Grizzl-E Mini vs Emporia Classic
Two good chargers that solve different problems. One question about your electricity bill decides which is right.

Picks are chosen from published specifications rather than hands-on testing; the method is written down so you can check it.
Ask one question: does your electricity cost the same at every hour of the day? If it does, buy the Grizzl-E Mini — scheduling saves you nothing and the adjustment range is worth real money. If it does not, the Emporia's scheduling pays for itself over a lease and the decision flips.
That is genuinely the whole comparison. Both are plug-in, both are safety-listed, both deliver 9.6 kW on a NEMA 14-50, and both come off the wall when you move. They differ in what they add on top.
Side by side
| Grizzl-E Mini Connect | Emporia Classic (NEMA 14-50) | |
|---|---|---|
| Maximum on a plug | 9.6 kW (40A) | 9.6 kW (40A) |
| Adjustable current | Yes — 7A to 40A | Not the headline feature |
| Fits a 30A dryer circuit | Yes, set to 24A | Not its intended use |
| Scheduling / off-peak | Not the headline feature | Yes, through the app |
| Energy reporting | — | Yes, real-time charge rate |
| Cable length | 25 ft | Shorter than the Grizzl-E |
| Enclosure | UL Type 4 / IP67 | Type 4, watertight |
| Connector options | J1772 or NACS | J1772 or NACS |
| Needs Wi-Fi to be useful | No | Yes, for the features you paid for |
Note the last row, because it catches people out. The Emporia's advantages live in an app, and an app needs a network. A detached carport or a below-grade parking structure frequently has no usable Wi-Fi, and in that spot you have bought a smart charger and got a plain one.

#1 · Not knowing your outlet yet
Grizzl-E Mini Connect Portable Charger
Adjustable from 7 to 40 amps and shipped with four plug adapters, which is the closest thing to a unit that fits whatever outlet you turn out to have.
| Adjustable current | 7A to 40A (9.6 kW maximum)source |
|---|---|
| Voltage | Automatically detects 120V (Level 1) or 240V (Level 2)source |
| Cable length | 25 ft (7.6 m)source |
| Plug and adapters | NEMA 14-50 plug plus four included electrical adapterssource |
| Connector | J1772 or Tesla (NACS) versionssource |
| Enclosure | UL Type 4 / IP67 ratedsource |
| Certification | UL tested and certified, Energy Star certifiedsource |
What those numbers mean
The adjustable current is the feature that matters to a renter, and it is not a convenience. A 30 amp dryer circuit legally supports 24 amps of continuous EV load; a unit that can be set to 24 amps can use that circuit, and a fixed 40 amp unit cannot.
25 ft of cable is nine feet more than the common 16 ft, and nine feet is frequently the difference between reaching the car and not.
IP67 and a UL Type 4 enclosure describe the unit's own weather tolerance. They say nothing about the outlet it plugs into, which is usually the part that is not weather-rated.
What it does well
- 7-40A adjustment means one unit fits a 15, 20, 30 or 50 amp circuit
- 25 ft cable is among the longest on a portable unit
- Four plug adapters included, so an outlet change does not mean a new charger
- Available with either a J1772 or a NACS connector
What it does not
- Costs meaningfully more than a fixed-amperage unit that does one job
- The bundled adapters make it easy to plug into a circuit you have not actually checked
Skip this one if: You know exactly which outlet you have, it is not changing, and you would rather put the money into a longer cable than into adjustability you will set once and never touch.

#2 · Charging on a schedule
Emporia Classic Level 2 EV Charger (NEMA 14-50 plug)
A plug-in smart charger whose scheduling genuinely pays for itself if your utility bills you differently overnight.
| Maximum output | 9.6 kW (40A) with a NEMA 14-50 outlet; 11.5 kW (48A) hardwiredsource |
|---|---|
| Connector | J1772 or NACS (Tesla) modelssource |
| Enclosure | Type 4 enclosure, watertight, indoor or outdoorsource |
| Certification | UL certified and GFCI protectedsource |
| Scheduling | Off-peak scheduling and real-time charge-rate monitoring in the Emporia appsource |
What those numbers mean
Note the honest asymmetry in the first row: the 48 amp headline number is the hardwired figure. On a NEMA 14-50 plug — the only version a renter should be looking at — it is a 40 amp charger. That is not a downgrade, it is what the plug is rated for.
The scheduling is the actual reason to pay more here. If you are on a time-of-use rate, charging on a timer is worth real money over the length of a lease.
It is a wall-mount form factor with a plug on it. You can hang it on a hook or leave it in the trunk; nothing about it requires a bracket screwed into the landlord's drywall.
What it does well
- Scheduling and energy monitoring that are useful rather than decorative
- Type 4 watertight enclosure rated for outdoor use
- Sold with either a J1772 or a NACS connector
- The plug-in version needs no electrician and comes off the wall when you move
What it does not
- The advertised 48 amps is hardwired-only; the plug-in version is 40 amps
- Scheduling needs Wi-Fi, which is not a given in a detached carport or a parking structure
Skip this one if: Your electricity costs the same at every hour and there is no Wi-Fi where you park. You would be paying for a feature set you cannot reach or use.
Buy the Grizzl-E Mini if...
- Your outlet is a 30 amp dryer or laundry circuit. The adjustment down to 24A is the only thing that makes that circuit usable, and it is decisive.
- You do not know your outlet yet, or you may move during the life of the purchase.
- Your parking is more than a few feet from the receptacle — 25 ft of cable is the longest here.
- Your electricity costs the same all day. Then scheduling is a feature you would configure once and forget.
- There is no Wi-Fi where you park.
Buy the Emporia Classic if...
- You are on a time-of-use tariff. Charging inside a cheap overnight window is worth real money over a lease, and doing it on a timer rather than by remembering is the entire point.
- You want to see what charging actually costs you — the energy reporting turns the cost arithmetic into a measured number rather than an estimate.
- Your outlet is a confirmed NEMA 14-50 that is not going to change.
- There is usable Wi-Fi where you park.
The specification that trips people up on the Emporia
What they have in common, and why it matters
Both plug in. Neither needs an electrician, a permit or a landlord's approval to use an outlet that already exists, and both unplug and leave with you. In a category where most "best charger" lists are dominated by hardwired wall units, that shared property is more important than anything separating the two.
Both are also offered with either a J1772 or a NACS connector, so neither forces an adapter into the chain. If your household has cars with different inlets, that is a reason to buy the J1772 version plus one adapter rather than committing the charger to one connector.
The honest verdict
For the specific reader this site is written for — somebody without a garage, frequently working with a shared or borrowed outlet whose rating they had to go and check — the Grizzl-E Mini is the safer purchase, because the adjustment range covers the case where the outlet turns out to be smaller than hoped. The Emporia is the better purchase for a confirmed 50 amp circuit on a tariff that rewards charging at 2am.
Neither is a mistake. The mistake is buying the scheduling and discovering there is no Wi-Fi, or buying the fixed unit and discovering the outlet is 30 amps.
What we could not compare
Build quality, app reliability, cable behavior in cold weather and long-term durability — all of which need hardware we do not have. This comparison is drawn from both manufacturers' published specifications, cited on each product below. We have not handled either unit and do not claim to have. The method sets out what that does and does not let us tell you.
Questions people actually ask
Which is better, Grizzl-E Mini or Emporia?
Grizzl-E Mini if your outlet is unconfirmed or a 30 amp dryer circuit, or if your electricity costs the same all day. Emporia if you are on a time-of-use tariff with a confirmed NEMA 14-50 and there is Wi-Fi where you park.
Do both charge at the same speed?
On a NEMA 14-50 plug, yes — both deliver up to 9.6 kW at 40 amps. Emporia's advertised 11.5 kW applies to its hardwired configuration, which is not a renter option.
Can the Emporia run on a dryer outlet?
That is not its intended use. Sharing a 30 amp circuit needs a charger that can be set to 24 amps, which is the Grizzl-E Mini's defining feature and the main reason to choose it.
Is the Emporia app worth paying for?
On a time-of-use electricity rate, yes — charging inside the cheap window on a timer is worth real money over a lease. On a flat rate it saves nothing, and it needs Wi-Fi where you park to work at all.
Do either of them come with a Tesla connector?
Both are offered in J1772 and NACS (Tesla) versions, so you can match your car's inlet directly rather than adding an adapter to the chain.
