CyberPower P3WU Home Surge Protector with 4-Port USB Charging
Overview
The CyberPower P3WU is a compact wall-mount surge protector delivering 3 NEMA 5-15P AC outlets and four USB charging ports in a form factor small enough to disappear behind a desk or mount flush to a wall plate. At 49mm wide and 62mm tall, the P3WU fits into tight utility spaces — security desk corners, small server closets, or reception counters — without blocking adjacent outlets or requiring an extension cord just to reach the nearest socket. If you're deploying small surveillance workstations or access control readers alongside power-hungry tablets and phones, this is the kind of device that keeps the outlet count manageable without running additional power strips.
The P3WU ships in white and carries RoHS compliance, meaning it meets the EU restriction of hazardous substances standard — a baseline requirement for any deployment touching green-building specs or public-sector procurement checklists.
Key Features
- 3 NEMA 5-15P AC Outlets: Standard North American receptacles handle 125V devices directly — no adapters needed for typical surveillance peripherals like NVR power bricks, PoE injectors, or desktop monitors. Three outlets is a deliberate count: enough for the essentials, not so many that you're managing a tangle of cords from a single surge strip.
- 4 USB Charging Ports at 4.2A Total: Four lighted USB-A ports share a 4.2A pool. That's enough to simultaneously fast-charge two tablets and two phones without any port dropping to trickle speed — useful at a manned guard station or front-desk environment where staff cycle through multiple devices per shift. The lighted indicators tell you at a glance which ports are active.
- Wall-Mountable Design: The P3WU is rated for wall mounting, which matters in professional installs where floor clutter or dangling strips are a code or aesthetic issue. Wall-mounting also keeps the unit out of reach in child-safe or public-access environments — CyberPower explicitly rates this unit as safe for children, so it's appropriate in school lobbies, pediatric reception areas, or any space where ADA or childproofing standards apply.
- Cordless (Direct Plug-In) Form Factor: No power cord means no cable management headache and no strain on the wall outlet. The unit plugs directly into the receptacle, keeping the installation clean and reducing the chance of accidental disconnects in high-traffic areas.
- LED Indicators: Onboard LEDs provide at-a-glance status — no need to trace a cable to confirm the strip is live. In dim server rooms or under-desk installs, this matters more than it sounds.
- RoHS Compliance: Meets the EU Restriction of Hazardous Substances directive. Relevant if your deployment touches LEED-certified buildings, government facilities, or customers with environmental procurement policies requiring restricted-substance documentation.
- Compact Physical Footprint: At 49mm × 113mm × 62mm (W×D×H), the P3WU occupies minimal space. It won't block neighboring outlets on a standard duplex receptacle, and its depth of 113mm keeps it well clear of most electrical panel trim rings and recessed box covers.
Integration and Compatibility
The P3WU is designed around the NEMA 5-15P standard, which covers virtually all North American 15A wall receptacles. It draws from a standard 125V circuit — no dedicated circuit, no special wiring. For surge protectors and power accessories, this plug-and-play compatibility is the baseline expectation, and the P3WU meets it without caveats.
The four USB-A ports are compatible with any USB-A charging cable, covering the broad range of Android, iOS (via adapter), and proprietary device cables still in circulation across enterprise environments. If your deployment involves USB-C-only devices, plan for USB-C to USB-A adapters or a separate charging solution — the P3WU does not include USB-C ports based on available evidence.
For installations pairing this unit with small-footprint UPS and power protection systems, the P3WU handles the device-level outlet distribution while a UPS upstream handles battery backup — a common layered approach in access control and surveillance installs where uptime matters but full rack UPS capacity is overkill for a two- or three-device station.
Integrators sourcing from the broader CyberPower power protection line will find the P3WU fits naturally as the last-mile outlet solution in a layered power architecture.

Frequently Asked Questions
Q: How many devices can the P3WU charge via USB simultaneously?
A: The P3WU has four USB-A ports sharing a 4.2A total output. All four ports can charge simultaneously, though the available current per port depends on how many devices are connected and their individual draw. Two high-draw tablets plus two phones is a realistic simultaneous load.
Q: Can the P3WU be wall-mounted?
A: Yes. The P3WU is rated for wall mounting. It is also a direct plug-in (cordless) unit, meaning it plugs directly into a wall receptacle without a power cord.
Q: What is the input voltage for the P3WU?
A: The P3WU is rated for 125V nominal input, which is standard for North American residential and commercial electrical systems.
Q: Is the P3WU RoHS compliant?
A: Yes. The P3WU carries RoHS compliance certification, confirming it meets the EU Restriction of Hazardous Substances directive.
Q: Does the P3WU include USB-C ports?
A: Based on available product data, the P3WU includes four USB-A ports only. USB-C is not listed among the port types.
Q: Is the P3WU safe for use in public or child-accessible areas?
A: Yes. CyberPower rates the P3WU as safe for children, making it appropriate for deployment in school lobbies, pediatric offices, or other public-access environments.
The P3WU sits in a specific niche I see come up regularly: you need USB device charging and a couple of AC outlets at a manned station, but you don't want to run a full power strip and you definitely don't want a cord snaking across the floor. The direct plug-in, wall-mountable form factor at 49mm × 62mm face dimensions is genuinely practical here — it doesn't occlude the adjacent outlet on a standard duplex receptacle, which is the failure mode I see constantly with bulky direct-plug strips.
Technical Highlights:
- 4.2A USB Pool Across 4 Ports: At a typical security desk running two Android devices and two iOS devices simultaneously, 4.2A total is enough to maintain charge on all four without any port dropping to the 0.5A USB 2.0 floor. That's the spec that actually matters for shift-change scenarios.
- 125V / NEMA 5-15P: Dead-standard North American compatibility — no adapter, no rewire, no electrician call. Plugs into any 15A duplex receptacle. That's the right answer for rapid station deployment across multiple sites.
- RoHS Compliance: Not a buzzword here — if you're deploying into a LEED-certified building or a government facility with restricted-substance procurement requirements, RoHS documentation is a checkbox that has to be checked. The P3WU covers it.
Deployment Considerations:
- The cordless (direct plug-in) design means the unit's weight is entirely borne by the wall receptacle. In older commercial spaces where receptacles haven't been updated, verify the outlet box is securely fastened before wall-mounting — a loose box will cause the P3WU to sag over time.
- With only 3 AC outlets, plan your device count before committing. If a future station expansion adds a second monitor or a UPS bypass panel, you'll hit the outlet ceiling fast. For high-density outlet needs, pair upstream with a multi-outlet rack strip and use the P3WU strictly for USB charging consolidation.
The P3WU is the right call for a small-footprint guard station or reception counter where the priority is keeping USB devices charged and two or three AC peripherals powered, all without introducing floor-level cable clutter. Front-desk check-in environments in commercial buildings — where a tablet, a phone charger, and a receipt printer cover 90% of the outlet demand — are exactly where this unit earns its keep.
