Lectron NACS Portable vs Lectron J1772 Portable

The same dual-level Lectron portable in two connector flavors — the right one is decided entirely by your car's charge port.

The short answer

Quick picks

#ad · Live prices from the Amazon Product API, as of Jul 27, 2026. Where we have no verified live price, we show none — we would rather leave a gap than print a number that has gone stale.

These are the same dual-level Lectron portable in two connector types, so the choice is not about quality — it is about your car's charge port. Buy the NACS (Tesla-style) version if your car has a native NACS port (a Tesla or a 2025-onward NACS car). Buy the J1772 version if your car has a J1772 port, which is most non-Tesla EVs.

This is the rare comparison with a factual answer rather than a judgment call. We compile published specs and owner reports and explain which one fits; we have not bench-tested either.

What is identical

Almost everything. Both are dual-level portables— a 240-volt (NEMA 14-50) plug for full Level 2 speed and a 120-volt (5-15) plug for a standard outlet — with adjustable current from 8 to 40 amps. Both charge at the same ~25–30 miles of range per hour on 240 volts, both travel in the trunk, and both suit a renter. The hardware and the experience are the same.

The only difference: the plug

The connector on the end is the whole distinction. The NACS version ends in a Tesla-style plug, so a NACS-port car plugs straight in with no adapter. The J1772 versionends in a J1772 plug for the majority of non-Tesla EVs. Buying the wrong one means needing an adapter you should not have to buy — so match it to your car.

How to choose in one step

Open your charge port and look, or check the manual. Tesla and most 2025-and-later cars from the brands adopting the standard use NACS; nearly every other EV of the last decade uses J1772. The NACS vs J1772 guide shows the two connectors side by side if you are unsure. That is the entire decision.

The one-line answer: same charger, different plug. NACS port, buy the NACS version; J1772 port, buy the J1772 version. Do not overthink it.

The verdict

There is no better or worse here — only the right connector for your car. Match the plug to your charge port and you get the same flexible, dual-level, adjustable Lectron portable either way. If you might change cars across the connector divide, note that an adapter can bridge a mismatch in a pinch, but buying the correct connector from the start is cleaner. Both sit in our portable roundup.

A NACS charger that is not bolted to anything — 240-volt speed at home, a 120-volt plug for the road, and it moves when you do.

Pros

  • Ships with both a 240-volt 14-50 plug and a 120-volt 5-15 plug, so it is a home charger and a road-trip cord in one
  • Current adjusts from 8 to 40 amps, which lets you dial it down for an unfamiliar outlet instead of hoping
  • Nothing is fixed to the wall — it goes in the trunk, and it leaves with you when you move

Cons

  • A brick on a hook rather than a tidy mounted box
  • No app or energy monitoring, and 40 amps is the plug-in ceiling

Don't buy this if…

…you want a permanent, tidy wall install with per-charge energy data. A portable trades the mounted look and the app for the ability to come with you.

Pros

  • Ships with both a 240V (14-50) and a 120V (5-15) plug, so it works at home and at a standard outlet
  • Adjustable current means you can dial it down for a weaker circuit
  • Packs into a trunk — a genuine travel charger, not just a wall unit

Cons

  • A portable brick lives on the floor or a hook, not mounted like a wall unit
  • 40-amp draw needs a properly rated 14-50 outlet — do not run it flat-out on a worn receptacle

Don't buy this if…

…you want a permanent, tidy wall installation and never travel with the charger. A hardwired unit like the Wallbox looks cleaner and stays put.

How we picked

We do not run a testing lab

We compiled published specifications from manufacturer manuals and spec sheets, verified the safety listings (UL / ETL), computed the real running and installation costs, checked the wiring math against the NEC continuous-load rule, and read aggregated owner reviews — then scored each product against a published rubric. The scores are judgments from documented research — they are not bench measurements, because we do not have a test lab and we are not going to pretend we do. Every spec and cost figure is cited in Sources.

Questions

Frequently asked

What is the difference between the Lectron NACS and J1772 portables?

Only the connector. Both are the same dual-level (120V/240V), 8–40 amp adjustable portable; the NACS version has a Tesla-style plug and the J1772 version has a J1772 plug. Match it to your car's charge port.

Which one do I need for a Tesla?

The NACS version — it has a native Tesla-style plug, so a Tesla or NACS-port car plugs in with no adapter. The J1772 version would need a J1772-to-NACS adapter for a Tesla.

Do they charge at the same speed?

Yes — both deliver up to 40 amps / 9.6 kW on a 240-volt outlet and drop to Level 1 on a 120-volt outlet. The connector does not change the charging speed.

What if I buy the wrong connector?

You would need an adapter to bridge the mismatch, which is an avoidable cost. Check your car's charge port first and buy the matching version. See our NACS vs J1772 guide if you are unsure which you have.
