The short answer
The Wallbox Pulsar Plus delivers 48 A / 11.5 kW from a body measuring 7.8 in W x 3.9 in D x 7.9 in H — genuinely the smallest 48 A charger available, and a deciding factor when the only spot left is a narrow strip of wall. It is NEMA Type 4 per UL 50E with a 25 ft cable, a three-year limited warranty, and Bluetooth control that works without an internet connection. Its weakness is the operating range: -22 degF to 104 degF, the narrowest cold rating of the units we recommend.
Footprint is an under-discussed spec. In a garage with two cars, shelving, a freezer and a panel, “where does the box actually go” is a real constraint, and most 48 A chargers are considerably larger than this one.
Who this is for
- A crowded garage. If the available wall is narrow, between the panel and a doorway, or above a workbench, the size difference is the purchase.
- Anyone who wants 48 A with offline control. Bluetooth scheduling works without internet, which means a Wi-Fi outage or a cloud problem does not change your charging.
- A moderate climate. The -22 degF lower limit is fine in most of the US and marginal in the upper Midwest and northern New England.
- Anyone cross-shopping NACS and J1772, since Wallbox sells both and a 40 A NACS version as well.
Who should buy something else instead
- An unheated garage where it gets properly cold. -22 degF is the narrowest rating here. The Autel MaxiCharger is rated to -40 degF, and the Grizzl-E Classic's cast-aluminum body is the more robust outdoor package.
- Your panel is tight. No whole-home load management. The Emporia Pro measures and throttles, and costs less.
- You want the same charge rate for less. The EVIQO 48 A delivers an identical 11.5 kW with a 25 ft cable for meaningfully less money.
- You need a plug-in unit. The 48 A Pulsar Plus is hardwired. A renter should look at portable chargers.
The size comparison
Where manufacturers publish dimensions, the Pulsar Plus is consistently the smallest 48 A unit. The practical consequence is that it fits places other chargers do not: beside a panel without encroaching on the working space NEC 110.26 requires, above a bench, or in the narrow run between a garage door track and a corner.
Bluetooth without internet is the under-rated feature
Most smart chargers route control through a cloud service. That works until it does not: a Wi-Fi outage, an account problem, a company's server migration, or a service being retired years after you bought the hardware.
The Pulsar Plus can be managed over Bluetooth directly, which means scheduling and amperage changes do not depend on anything outside your garage. On a device you are keeping for a decade, that is a genuine resilience feature rather than a convenience one — and it is the question we think people should ask about any smart charger. More on that.
What this charger needs from your electrical system
| Item | Requirement | Code basis |
|---|---|---|
| Charger output | 48 A / 11.5 kW | Manufacturer published |
| Breaker | 60 A, two-pole | NEC 625.41 — 125% of a continuous load; NEC 625.42 makes EV charging continuous |
| Copper conductor (conduit, 75 degC) | 6 AWG | NEC Table 310.16 |
| GFCI breaker | Not required — NEC 625.54 covers receptacles | NEC 625.54 |
| Install type | hardwired | Manufacturer published |
Known issues, from owner reports
- The -22 degF lower limit is the clearest limitation. In a cold climate it is the reason to choose something else.
- Hardwired only at 48 A, so it does not move with you.
- No whole-home load management, which on a marginal panel is the feature you want.
- Owners report occasional app and firmware friction, as with most connected chargers. The Bluetooth fallback mitigates it.
- Priced above units delivering the same charge rate. You are paying for the footprint and the build, which is a legitimate trade if the footprint is your constraint.
What the install needs
A 60 A two-pole breaker and 6 AWG copper for 48 A, per NEC 625.41 and Table 310.16. Hardwired, so no GFCI breaker is required under NEC 625.54 — which removes a part cost and the most common nuisance-tripping cause.
Rated NEMA Type 4 per UL 50E for indoor or outdoor installation. If it is going outside in a cold region, weigh the -22 degF figure against the Autel or the Grizzl-E before committing.
