EVIQO 40A Plug-In Charger Review

The most charger you can get without an electrician's invoice: EVIQO's hardwired 48-amp unit, rebuilt around a NEMA 14-50 plug, with the app, the cable and the certifications intact.

By Stephen V.Last updated How we pick

Most of the value in a home charger is decided before you choose a brand, by a single question: plug in, or hardwire?Hardwiring buys you 48 amps and a tidier installation. Plugging in caps you at 40 amps but can turn a thousand-dollar electrical job into a fifteen-minute one — if a suitable receptacle already exists — and lets you take the charger with you when you move.

The EVIQO 40A is what happens when a manufacturer takes a genuinely good hardwired charger and answers that question the other way. You keep the 25-foot cable and the 40-inch input lead that give EVIQO the longest total reach in its class, the IP66 / NEMA 4 enclosure, the WiFi app, and the UL, ETL, FCC and ENERGY STARlistings. What you give up is eight amps — and what you gain, beyond the install saving, is an unusually wide 6 to 40 amp adjustment range. Here is the full picture.

EVIQO 40A NEMA 14-50 Charger

The most charger you can get without an electrician's invoice. It plugs into a NEMA 14-50 outlet for a full 40 amps, keeps the WiFi app, the ENERGY STAR listing and the 25 ft cable from EVIQO's hardwired unit, and can be unplugged and taken with you when you move.

Strengths

  • Plugs into an existing NEMA 14-50 outlet — no hardwiring, and it comes with you
  • Real WiFi app with 6-40A adjustment, scheduling and energy tracking
  • 25 ft charging cable plus a 40 in input lead, in an IP66 / NEMA 4 body

Trade-offs

  • 40 amps is the plug-in ceiling — for 48A you need the hardwired version
  • Needs a proper EV-grade 14-50 receptacle (an old dryer outlet is not the same thing)
  • Smaller brand with a shorter track record than ChargePoint or Wallbox

Our charging-speed math. At 40A (9.6 kW) and ~3.5 miles per kWh it adds roughly 34 miles of range per hour — an overnight charge for almost any daily commute.

Build note. Plug-in Gen-2 unit: 25 ft charging cable plus a 40 in NEMA 14-50 input lead, with app-adjustable output from 6 to 40 amps.

Specs read from the manufacturer spec sheet, on August 11, 2026. “Not published” means the brand does not state that figure.

The plug is the product

EVIQO sells this unit and its hardwired sibling as effectively the same charger with a different tail, and that is a fair description. The specification that changes everything is the NEMA 14-50 plug, and it changes three things at once:

  • The install.With a suitable receptacle already present, mounting this charger is a homeowner job. Without one, you still need an electrician — but you need them for a receptacle, not for a hardwired termination inside a manufacturer-specific enclosure.
  • The ceiling.A NEMA 14-50 sits on a 50-amp circuit, and the continuous-load rule caps a 50-amp circuit at 40 amps of charging. That is why no plug-in charger delivers 48 amps — it is a code constraint, not a manufacturer’s choice.
  • The ownership. A plug-in charger is portable property. It comes off the wall, goes in a box, and moves house with you. A hardwired charger is a fixture and generally stays.

For renters, that last point is decisive, and we cover the whole case in our renter roundup. For owners, it is a smaller consideration than the install saving — see hardwired vs plug-in for the full comparison.

Reach: the spec EVIQO actually wins on

The reason we rate EVIQO above several better-known brands has nothing to do with amps. It is 25 feet of charging cable plus a 40-inch input lead, which is the longest combined span in this class. The input cable is the underrated half: it means the charger body does not have to be mounted directly at the receptacle, so you can put the box where it is convenient to reach the car and still plug into an outlet three feet away.

In a two-bay garage, or where the receptacle is in an awkward corner because that is where the panel happened to be, that flexibility is worth more than eight amps ever will be. Our long-cable rounduphas the measuring method — do it before you buy, and never solve a reach problem with an extension cord.

The 6-to-40-amp range, and why it matters more than it sounds

EVIQO publishes an app-adjustable output from 6 to 40 amps. Most chargers bottom out at 16. That low floor turns this unit into a solution for two situations most reviews never mention:

A circuit smaller than 50 amps.Under the NEC’s continuous-load rule you take the breaker rating and multiply by 0.8: a 40-amp circuit supports 32 amps, a 30-amp circuit supports 24, a 20-amp circuit supports 16. A charger that can be set that low can live on circuits a fixed 40-amp unit cannot legally use. If your panel is the constraint, this is exactly the flexibility you want — see our small-panel roundup and the wire and breaker guide.

A car that cannot use 40 amps. Plug-in hybrids in particular have much smaller onboard chargers, and there is no point installing capacity the vehicle will never draw. Setting the charger to match the car lets you install a smaller, cheaper circuit deliberately rather than by accident. Our PHEV roundup works that through.

Build, weather and certifications

The enclosure is published as IP66 / NEMA 4. Reading that precisely: under IEC 60529 a first numeral of 6 means dust-tight and a second numeral of 6 means protected against powerful water jets, while NEMA Type 4 covers windblown dust, splashing water and hose-directed water. Both are strong ratings for a wall-mounted charger, and either would be sufficient for a sheltered outdoor install.

One caveat we always flag on plug-in units going outdoors: the charger’s own rating does not extend to the receptacle it plugs into. An outdoor 14-50 needs a weatherproof in-use enclosure and correctly specified ground-fault protection upstream, and getting that wrong is the most common cause of the nuisance tripping we cover in why chargers trip GFCI breakers.

On paperwork, EVIQO publishes UL, ETL, FCC and ENERGY STARlistings and a three-year standard warranty. That is a more complete set than several better-known brands manage, and the ENERGY STAR certification specifically is what many utility rebate programs ask for — see our ENERGY STAR roundup and incentives guide.

Charging speed, worked out

At 40 amps and 240 volts this unit delivers 9.6 kW. At our standard reference of about 3.5 miles of range per kWh, that is roughly 34 miles of range per hour— about 340 miles across a ten-hour night. The hardwired 48-amp version delivers 11.5 kW, or about 40 miles per hour.

The step between them is six miles of range per hour. If you drive 40 miles a day, the 40-amp unit replaces that in about 70 minutes and the 48-amp unit in about 60. Both finish long before you wake up. The 48-amp version earns its keep for drivers covering serious daily distance, households sharing one charger between two cars, or anyone who genuinely needs a fast mid-day top-up — the case is made in 40 amps vs 48 amps.

Who should buy it — and who should skip it

Buy itif there is already a NEMA 14-50 receptacle in your garage, or if adding one is cheaper for you than a hardwired run. Buy it if you rent, or expect to move, and want a charger that comes with you. Buy it if your panel is tight and the 6–40 amp range is the thing that makes a charger fit at all. And buy it if cable reach is your binding constraint, because nothing else at this price gets a 25-foot cable and a 40-inch input lead into the same box.

Skip itif you want the maximum speed a home circuit can deliver — that is the hardwired EVIQO 48A or another 48-amp unit on a 60-amp circuit. Skip it if you want the most polished app and the deepest support organization, where ChargePoint is still ahead. And skip it if you want the toughest possible enclosure for a fully exposed wall, where the NEMA 4X Autel MaxiCharger is better armored. For most homes with an existing outlet, though, this is the charger that gets you 90% of the result for a fraction of the installation.

Frequently asked questions

What is the difference between the EVIQO 40A and the EVIQO 48A?

The install method and eight amps. The 48A is hardwired to a 60-amp circuit and delivers 11.5 kW, about 40 miles of range per hour; the 40A plugs into a NEMA 14-50 receptacle on a 50-amp circuit and delivers 9.6 kW, about 34 miles per hour. Both share the 25-foot cable, the 40-inch input lead, the IP66/NEMA 4 body, the app and the UL/ETL/FCC/ENERGY STAR listings. If you already have a 14-50 outlet, the 40A is the far cheaper route to almost the same charging.

Can I plug the EVIQO 40A into a dryer outlet?

Not without checking, and usually not directly. EVIQO's own product page notes that the unit needs a proper EV-grade four-prong NEMA 14-50 receptacle rather than a dryer outlet — a typical dryer receptacle is a NEMA 14-30 on a 30-amp circuit, which is a different plug on a smaller circuit. Under the continuous-load rule a 30-amp circuit supports at most 24 amps of charging, so even where an adapter exists the charger must be limited accordingly. Have an electrician confirm the circuit before you plug anything in.

How low can the EVIQO 40A be set?

EVIQO publishes an app-adjustable output range of 6 to 40 amps, which is an unusually low floor — most chargers stop at 16. That matters if your circuit is smaller than 50 amps, or if you are sharing capacity with other large loads: you can set the charger to whatever the circuit safely supports rather than buying a different unit. It also makes this a sensible charger for a plug-in hybrid whose onboard charger cannot use 40 amps anyway.

Is the EVIQO 40A rated for outdoor use?

EVIQO publishes an IP66 / NEMA 4 rating for the enclosure. In IEC terms, a first numeral of 6 means dust-tight and a second numeral of 6 means protected against powerful water jets; NEMA Type 4 covers windblown dust, splashing and hose-directed water. That is a genuinely strong rating for a wall unit. Note that the plug and receptacle are a separate question from the charger body — an outdoor plug-in installation needs a weatherproof receptacle enclosure and the correct GFCI protection upstream.

How fast does a 40-amp charger actually charge?

At 40 amps and 240 volts you get 9.6 kW, which at our reference of about 3.5 miles per kWh is roughly 34 miles of range per hour. Across a ten-hour overnight window that is around 340 miles — more than almost any daily driver needs replaced. The step up to 48 amps adds about six miles per hour, which across a night is usually invisible. This is why the plug-in ceiling is far less of a compromise than the spec sheet suggests.

Does the EVIQO 40A need an electrician?

Not if a correctly rated NEMA 14-50 receptacle already exists and is in good condition — then it is a matter of mounting the unit and plugging it in. If the receptacle needs to be installed, that is a 240-volt circuit and a permitted job in most jurisdictions, so yes. The saving over a hardwired unit is real but it is a saving on the charger end of the job, not on the circuit.
