Wallbox Pulsar Plus vs Grizzl-E

Put the two datasheets side by side and these look like the same charger. Forty-eight amps. Eleven and a half kilowatts. A twenty-five-foot cable. Hardwired. Rated NEMA Type 4 for indoor and outdoor installation. Both now publish OCPP, which makes them the only two brands in our registry that do.

Then you look at the physical figures. Wallbox publishes 4.4 pounds. Grizzl-E publishes 24.25. These are not variations on one design; they are two different answers to the question of what a wall charger is. One is a compact plastic-bodied smart device that happens to pass 240 volts. The other is a cast-aluminum box from Canada with a wider temperature range than almost anything else in the category.

Which is right for you comes down to four published differences, and — unusually for a comparison on this site — price is not one of them. Both land in the upper half of the market, with the Wallbox the dearer of the two.

Three notes on that table. The 11.5 kW on the Grizzl-E column is our arithmetic (48 × 240), because Grizzl-E publishes amps rather than kW; Wallbox publishes the kW itself. The Ultimate’s blank warranty cell is deliberate — Grizzl-E offers a “3 Year” or “5 Year” selector at checkout without stating what either term covers, and a selector is not a published warranty. And the WiFi row on the Ultimate reads from our earlier reading of Grizzl-E’s spec page; the section below explains why, and why it has changed.

1. Four pounds against twenty-four, and where each one can go

The Wallbox is the smallest 48-amp charger we track by a wide margin. Its own datasheet publishes 7.8 x 7.9 x 3.9 inches and 4.4 pounds without the cable. That is light enough to hang off drywall between studs without blocking, small enough to fit beside a panel in a utility closet, and — this is the one people underestimate — unobtrusive enough on the front of a house that you will not resent looking at it.

The Grizzl-E Ultimate is built like an electrical enclosure, because it is one. Aluminum, made in Canada, 24.25 pounds, with Grizzl-E publishing a -30C to +50C operating range off the back of that mass. Twenty-four pounds wants masonry, a stud, or a proper post, and it wants the mounting cradle Grizzl-E ships with it. On a driveway pedestal in a snow state, that is exactly the charger you want. On a rented garage wall you may have to patch, it is not.

2. The temperature ceiling, which is the real decider

This is the figure neither brand advertises and the one we would make the decision on.

Wallbox publishes an operating temperature range of -22F to 104F. Grizzl-E publishes -22F to 122F.They are level at the cold end. They are eighteen degrees apart at the hot end, and 104F is not a high bar. An uninsulated garage with a west-facing wall, or an exterior wall in Phoenix, Las Vegas or inland California, spends part of every summer above it. A charger operated outside its published range is not guaranteed to fail, but it is operating outside what the maker will stand behind — which is exactly the kind of thing that matters when you are three years in and making a warranty claim.

Note what each claim is, too. Both are published operating ranges rather than tested ranges, which makes them directly comparable — unlike some brands in this category, which publish a range the unit was “tested” to and leave you to infer the rest. Our cold-weather roundup ranks the whole field on this basis, and the ratings guideexplains why we will not convert Grizzl-E’s UL Type 4 into an IP number to make the comparison tidier.

3. Load management, and the panel upgrade it can avoid

If your panel is full, this section is worth more than everything else on the page.

Wallbox publishes Static Load Management and Dynamic Load Management on its North America datasheet, with current adjustable by a hardware selector from 16 amps and in software from 6, and optional dynamic adjustment by an energy-management system. In plain terms: the charger can watch what the rest of the house is drawing and back off, instead of tripping the main breaker. That is the feature that lets a 48-amp charger live on a panel that could not otherwise host one, and it is routinely cheaper than upgrading the service.

Read the footnote, though. Wallbox marks load management, solar charging and schedule planning with “May require power meter accessory” and states on its US product page that solar charging is not compatible with multi-charger installations or with OCPP. The accessory is a separate purchase. Our load-management guide works through which of these features need a second device.

Grizzl-E publishes no load management for the Ultimate. What it publishes instead is participation in utility Demand/Response programsthrough the Grizzl-E Connect app — which is a different thing entirely, and in some service territories a more lucrative one. Demand response shifts when you charge in exchange for a utility payment; load management changes how hard you charge to protect your own panel. If the panel is the constraint, only one of those solves it.

4. ENERGY STAR, and the rebate it unlocks

Wallbox’s datasheet has a row that reads “ENERGY STAR certification: Yes”. Grizzl-E publishes no ENERGY STAR mark for the Ultimate 48A on either of its own pages for that unit.

That matters because ENERGY STAR is the most common eligibility filter in utility rebate programs, and a rebate is frequently worth more than the price gap between these two chargers. It is not a statement about efficiency in any sense a homeowner would notice — both units are near-identical pass-through devices. It is a certification that appears on a form.

One honest wrinkle in Grizzl-E’s favor: this is a model-by-model answer, not a brand-wide one. Grizzl-E doespublish a UL listing and ENERGY STAR for the unconnected Classic 40A, the cheapest unit in the table above. So if ENERGY STAR matters and you want a Grizzl-E, the dumb one qualifies and the 48-amp one does not — which is a strange place for a lineup to end up, and worth knowing before you file for a rebate. Our ENERGY STAR roundup lists everything in the registry that publishes the certification.

5. The app question, and a change we are flagging rather than hiding

Wallbox is straightforward. WiFi and Bluetooth, the Wallbox app and portal, permission management across user, admin and super-admin roles, over-the-air firmware with a published release-notes archive, and OCPP 1.6j. It is the more mature software of the two by some distance.

Grizzl-E is the complicated one, and the honest thing to do is show the working. Grizzl-E’s own Ultimate pages now describe a Wi-Fi, app-connected, OCPP charger— “a smart Wi-Fi-enabled Level 2 EVSE”, with a smart-function row reading “Wi-Fi (2.4 GHz); Mobile Application” and a protocol row reading “OCPP”. When we read the same spec page in September 2026 it published a DIP-switch selector and an LED and no connectivity at all.

We have not quietly rewritten the older record to match. The spec entry behind the Ultimate column in our table reflects the earlier reading, because the connectivity rows cannot be attributed with certainty to the specific J1772 SKU that entry describes — the SKU Grizzl-E’s page displays is the NACS one. A full re-spec of that unit is queued. In the meantime, the practical advice is simple: if the app is decisive for you, confirm the exact SKU with the seller before you buy, and treat Grizzl-E’s own page as the current word.

One more published oddity on the same page, recorded because it is the sort of thing that bites at install time: Grizzl-E’s headline for this unit is “48A 11.5 kW”, while its “Adjustable current” row reads “40A, 32A, 24A, 16A”. The 48 is not in its own adjustable list.

Which one to buy

Buy the Wallbox Pulsar Plus 48A if space is tight, if the panel needs load management, or if a utility rebate hinges on ENERGY STAR. It is the smallest and lightest 48-amp charger we track, the software is the better of the two, and it is the only one here that can throttle itself against the rest of the house. It is our pick for compact installs on the 48-amp roundup.

Buy the Grizzl-E Ultimate 48Aif the charger lives outdoors in real weather — particularly real heat. The 122F ceiling, the cast-aluminum enclosure and the 25-foot cold-flexible cable are what you are paying for, and they are the right things to pay for on a driveway or a detached garage. Accept the warranty ambiguity and the missing ENERGY STAR mark as the price.

Buy the Grizzl-E Classic Connect 40Aif a NEMA 14-50 outlet already exists. Same cast-aluminum body, same app, same 25-foot cable, on a plug you can take with you when you move — for six fewer miles of range per hour. The plug-in roundup is where it ranks.

Buy the Grizzl-E Classic 40A if you want nothing to log into. It is the cheapest unit here, it publishes both a UL listing and ENERGY STAR, and your car almost certainly schedules its own charging already. The case for it is made in full on the dumb-charger roundup.

If your car has a NACS port, both brands will sell you these units with a Tesla-style cable on the end — Grizzl-E across its whole connected lineup, Wallbox on the 40-amp plug-in and the 48-amp hardwired models. Our NACS roundup ranks that field.
