Charging speed: identical, and worth saying plainly
Both are 48-amp chargers. Forty-eight amps at 240 volts is about 11.5 kW, and at our standard reference of roughly 3.5 miles of range per kWh that is about 40 miles of range per hour for both — roughly 400 miles across a ten-hour overnight window.
There is no speed difference here at all, and there is no version of this comparison where paying more gets the car charged faster. Anyone suggesting otherwise is describing something that does not exist: amperage times voltage is the entire calculation, and both units also need the same 60-amp circuit under the National Electrical Code’s 125% continuous-load rule to reach it.
The one asterisk favors Emporia. On a NEMA 14-50 plug it runs at 40 amps rather than 48, because the receptacle is a 50-amp device — but the Wallbox cannot be plugged in at all, so that is an option Emporia has and Wallbox does not, rather than a limitation.
Size: the Wallbox’s actual differentiator
The Pulsar Plus is among the most compact 48-amp chargers you can buy, and that is not a cosmetic point. It matters in three specific situations.
A narrow garage. A charger on the wall of a single-car garage is something you walk past, squeeze around, and occasionally reverse toward. A smaller box is a genuinely better daily experience there.
Two chargers on one wall. If you are planning for two EVs, fitting two units side by side is much easier with a compact body. Our two-EV roundup covers the wider problem.
Awkward mounting.Between a window and a door, above a workbench, beside a panel — the places a charger actually has to go are often constrained, and a smaller unit gives the electrician more options about where the circuit lands.
If none of those describes your wall, size is a feature you are paying for and will not notice.
Load balancing versus energy monitoring
Both chargers have a signature software feature and they point in different directions.
Wallbox Power Boostis load balancing: the charger reduces its own draw so total household demand stays inside what the service can carry. That can be the difference between fitting a 48-amp charger onto an already-busy panel and being told you need a service upgrade — which is typically the largest single line on an EV charging quote. If your electrician has raised capacity concerns, this is the feature to price against the upgrade.
Emporia’s appis built around energy tracking and integrates with Emporia’s wider home energy monitoring platform. It tells you what charging is actually adding to your electricity bill rather than just when it happened. That is genuinely useful, and it is a different kind of useful: it informs you rather than solving an electrical constraint.
Note that Emporia also sells load management under the name PowerSmart, standard on the Emporia Proand available as an add-on, and that Emporia publishes it as requiring their Vue energy monitor — a second device. So if load management is the reason you are here, the honest comparison is Wallbox against the Emporia Pro, not against the standard Emporia on this page.
Hardwired only versus both
This is the difference most likely to decide the purchase, and it gets less attention than it deserves.
The Wallbox Pulsar Plus is hardwired only. There is no plug-in version. That means an electrician terminates it permanently, it stays with the house when you move, and replacing it outside warranty is a service call rather than a swap.
The Emporia is sold hardwired or with a NEMA 14-50 plug. That flexibility is worth real money to a renter, to anyone likely to move within a few years, and to anyone who would rather be able to replace the unit themselves. The cost is the capped 40 amps on the plug-in configuration.
Our hardwired vs plug-in comparison covers the trade in full. The short version: if you rent, this section ends the comparison in Emporia’s favor regardless of anything else on this page.
Certification, enclosure and the small print
Enclosure.Both publish NEMA 4 — sealed against windblown dust and hose-directed water, suitable for an outdoor wall. Neither is NEMA 4X; if you are near salt air, the Autel MaxiCharger is the unit that publishes corrosion resistance.
Certification. Emporia is UL listed against the ANSI/UL 2594 EV supply equipment standard and ENERGY STAR certified. Wallbox publishes ENERGY STAR certification. Both are legitimate, independently listed products; our guide to reading certifications explains what these marks do and do not tell you.
Cable and warranty.Both 25 feet, both three years. A wash on both counts — and 25 feet is at the top of the class, as our reach roundup covers.
The verdict, by buyer
Buy the Emporia Level 2 in most cases. It is the same charging speed, the same cable, the same enclosure rating and the same warranty for less money, plus the option to plug it in rather than wire it in. That last point alone makes it the right answer for renters and for anyone who expects to move. It is our value pick across the site for these reasons.
Buy the Wallbox Pulsar Plusif your wall is genuinely tight, if you are fitting two chargers side by side, or if Power Boost load balancing is what lets a 48-amp charger fit onto your panel at all. In that last case it is not a premium purchase — it is the cheaper alternative to a service upgrade, and it is the reason it leads our hardwired roundup.
Buy neither if your panel simply cannot take 48 amps with any amount of management: step down to a 40-amp charger on a 50-amp circuit and accept about six fewer miles of range per hour, as our 40A vs 48A comparison explains. And if you want adjustable amperage so the charger can follow whatever circuit you end up with, the ChargePoint Home Flex is the unit that does that.
