This comparison puts six portable Level 1 and Level 2 chargers from ELEGRP and Lectron side by side on manufacturer specifications: current, voltage, wall plug, cable length, connector, listed certification and listed IP rating. Our videos record use of an ELEGRP 40A NACS charger with a Tesla Model Y, but we have not established that the filmed unit is the exact model or hardware revision sold in the linked listing. We have not used the other five listed units. The order is by maker and level, not a ranking or a claim that these are the best chargers. Check the exact model against its current manufacturer documentation and ask a licensed electrician about the circuit.

How to choose
Level 1 or Level 2
A Level 1 charger runs from a 120 V household outlet; the Lectron Level 1 unit here lists 12 A at 120 V, about 1.44 kW. A Level 2 charger runs from 240 V; the 40 A units here list 9.6 kW, roughly six and a half times as much at full current. How much range that adds per hour depends on the car, and the car can cap the rate: our first recorded session initially showed 32 A and later 40 A. Those are readings spoken by the owner, not independently logged measurements. ELEGRP's 16A unit does either, with a 240 V plug and an adapter for a 120 V outlet.
J1772 or NACS
Pick the connector your car's charge port takes. J1772 is the connector most non-Tesla EVs in North America have used. NACS is the connector Tesla uses, standardized as SAE J3400, and some other makers' newer cars use it too. The J1772 chargers here say a Tesla needs an adapter; we did not test any adapter. The ELEGRP 40A NACS unit is the one we connected to our Tesla Model Y without an adapter.
Plug and outlet
Each of these chargers has a fixed wall plug. NEMA 5-15 is the ordinary 120 V household outlet, NEMA 6-20 is a 240 V 20 A outlet, and NEMA 14-50 is the 240 V 50 A outlet often used for RVs and electric ranges. The plug has to match an outlet you already have or one a licensed electrician installs. We do not cover plug adapters between outlet types.
Manufacturer circuit requirements
ELEGRP's page for its 40 A NACS charger specifies a properly installed 240 V outlet on a dedicated 50 A circuit. That is the manufacturer's requirement for that product, not a determination that any existing outlet or wiring is suitable. Other models and settings have their own requirements. Have a licensed electrician check the exact charger, wiring, breaker and outlet against the manufacturer's current instructions and applicable local code; this comparison does not size circuits or provide installation instructions.
Cable length, weather rating and certification
The Lectron units here list 16 ft cables and the ELEGRP units here list 25 ft. Check the manufacturer's reach and cable-use instructions for the exact variant. IP ratings describe specified dust and water test conditions; do not assume a larger number makes a charger suitable for every kind of weather or water exposure. Some makers rate the control box and connector separately or use a NEMA enclosure type instead. We reproduce their stated ratings and disagreements below without treating the scales as interchangeable. UL and ETL wording is attributed to the maker; we did not independently verify any certificate or listing.
The chargers
ELEGRP 40A Level 2 NACS (Tesla) portable charger
Related to the ELEGRP charger in our videos; an exact match to this listing is not established. In those videos the owner charges a Tesla Model Y without an adapter, and the charger screen shows 40 A, which he reads as about 9.5 kW at about 237 V; after a few weeks of daily charging he says it had been fine. That is one unit over a short period. It has no app that he found, the maker lists a 1 to 12 hour delay timer, and he found the plastic wall cradle flimsy. ELEGRP's page says 40 A charging requires a properly installed 240 V outlet on a dedicated 50 A circuit. The model string read in the video is not on the store page, so we cannot confirm it is the same hardware revision. (video)

ELEGRP 40A Level 2 J1772 portable charger
ELEGRP's J1772 version of its 40 A portable charger, for cars with a J1772 port; the maker's page says Tesla vehicles need a NACS adapter, sold separately. The maker lists 9.6 kW at 40 A, five current settings and a 1 to 12 hour delay timer, and also sells 16 ft and 21 ft versions. The Amazon link is the 25 ft NEMA 14-50 version. We have not used this unit.

ELEGRP 16A Level 1 and Level 2 J1772 portable charger
A lower power unit that runs on either voltage: the maker lists up to 3.84 kW on 240 V through its NEMA 6-20 plug and 1.44 kW on 120 V through the included NEMA 5-15 adapter. Its page lists no delay timer, says Tesla owners need an adapter, sold separately, and gives IP67 in one place and IP66 in another; ELEGRP's manual lists a Type 4 enclosure and no IP figure, so it does not settle which, and we show both. We have not used this unit.

Lectron 40A Level 2 J1772 portable charger
Lectron lists 9.6 kW at 40 A and sells this charger with or without WiFi app control; the Amazon link is the version whose listing names no app. The listing says it is not natively compatible with a Tesla without an adapter. We have not used this unit.

Lectron 12A Level 1 J1772 portable charger, WiFi version
The only Level 1 only charger here: it plugs into an ordinary household outlet, and the maker lists 1.44 kW. Lectron's product page gives IP65 for the control box in one place and IP67 in its FAQ; the specifications table in Lectron's manual lists IP67 or Type 6, so we use that. We have not used this unit.

- ELEGRP's user manual for the 16A J1772 Level 1-2 charger, linked from that store page (retrieved 2026-10-27), lists model ECP24-16F0-01, 16 A, 120 V/240 V, a NEMA 6-20P plug, a 25 ft length and enclosure Type 4. It gives no IP figure, so it does not settle the page's IP67 and IP66; we show both. (store.elegrp.com)
- Lectron's product page for its 40A Level 2 J1772 charger (retrieved 2026-10-26) lists 40A, 240V and 9.6 kW and 'UL2594 / UL2231 Certified', and says the charger handle is UL 2251 certified and the charger is Energy Star, ETL and FCC certified. (ev-lectron.com)
- Lectron's user manual for the 40A J1772 charger without app control, model LECHG14-50-40ABLKUS (file v25, retrieved 2026-10-27), lists control-box water resistance IP65 and charging handle water resistance Type 4, with UL2594, UL2251, SAE J1772 and UL2231 as reference standards. Lectron's manual for the WiFi version of this charger lists the handle as Type 3R; the Amazon link here is the version whose listing names no app. (ev-lectron.com)
- Lectron's product page for its 40A Level 2 Tesla (NACS) charger (retrieved 2026-10-26) lists the same 40A, 240V, 9.6 kW and certification wording, and says app control is on the WiFi version only. An image on the page labels the control box IP65 and the handle IP54. (ev-lectron.com)
- Lectron's user manual for the 40A Tesla (NACS) charger with app control, model LECHG14-50-40ATSLBLKUS-APP (retrieved 2026-10-27), lists control-box water resistance IP65 and charging handle water resistance Type 3R. Where the product page image says IP54 for the handle, we use the manual's Type 3R. (ev-lectron.com)
- Lectron's product page for its Level 1 J1772 WiFi charger (retrieved 2026-10-26) lists 12 A, 120 V and 1.44 kW, a NEMA 5-15 plug, a 16 ft cord and 'UL2594 / UL2231 Certified'. It calls the control box IP65-rated in its description and IP67 in its FAQ. (ev-lectron.com)
- Lectron's user manual for the Level 1 J1772 WiFi charger, model LECHG5-15-12ABLKUS-APP (file v14, retrieved 2026-10-27), lists in its specifications table control-box water resistance 'IP67 or Type 6' and charging handle water resistance Type 3R. We use that over the product page's IP65; a badge graphic elsewhere in the manual reads IP65 tested. (ev-lectron.com)
What happened to us
- The owner connected the ELEGRP 40A NACS charger to his Tesla Model Y without an adapter. On the first session the current rose to 32 A and stayed there; later the charger screen showed 40 A, which he reads as about 9.5 kW at about 237 V split phase. These are figures read aloud from the screen, not logged data. (video)
- In a short, the owner shows the charging limit at 32 A, sets it to 40, and the charger then reads 40 A, which he reads as about 9.5 kW at 237 V split phase. The short does not show where the limit was set beyond the screen in view. (video)
- In another short, the owner says the portable charger he uses sits between his other chargers on current, more than 32 A but less than 48 A, can be used mobile or mounted, has no app that he found, and runs only on 240 V split phase through its plug, so it is not meant to be hardwired. He says it has worked fine. (video)
- The owner describes the ELEGRP wall cradle as all plastic, with the plug hanging from a single edge. In a spoken update a couple of weeks later, and in a follow-up, he says the charger had been fine with daily charging over a few weeks; that is his account, with no logs. (video)
What we did not verify
- Our videos cover one ELEGRP 40A NACS charger over a few weeks. We have not established that it is the exact model or hardware revision in the linked listing. We have not used the other five listed units; their coverage is based on published manufacturer information.
- Specs are copied from each maker's product page as retrieved on 2026-10-26. Water ratings are the maker's own: for the three Lectron units and the ELEGRP 16A we read the maker's user manual on 2026-10-27, and where a Lectron page and its manual disagree we use the manual. We never use an Amazon listing's rating. Maker pages and manuals change; check them before you buy.
- Certification wording is the maker's. We did not look up any certificate or listing.
- We did not establish that the ELEGRP unit in our videos is the same hardware revision as the product on ELEGRP's page or the Amazon listing; the model string read in the video is not on the page. The shorts do not name the charger's brand.
- Nothing here sizes a circuit or says an outlet, breaker or vehicle is suitable. The manufacturer circuit requirement quoted above is not an assessment of any installation.
- The list covers two makers only and is not a ranking. We print no prices because they change; the Check price buttons open the current Amazon listing.
Questions and answers
What is the difference between a Level 1 and a Level 2 EV charger?
Level 1 runs from a 120 V household outlet and the unit here lists about 1.44 kW. Level 2 runs from 240 V; the 40 A units here list 9.6 kW. The car can cap either rate.
Will a J1772 charger work with a Tesla?
The J1772 makers here say a Tesla needs an adapter. We did not test an adapter; the NACS units plug straight into a Tesla, and we charged our Model Y with the ELEGRP NACS unit that way.
What outlet does a 40 A portable charger need?
The 40 A units here use a NEMA 14-50 plug, and ELEGRP's page says 40 A charging requires a properly installed 240 V outlet on a dedicated 50 A circuit. Ask a licensed electrician about your wiring.
Why are there no prices on this page?
Amazon prices change often, so we do not print them. The Check price buttons open the current Amazon listing, and we earn a commission on qualifying purchases.
Did you test all of these chargers?
No. Our videos show use of an ELEGRP 40A NACS charger, but we have not confirmed an exact match to the linked listing. The other five entries use manufacturer specifications; this is not a comparative hands-on test.
