How this page is funded: we earn a commission if you buy through our Amazon links, at no extra cost to you. It does not change what we recommend, and we say plainly when the honest answer is to buy nothing. Full disclosure.

The short version: a plug-in Level 2 charger that runs from a NEMA 14-50 and drops to a standard household outlet with the included adapter. It is the travel unit, not the garage unit, and it is priced accordingly.

What it delivers

The arithmetic

On a NEMA 14-50 at 32 A: 32 x 240 = 7.7 kW, about 27 miles of range per hour

Over a 10-hour night: about 270 miles

On a standard 120 V outlet with the adapter: about 5 miles per hour

The outlet decides the speed. The charger just has to be able to use both.

Lectron portable Level 2 charger

Lectron · J1772 · 32 A / 7.7 kW · 21 ft cable

A plug-in portable that runs at Level 2 speed from a NEMA 14-50 and drops to a standard wall outlet with the included adapter. The travel unit, not the garage unit.

What is good

  • Level 2 speed from a NEMA 14-50 without an installed charger
  • Falls back to a standard household outlet with the adapter
  • Small enough to keep in the trunk

What is not

  • 32 A ceiling, meaningfully slower than a 48 A wall unit
  • Not weather-rated for permanent outdoor mounting
  • Repeated plugging and unplugging wears a NEMA 14-50 receptacle faster than a hardwired unit

Skip this if: Skip it if this is your only charger and you have a garage. A wall unit is faster and does not live in your trunk.

Where it fits

The case for a unit like this is flexibility rather than speed. It works at a rental with a dryer outlet, at a relative's house, at a campground with the right adapter, and at home if you already have a suitable 240-volt socket. It also comes with you when you move, which a hardwired charger does not.

Against the J+ Booster 2, the Lectron gives up amperage and the ruggedized body, and costs less. Against a wall unit, it gives up speed, weather rating and a permanent connection.

Who should not buy it

  • You have a garage and are staying put. A wall unit is faster, tidier and does not live in your trunk.
  • You need the fastest possible portable. The J+ Booster 2 runs at 40 A.
  • You want it mounted outside permanently. Portables are not rated for that. Outdoor units.
  • You will unplug it daily. Repeated cycling wears a NEMA 14-50 receptacle faster than it was designed for -- what to specify.
