What makes it stand out
The Pulsar Plus wins two arguments at once. First, footprint: at 7.8 × 7.9 × 3.9 inches and 4.4 pounds without the cable it’s among the smallest 48-amp chargers on the market, a compact square you can tuck beside a door or into a narrow garage bay where a bigger unit wouldn’t fit. Second, brains: it carries both WiFi and Bluetooth, an ENERGY STAR listing, UL 2594 and UL 2231 certification, OCPP 1.6j, a 25-foot cable and a NEMA Type 4 enclosure rated per UL 50E for indoor and outdoor installation, wrapped in an app that Wallbox has spent years refining. Add a 3-year warranty and you have a charger that feels premium in the hand and in software — which is the point, because it is priced as a premium product.
One environmental spec is worth flagging because it is tighter than the competition’s. Wallbox publishes an operating range of -22°F to 104°F. The cold end is normal; the hot end is not — ChargePoint publishes 122°F and Autel 131°F. For a shaded garage wall that is a non-issue. For a west-facing exterior wall in Phoenix it is worth a thought, and outdoor chargers covers the units built for it.
The lineup, as Wallbox sells it today
This is the section we got wrong at launch, so it gets its own table. Wallbox’s current North America datasheet lists two electrical models, each available with either a J1772 or a factory NACS connector:
| Model | Power | Connection type | Circuit |
|---|
| 48 A | 11.5 kW | Hardwired | 60 A |
| 40 A | 9.6 kW | NEMA 14-50 plug or hardwired | 50 A |
So the honest statement is not “hardwired only” but “hardwired only at 48 amps”. If you rent, or want a charger that comes off the wall when you move, the 40-amp Pulsar Plus on a NEMA 14-50 is a real option — you trade about 6 miles of range an hour for it, which for most drivers is invisible overnight. Either model can also be dialed down: Wallbox lists a hardware current selector from 16 amps and software control from 6 amps up to the rated current. Our review card above, and the specs on this site generally, describe the 48-amp unit.
Dynamic load management: sharing a circuit instead of upgrading the panel
Adding a 48-amp charger normally means a dedicated 60-amp circuit, and if your panel is already close to full that can force an expensive service upgrade. Wallbox’s answer — marketed as Power Boost when we first wrote this, now published as Static Load Management and Dynamic Load Management — is to let the charger watch your home’s total draw and dial its own output up or down in real time so the combined load never exceeds what your service can handle. When the dryer and oven are running, the charger eases off; when the house is quiet overnight, it pulls full power.
Two practical notes before you count on it. Wallbox footnotes both load management and its solar-charging feature with “may require power meter accessory” — that meter is a separate purchase, listed at $299 on Wallbox’s own US store on the day we checked, so budget for it rather than assuming it’s in the box. And solar charging, per Wallbox, is not compatible with multiple-charger installations or with OCPP. For homes where a panel upgrade would cost more than the charger, the capability still pays for itself easily — but work out whether you need it first with our panel capacity guide, and compare it against the standalone devices in load management.
Charging speed, worked out
The arithmetic is the same as any 48-amp charger. At 48 amps and 240 volts the Pulsar Plus delivers 11.5 kW (48 × 240 = 11,520 watts). Using our standard reference of about 3.5 miles of range per kWh, that’s roughly 40 miles of range per hour — a large battery refills in a night with room to spare, and the 30–60 miles most people drive daily is a one-to-two-hour top-up. The 40-amp model works out at 9.6 kW and about 34 miles an hour. The wrinkle unique to this charger is that load management can deliberately hold the output below the rated current to protect a shared circuit, so on a load-balanced install your steady rate depends on what else in the house is drawing power at the time. As always, your real number tracks your car’s efficiency, which is why we state the 3.5 mi/kWh assumption.
The app, the firmware and OCPP
Wallbox’s app handles the things a smart charger should: play, pause, lock, scheduling and session data, over WiFi or Bluetooth — and the Bluetooth link is a genuine advantage in a detached garage where WiFi doesn’t reach, because you keep local control when the network doesn’t.
Firmware arrives over the air, and Wallbox publishes a release-notes archive rather than leaving you guessing. As of this refresh the current North America build listed for the Pulsar Plus NA (hardware PUP1) is software 6.8.14, released 18 February 2026; the newer PUP2 hardware, sold as Pulsar Plus e, is on 6.11.26, released 22 April 2026. Check which revision you have in the app before matching a version to it — the two lines do not share a version sequence, which is a genuinely confusing bit of Wallbox housekeeping.
The OCPP 1.6j support is the sleeper feature. It means the charger is not permanently married to Wallbox’s cloud: if your utility runs a managed-charging program on a third-party platform, or you simply want to move off a vendor app in five years, the protocol is there. Very few home chargers at any price offer it.
The install
Because EV charging is a continuous load, the circuit is sized to 125% of the current — the NEC “80% rule” — so the full 48 amps needs a 60-amp circuit and a licensed electrician, and the 40-amp model needs a 50-amp one. If your panel can’t spare that, load management may let you share an existing circuit instead of upgrading; if you’d rather keep the option to plug in and move the charger, take the 40-amp version and see our hardwired vs plug-in comparison. What the electrical work itself costs is itemized in our install cost breakdown, and because this is a hardwired job in most cases, the labor line matters more than usual — installation cost by state shows what it should run where you live.
Who should buy it — and who should skip it
Buy it if you have a tight space, a nearly full panel, or both: the compact body fits where others won’t, and dynamic load management can let you add a fast charger without the cost and disruption of a service upgrade. The NACS option and OCPP support both age well. If you want a polished premium smart charger and the hardwired install is fine by you, it earns its price.
Skip it if you’re price-driven. The Emporia Level 2 gives you the same 48 amps and a real energy-tracking app for a good deal less, with the same hardwired-or-plug-in choice. If you want adjustable amperage across a wider range, over-the-air firmware and the most mature app in a larger body, the ChargePoint Home Flex is the other premium pick — and Wallbox vs ChargePoint is the page that decides between them. The Pulsar Plus is the answer to a specific problem — small space or a tight panel — not the cheapest way to charge.
