Lectron NEXUS vs Grizzl-E Classic
The two serious chargers on this site with no app, no account and nothing to log into. One of them goes to 48 amps.

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.
Most of the charger market has decided you want an app. These two have not. The Grizzl-E Classic has been the no-software choice for years; the Lectron NEXUS is the newer one, and it is the only no-app unit here that reaches the 48-amp tier.

The 8 amps, and what they cost
Hardwired at 48 A, the NEXUS delivers about 11.5 kW against the Grizzl-E's 9.6 kW -- roughly six or seven more miles of range an hour. Getting them means a 60 A circuit and an electrician, because the 48 A version is hardwired.
The circuit each one needs
EV charging is a continuous load, so the circuit is rated at 125% of the charger
48 A x 1.25 = 60 A circuit for the hardwired NEXUS
40 A x 1.25 = 50 A circuit, which is what a NEMA 14-50 sits on
If your panel cannot spare 60 A, the 40 A units are the realistic tier
Cases: IP66 against cast aluminum
The Grizzl-E's cast-aluminum NEMA 4 / IP67 body is the more rugged object -- IP67 covers temporary immersion, which is more than a wall charger should ever meet. The NEXUS uses an IP66 automotive-grade housing, which covers powerful water jets. Both are fit for an exposed wall. Outdoor chargers has the whole field.
What you give up with no app
- Scheduled charging -- set it in the car instead. Nearly every EV can start charging at a chosen hour.
- Energy statistics -- a whole-home monitor does this better anyway.
- Firmware updates -- which is the point. Neither charger can be changed or broken from a server.
Which one to buy
| Your situation | Buy |
|---|---|
| A 60 A circuit is available and you want the speed | Lectron NEXUS, hardwired |
| You are plugging into an existing 14-50 | Either -- both charge at 40 A |
| You want a NACS cable with no adapter | Lectron NEXUS |
| You want the toughest enclosure | Grizzl-E Classic |
| You want to change amperage yourself later | Grizzl-E Classic, by switch |
The two units
No apps, no accounts. The NEXUS adds 8 amps if you hardwire it.
1. A long cable, no app
Lectron NEXUS Level 2 charger
Lectron · J1772 · 48 A / 11.5 kW · 23 ft cable

What is good
- 23 ft of cable, among the longest on this site
- 48 A hardwired, or 40 A from an existing NEMA 14-50
- ETL listed to UL 2594, UL 2231 and UL 2251 -- a listing, not a claim of compliance
- Wall mount, J-hook and plug holder included
What is not
- No app, Wi-Fi or scheduling on Lectron's NEXUS pages
- The 48 A version is hardwired only, so it needs an electrician and a 60 A circuit
- Lectron does not publish an operating temperature range for it

2. Harsh weather and no app

Grizzl-E Classic
United Chargers · J1772 · 40 A / 9.6 kW · 24 ft cable
A cast-aluminum box with no app, no account and no firmware to update. If you want a charger that behaves like an appliance, this is the one.

- Amperage is set with physical switches, not software
- Protections for over-current, over-voltage, ground fault and over-temperature
What is not
- 40 A ceiling, slower than the 48 A units if your panel can take more
- No scheduling, so off-peak charging has to be set in the car
- The cold-flexible 24 ft cable is only on the Extreme Edition
| Maximum output | 40 A / 9.6 kW at 240 V |
|---|---|
