Lectron 40A Portable Level 2 Charger Review

The cheapest honest route into real 240V charging: a genuine 40 amps on a NEMA 14-50 plug, ETL listed to the EV-charging safety standards, in a unit you can unplug and put in the trunk. Here's exactly what the low price costs.

By Stephen V.Last updated How we pick

There is a category of cheap EV charger that is cheap because it is not really a Level 2 charger — 16 amps on a 240V plug, or an unlisted box with an impressive-sounding number on the label. The Lectron 40A is not one of those. It delivers a genuine 40 amps and 9.6 kW from a NEMA 14-50 plug, which is the maximum any plug-in charger can legally deliver, and it is ETL listed to UL 2594 / UL 2231— the actual EV supply equipment safety standards, assessed by a third party.

What makes it interesting beyond the price is the form factor. This is a portableunit: no hardwiring, no bracket commitment, unplug it and it comes with you to a rental, a relative’s house or a new address. The trade-offs are specific and worth stating plainly — a 16-foot cable where rivals give 25, a two-year warrantyrather than three, no app on the base model, and no published outdoor or IP rating. Below is the full spec picture, the charging math, and who should and shouldn’t buy it.

Lectron 40A Portable Level 2 Charger

One of the cheapest honest ways into real Level 2 charging. Plug it into a NEMA 14-50 outlet, get a genuine 40A / 9.6 kW, and unplug it to take on a trip. No app and a shorter warranty are the trade-offs for the price.

Strengths

  • A real 40A / 9.6 kW at a budget price
  • Plug-in and portable — take it with you, no hardwiring
  • ETL listed to UL 2594 / UL 2231 safety standards

Trade-offs

  • No WiFi or app on the base model — the smart version is a separate SKU
  • Shorter 16 ft cable and a 2-year warranty
  • Brand doesn't publish an outdoor/IP enclosure rating

Our charging-speed math. At 40A (9.6 kW) and ~3.5 miles per kWh it adds roughly 34 miles of range per hour.

Build note. Portable plug-in unit — no hardwiring needed; the base model has no WiFi or app.

Specs read from the manufacturer spec sheet, on July 19, 2026. “Not published” means the brand does not state that figure.

What “portable” actually buys you

Portability is the feature people underrate and then use constantly. Because the Lectron plugs into a NEMA 14-50 rather than being wired into a wall, three things follow. It needs no electricianif a suitable receptacle already exists — you plug it in and you are charging at 9.6 kW. It comes with you, which matters enormously if you rent, and quietly matters even if you own, because chargers outlive addresses. And it travels: campgrounds, many vacation rentals and plenty of relatives’ workshops have a 14-50 hookup, and this unit turns each of those into a Level 2 charging point.

The cost of that flexibility is a ceiling. Any plug-in charger is capped at 40 amps, because the NEC treats EV charging as a continuous load and limits a device to 80% of the circuit rating — and a 14-50 sits on a 50-amp circuit. To go beyond 40 amps you need a 60-amp circuit and a hardwired unit, which is a different kind of purchase entirely. We lay out that fork in hardwired vs plug-in.

Charging speed, worked out

At 40 amps and 240 volts the Lectron delivers 9.6 kW(40 × 240 = 9,600 watts). At our standard reference of about 3.5 miles of range per kWh, that is roughly 34 miles of range per hour.

Put that against real use. The average US driver covers well under 50 miles a day, so an evening plug-in returns a full day’s driving in about ninety minutes and you still have the entire night spare. A 48-amp charger would do it in about seventy-five minutes instead. That six-mile-per-hour difference is what a much more expensive install buys you, and for most single-EV households it is genuinely invisible — the argument we work through in 40 amps vs 48 amps. Where the Lectron’s speed is transformative is against the 120V cable that came with your car: Level 1 adds roughly 3 to 5 miles per hour, so this is close to a tenfold jump. That comparison is in Level 1 vs Level 2.

Where the money was saved

Every cheap product cuts something, and a review that doesn’t say what is useless. Here is exactly where the Lectron is thinner than a $450 wall charger.

  • Cable length: 16 feet.This is the most consequential one. Rivals give 25 feet, and the difference decides whether you can reach a charge port on the far side of the car, or park in the second bay. Measure the route before you buy — our long-cable guide explains how, and 16 feet disappears faster than people expect once you account for mounting height and going round the bodywork.
  • No published outdoor or enclosure rating.Lectron doesn’t publish an IP or NEMA figure for this unit, so we record it as “Not published” rather than guessing. Practically: keep it in a garage or under cover. If it must live outside, buy something with a stated rating — see our outdoor picks.
  • Two-year warranty. Most of the competition offers three. On a product you expect to run every night for a decade, that is a real difference in coverage, if a modest one in practice.
  • No app on the base model. The WiFi version is a separate SKU. If you are on a time-of-use rate, check that your car can schedule charging before you rely on the charger to do it — almost all can, which is why we don’t treat this as disqualifying.

What it did not cut is the part that matters most: the safety listing. ETL listing to UL 2594 and UL 2231 means a third party assessed it against the standards written for EV supply equipment and personnel protection. That is the line we would not cross for any saving, and the Lectron stays on the right side of it.

The outlet is the real project

If you already have a NEMA 14-50in the garage, this charger costs you nothing but its purchase price and you are done. If you don’t, adding one is the actual job — and it is a proper electrical job: a 50-amp circuit, appropriately sized conductors, and under current code generally GFCI protection on the circuit, usually via a GFCI breaker. Our installation cost guide prices it out, and the DIY guide explains where the homeowner line usually falls.

One thing not to do: don’t plan to run it from a dryer outlet with an adapter and hope. Dryer receptacles are 30-amp circuits — NEMA 14-30, or the older three-wire 10-30 with no separate ground — and that caps you at 24 amps continuous even in the best case, on a circuit that was never designed for a six-hour continuous load.

Who should buy it — and who should skip it

Buy itif price is the binding constraint, if you rent, or if you want a charger that travels — we rank it against the other travel units in best portable Level 2 chargers. It is the cheapest genuinely-certified way to get real 40-amp Level 2 charging, it needs no electrician when a 14-50 already exists, and the portability is a real feature rather than a marketing word. It is also a sensible second charger for a household that already has a wall unit and wants something for trips.

Skip itif the charger will be permanently mounted on an exposed wall — there is no published weather rating, and that is not a spec to improvise on. Skip it if you need more than 16 feet of reach, which is a more common problem than the price difference suggests; the EVIQO and Emporiaboth give 25 feet. And skip it if you want scheduling and energy data from the charger itself, unless you buy Lectron’s separate WiFi version. For everyone else, it does the one job a charger has to do, at the lowest honest price we can find.

Frequently asked questions

Is the Lectron 40A a real Level 2 charger?

Yes. It runs on 240 volts and delivers a full 40 amps / 9.6 kW, which is the maximum a plug-in charger can deliver under the NEC's continuous-load rule on a NEMA 14-50 circuit. It is ETL listed to UL 2594 and UL 2231, the safety standards written for EV supply equipment — so it is a properly certified Level 2 unit, not a 240V cable with a big number on the box.

How fast does the Lectron 40A charge?

At 40 amps and 240 volts it delivers 9.6 kW. Using our reference of about 3.5 miles of range per kWh, that's roughly 34 miles of range per hour — enough to replace a normal day's driving in under two hours, and to fill essentially any battery overnight. That is about six miles per hour less than a 48-amp charger, a gap most drivers never notice.

Can I use the Lectron 40A outdoors?

Lectron does not publish an outdoor or IP enclosure rating for this unit, so we don't claim one — our spec table shows it as 'Not published', which is itself the finding. Treat it as a garage or under-cover charger. If your charger has to live on an exposed wall, buy a unit with a published NEMA or IP rating; our outdoor roundup covers those.

Does the Lectron 40A have WiFi or an app?

Not on the base model. Lectron sells a separate WiFi version as its own SKU. For most owners this matters less than it sounds, because nearly every modern EV can schedule charging from the car's own app — which is where scheduling arguably belongs anyway, since the car knows its state of charge.

What outlet does it need?

A NEMA 14-50 — the four-prong 240V receptacle used for ranges and RV hookups, on a 50-amp circuit. It is not a dryer outlet: those are usually 30-amp NEMA 14-30 or the older three-wire 10-30, which limits you to far less current and, in the 10-30 case, has no separate ground. If you don't have a 14-50, adding one is a straightforward electrician job and is often the whole project.

Is a portable charger worth it if I own my home?

It can be, for two reasons: it is the cheapest way to get real Level 2 charging, and it doubles as a travel charger for trips to places with a 14-50 hookup — campgrounds and many rentals have them. What you give up is cable length, weather rating and app features. If the charger will be permanently mounted on an exposed wall, buy a wall unit instead.
