP ECP24-40A0-01 is a 240 V, 40 A (9.6 kW) portable Level 2 charger with a NEMA 14-50 plug, a J1772 connector and a 25 ft cable. Jim's EV Adventures measured close to 10 kW going into a Chevrolet Bolt EUV, praised the adjustable 16-40 A current and long cable, and scored it 4.35 out of 5; Technically Jeff rated it 9.0 out of 10 for its solid 40 A charging, ETL certification and dual home and portable use. Both reviewers note it has no app or smart functionality. It suits drivers with a 14-50 outlet who want plain, full-speed charging and a long reach; anyone who wants app scheduling or energy tracking should look elsewhere.

Strengths
  • — Delivers full 40 A Level 2 charging; Jim's EV Adventures saw close to 10 kW on a Bolt EUV
  • — Charging current adjusts on the unit from 16 A to 40 A to suit smaller circuits
  • — 25 ft cable, one of the longer options at its price
Watch-outs
  • — No app or smart features; scheduling is limited to the on-unit delay timer
  • — Cable is a little stiff and the wall-mount plastic feels weak
  • — Technically Jeff rates the J1772 connector only average

J+ BOOSTER 2

J+ BOOSTER 2
2 sources

The J+ Booster 2 is a 40 A, dual-voltage portable J1772 charger with an aluminium body and a 21 ft or 25 ft cord. It takes swappable NEMA 14-50 and NEMA 5-15 adapters. InsideEVs drove two pickup trucks over it, froze the cord and submerged the unit, and the charger kept working; it scored 4.4/5. EVchargerReviews.net (4.7/5) ran it at 40 A for hours with no thermal throttling and called it the most premium portable unit it had tested. It suits drivers who want one rugged charger for the garage and the road. Anyone with an existing NEMA 14-50 outlet installed upside down, or on a tight budget, should look elsewhere.

Strengths
  • — Kept working after InsideEVs drove an F-150 Lightning and a Rivian R1T over it
  • — Ran for hours at 40 A with no thermal throttling in a 50 kWh stress test
  • — IP67-rated, and it passed InsideEVs' submersion test after more than 30 minutes underwater
Watch-outs
  • — Input cables are only about a foot long, so outlet position and orientation matter
  • — The most expensive portable charger EVchargerReviews.net has tested
  • — The cord earned only an average score in InsideEVs' deep-freeze test

How they stack up

ELEGRP 40A Portable Level 2 EV Charger

Like the MUSTART 40A Level 2 Portable and the Splitvolt 40A NEMA 14-50, the ELEGRP is a 40 A plug-in charger without smart features, but its 25 ft cable is its main selling point. Buyers who want app control should compare the Grizzl-E Mini Connect (40A) and the Lectron 40A J1772 Portable (Wi-Fi), whose connected features the ELEGRP lacks.

J+ BOOSTER 2

The Booster 2 is a premium alternative to the Grizzl-E Mini Connect (40A) and the Splitvolt 40A NEMA 14-50. Its main selling points are a crush-rated aluminium body, IP67 sealing and swappable locking plug adapters. Its controls are a single button and LED indicators, so buyers who want an LCD and app scheduling may prefer the Lectron 40A J1772 Portable (Wi-Fi).
