Emporia vs Grizzl-E EV Chargers
Opposite philosophies, and a difference in amps. Emporia builds a connected charger that tells you what every session cost; Grizzl-E builds a sealed aluminum box with a DIP switch and nothing to update. Here's which one suits your garage.

Emporia and Grizzl-E are the two brands that dominate the “serious charger without premium pricing” conversation, and they get there from opposite directions. Emporia is a home-energy company that built a charger: connected, instrumented, and priced to undercut the big names. Grizzl-E — made by United Chargers — is a hardware company that builds cast-aluminum boxes designed to survive a Canadian winter with nothing to configure. This page compares the charger each brand points most buyers at — the Emporia Level 2 and the Grizzl-E Classic — and, more usefully, the two philosophies behind them.
The two, side by side

*Range figures are our arithmetic: rated amps × 240V, then divided by a reference efficiency of about 3.5 miles per kWh.
On speed, it depends how you install the Emporia
Hardwired, the Emporia delivers a full 48 amps and 11.5 kW — about 40 miles of range per hour at our reference 3.5 miles per kWh — on a 60-amp circuit, because the NEC sizes a continuous load at 125% of the current. The Grizzl-E Classic is a 40-amp charger: 9.6 kW, or about 34 miles per hour.
The gap closes the moment you plug the Emporia in rather than hardwiring it. On a NEMA 14-50 plug it is capped at 40 amps as well, because the 80% continuous-load rule caps any plug-in charger there. So the honest framing is this: if a 60-amp hardwired circuit is on the table, the Emporia is the faster charger by about six miles an hour. If it is not, these two charge at exactly the same rate. Work out which camp you are in with our panel capacity guide, and see 40 amps vs 48 amps for whether those six miles are worth the circuit.
The real split: information versus indifference
This is the comparison that matters, and it is not really about features. It is about what you want a charger to be.
Emporia wants to tell you things. The app schedules charging, reports what each session consumed, and estimates cost — which is genuinely valuable on a time-of-use tariff, where the difference between charging at 1am and 6pm can be most of your charging bill. It also makes the abstract concrete: instead of wondering what the EV is doing to your electricity bill, you can look. That lineage shows — Emporia sells home energy monitors, and the charger is part of that world.
Grizzl-E wants to be ignored. Amperage is set once with a physical switch. There is an LED. Grizzl-E’s own product data records the Classic’s smart function as “No Internet Connection”, so there is none: no account, no pairing, no firmware update that changes behavior, no WiFi dropout in a concrete garage. For a device that has to work every single night for a decade, “nothing to go wrong in software” is a real engineering position, not a cop-out.
The deciding question is therefore: will you actually use the data? If you are on a flat electricity rate and your car already schedules its own charging — nearly every modern EV does — then Emporia’s app is a feature you will check twice and forget. If you are on a time-of-use rate, share charging costs with someone, or simply like knowing, it earns its keep every month. We make that case in full in smart vs dumb chargers.
Build: where Grizzl-E pulls ahead
Both units publish the same temperature floor of -22°F, and both carry legitimate outdoor enclosure ratings — NEMA Type 4 protects against windblown dust, splashing and hose-directed water, which is a proper outdoor spec. The Grizzl-E adds IP67 sealing and a cast-aluminum housing, which is the more robust physical package: aluminum shrugs off impacts and UV in a way plastic does not, and it is the reason Grizzl-E units have the reputation they do.
The detail we think is genuinely underrated is the cable. Both give you 25 feet; Grizzl-E states in writing that the Classic’s output cable remains flexible in cold temperatures. In a real winter the charger does not stop working — the cable becomes a frozen hose you fight onto the holster. If your January mornings are genuinely cold, that is the difference you will notice most, and it is why a Grizzl-E holds the winter-build slot in our cold-weather picks.
One installation note from Grizzl-E’s own documentation, since it applies to both: where a GFCI breaker is required, Grizzl-E’s manual advises a 20 mA device because a 5 mA breaker may cause disruptions. Ground-fault protection is the most common source of nuisance tripping on EV circuits regardless of brand — we cover it in why chargers trip GFCI breakers.
Install flexibility: where Emporia pulls ahead
The Emporia’s dual-mode design is the most practically useful difference between these two chargers. Hardwire it for a full 48 amps, or plug it into a NEMA 14-50 for 40 — and change your mind later without buying anything. The Grizzl-E Classic has no hardwire upgrade path: it is a plug-in charger, and 40 amps is where it stays.
There is a receptacle catch worth knowing before you order, and it cuts the other way. Grizzl-E builds the Classic for either a NEMA 14-50 or a NEMA 6-50, and the SKU currently listed on Amazon is the NEMA 6-50 version — a three-prong 240-volt receptacle that is not the same as the 14-50 most EV owners have installed. If your outlet is a 14-50, that means a different SKU, and it is much cheaper to notice now than on install day. The Emporia’s plug-in mode uses a 14-50.
Both are plug-in units, so both come off the wall when you move — unless you hardwire the Emporia, in which case it becomes a fixture that stays with the house. If you rent, see our renter picks, and note that the outlet itself still needs a permitted install if one is not already there.
So which should you buy?
- Buy the Emporia if you want energy and cost data, you are on a time-of-use rate, you want a full 48 amps (or the option of it later), or you want the best value for a charger that lives in a garage.
- Buy the Grizzl-E Classic if the charger lives outside in a cold climate, you want the toughest physical build at this price, you actively don’t want a charger on your home network, and 40 amps is enough — which for most drivers it comfortably is. Check your receptacle is a NEMA 6-50 first.
A useful tiebreaker: think about year eight, not week one. If what worries you is a cloud service being discontinued or an app going unmaintained, Grizzl-E’s philosophy answers that. If what worries you is not knowing what the car costs to run, Emporia’s does. Both are honest answers to real concerns.
A note on the model this page used to compare. Grizzl-E’s 48-amp Ultimate 48A was discontinued in August 2026 and the brand moved that line to an 80-amp connected unit, so the Classic is now the Grizzl-E we put up against the Emporia. If you specifically want 48 amps with no app, the Lectron Nexus 48A is where we point people instead.

Frequently asked questions
Is Grizzl-E better than Emporia?
Neither is better in the abstract — they optimize for different things. Grizzl-E builds for physical durability and simplicity: cast aluminum, sealed enclosures, amperage set by a switch rather than software. Emporia builds for information and value: a real energy-monitoring app, ENERGY STAR, dual hardwired-or-plug-in installation, at a lower price. Cold and exposed favors Grizzl-E; data and flexibility favor Emporia.
Which charges faster, Emporia or Grizzl-E?
The Emporia, if you hardwire it. The Emporia Level 2 delivers 48 amps / 11.5 kW hardwired — about 40 miles of range per hour at a reference 3.5 miles per kWh — on a 60-amp circuit. The Grizzl-E Classic is a 40-amp plug-in charger: 9.6 kW, about 34 miles per hour. Plug the Emporia in instead of hardwiring it and the two tie at 40 amps, because that is the ceiling for any plug-in charger. Grizzl-E no longer sells a 48-amp model at all — the Ultimate 48A was discontinued in August 2026.
Does the Grizzl-E Classic have an app?
No, and Grizzl-E is unambiguous about it — its own product data records the Classic's smart function as 'No Internet Connection'. Amperage is set with a physical DIP switch and status is an LED. The brand sells separate connected editions (the Smart, the Classic Connect) if you want one. If you want scheduling and energy history from the charger itself, the Emporia is the clear pick of these two.
Which is better for cold weather?
Grizzl-E, by design and by a small margin on paper. Both publish an operating range down to -22F, but Grizzl-E's cast-aluminum, IP67-sealed build is the tougher physical package and the company states in writing that the Classic's 25 ft output cable remains flexible in cold temperatures — which is the complaint winter owners actually raise. The Emporia's NEMA 4 enclosure and identical temperature floor still make it a perfectly capable cold-climate charger.
Can either be plugged in instead of hardwired?
Both, in different directions. The Emporia can be hardwired at 48 amps or plugged into a NEMA 14-50 at 40. The Grizzl-E Classic is a plug-in unit — Grizzl-E builds this model for a NEMA 14-50 or a NEMA 6-50 receptacle, and the SKU currently listed on Amazon ends in a 6-50, so check which one you have. If you rent or want the charger to move with you, either works; if you want a full 48 amps, only the hardwired Emporia gets there.
Which one should I buy if I'm on a time-of-use electricity rate?
Either works, but the Emporia makes it easier. Its app schedules charging into the off-peak window and then shows you what each session consumed and cost, which turns the tariff from a theory into a number. With the Grizzl-E Classic you schedule in the car instead — nearly every modern EV can do this — and check consumption on your utility bill.
