Lectron Level 1 & 2 Tesla charger review

One NACS portable for a standard outlet and a 14-50, with the current adjustable on both. Here is what Lectron publishes -- and the one figure on its page to ignore.

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.

A Tesla driver who charges in more than one place usually needs two things: Level 2 at home and something that works from an ordinary outlet elsewhere. This unit is both. We have not tested one; figures come from Lectron's product page, linked at the foot of this page.

Level 1 and Level 2, honestly

The arithmetic at 3.5 mi/kWh

Level 1 at 12 A: 12 x 120 = 1.44 kW, about 5 miles of range per hour

Level 2 at 16 A: 16 x 240 = 3.84 kW, about 13 miles per hour

Level 2 at 40 A: 40 x 240 = 9.6 kW, about 34 miles per hour

Who it suits

  • A Tesla driver who charges in several places -- a 14-50 at home, a standard outlet at a relative's. Dual-voltage portables.
  • A second charger for a Tesla household. The included wall mount makes it a tidy fixture beside a 14-50.

Full published specifications, and the case against it.

1. Level 1 and Level 2 in one

Lectron Portable Level 1 & 2 Tesla NACS EV Charger

Lectron · NACS · 40 A / 9.6 kW · 20 ft cable

One NACS portable for a standard outlet and a 14-50: 8 to 12 A on 120 V, 16 to 40 A on 240 V, with switchable plugs. The most flexible single unit for a Tesla on the move.

What is good

  • Runs from a standard outlet and a 14-50 with the same unit
  • Adjustable current, so it can be turned down for a weaker circuit
  • Published UL 2594 / UL 2231 certification

What is not

  • NACS only -- a J1772 car needs an adapter
  • On 120 V it is still Level 1: about 5 miles of range per hour at best
  • 20 ft of cable, per Lectron's FAQ -- measure the run before relying on it

Skip this if: Skip it if a non-Tesla might use it -- it is NACS only -- or if you will only ever charge on 240 V.
