The comparison, on published figures only
| Charger | Max current | Enclosure | Published temp range | ENERGY STAR | Warranty |
|---|
| Grizzl-E Classic Connect | 40 A (plug-in) | UL Type 4, cast aluminum | −22 to 122°F | Not published | 3 or 5 years (option) |
| Autel MaxiCharger | 50 A (hardwired) | IP65 / NEMA 4X | −40 to 131°F | Yes | 3 years |
| EVIQO 48A | 48 A (hardwired) | IP66 / NEMA 4 | −22 to 122°F | Yes | 3 years |
| ELEGRP 40A | 40 A (plug-in) | IP67 station | Stated −21°F floor | Not on the certified list | Up to 2 years |
| Emporia Level 2 | 48 A (either way) | Outdoor rated | Not published | Yes | 3 years |
| Lectron NEXUS J1772 | 48 A (hardwired) | IP66 | Not published | Yes | 3 years |
Read that table and one pattern dominates: the Grizzl-E’s advantages are the enclosure and the warranty option, and the alternatives’ advantages are amps and ENERGY STAR. The Autel is the only charger that beats it on its own ground, with a published envelope 18 degrees colder at the bottom and 9 degrees hotter at the top. The ELEGRP publishes an IP67 station rating, which sounds higher than UL Type 4 — worth noting that ELEGRP publishes IP54 for the connector on the same product, so station and connector ratings are not interchangeable.
Match the alternative to your actual reason
“I wanted something that survives a driveway.”The Autel. It is the toughest published envelope on this site and the enclosure is the reason to buy it. Accept the 70-amp circuit its 50-amp output requires, or turn it down — Autel publishes 16 to 50 amps adjustable. Our outdoor and cold-weather picks rank the whole field on exactly this criterion, and Autel versus Grizzl-E is the head-to-head.
“My utility rebate needs ENERGY STAR.”The EVIQO 48A, which also gets you eight more amps and the longest total reach here — a 25-foot cable plus a 40-inch input lead — with current adjustable from 6 to 48 amps in one-amp steps. See EVIQO versus Grizzl-E, which argues that the real choice between them is a choice of circuit rather than of eight amps, and our ENERGY STAR picks.
“It is more charger than I need.”The ELEGRP. Same 40-amp plug-in format, five current levels you set on the unit with no app, and the cheapest real 40 amps in this registry. What you give up is the metal case, the warranty length and the app entirely — ELEGRP versus Lectron 40A compares it with the other budget option, and our plug-in picks put it in context.
“I want to know what charging costs me.” The Emporia Level 2, which installs hardwired or on a 14-50 plug, publishes 48 amps and ENERGY STAR, and whose app is part of a whole-home energy platform rather than just a charger controller. See Emporia versus Grizzl-E and reading a charger’s energy data.
“I do not want an app at all.”The Lectron NEXUS J1772 — 48 hardwired amps with no radio, which the ENERGY STAR certified list records precisely: the NEXUS appears twice, at 1.86 W standby without a radio and 3.02 W with one. The trade is stated plainly in our registry entry: Lectron publishes no adjustable current range for this model, so it needs a 60-amp circuit to be used at all. See our no-Wi-Fi picks.
Alternatives inside the Grizzl-E line
Worth knowing before you leave the brand, because two of them may be what you actually wanted:
The Grizzl-E Miniis the same company’s compact portable — a published 6.9 by 3.1 by 2.4 inch body weighing 9.8 pounds, a 14-50 plug with four outlet adapters in the box, and a hardware DIP switch capping current at 40, 32, 24 or 16 amps. If your issue with the Classic was size or outlet flexibility, it is the answer; see Mini versus Classic.
The Grizzl-E Ultimate 48A is the hardwired 48-amp step up, with OCPP on top of the Grizzl-E app. Its catch is the one we repeat everywhere: the only child listing Amazon carries is the NACS output-cable version, which for a J1772 car means a permanent adapter. See Classic versus Ultimate.
And one note on the whole category: the Grizzl-E ranks first on our most reliable chargers page, and the reason is relevant here. No manufacturer or certifier publishes failure-rate data for residential charging equipment, so that page ranks the four facts brands can be held to — enclosure rating, temperature range, how specifically the certification is stated, and warranty term. Grizzl-E wins on three of the four. If reliability was your reason for looking at it, an alternative needs to beat it on those, and only the Autel does.
