CyberPower P2WU Wall-Tap Surge Protector with USB Charging
Overview
The CyberPower P2WU is a compact, cordless wall-tap surge protector that plugs directly into a standard NEMA 5-15P outlet and delivers 2 protected AC receptacles plus 3 USB charging ports — all without consuming floor space or adding cable clutter. With a 500-joule surge energy rating and a $50,000 Connected Equipment Guarantee, the P2WU is built for environments where you need reliable transient protection at the point of use: IP camera power injectors, desk VoIP phones, small network appliances, or workstation peripherals where a full power strip is overkill and a bare outlet offers zero protection.
Key Features
- 500-Joule Surge Energy Rating: 500 joules absorbs meaningful transient events — line-voltage spikes from HVAC switching, nearby lightning strikes on shared branch circuits, or grid noise from industrial equipment. That headroom matters in commercial installations where utility power quality is inconsistent.
- 800V Clamping Voltage: When a surge hits, the P2WU clamps at 800V — the threshold at which energy is diverted rather than passed through to your equipment. Lower clamping voltage means better protection; 800V is the UL 1449 standard threshold for let-through voltage, keeping sensitive electronics within safe operating margins.
- 0.001ms Response Time: At one nanosecond effective response, the MOV protection circuit reacts faster than virtually any connected device's internal protection can respond. By the time a transient is measurable at the load, the P2WU has already begun clamping.
- 2 NEMA 5-15R AC Outlets: Both receptacles accept standard 3-prong plugs — wall warts, brick-style power supplies, or direct-plug devices. The cordless wall-tap form factor means both outlets are surge-protected with no additional wiring run.
- 3 USB Ports, 4.2A Combined Output: Three USB-A charging ports share a 4.2A pool — enough to simultaneously charge a tablet and two smartphones, or to keep a PoE injector's management console, a wireless keyboard dongle receiver hub, and a barcode scanner dock powered without pulling an additional outlet.
- EMI/RFI Noise Filtering: Electromagnetic and radio-frequency interference from motors, ballasts, and switching power supplies on the same circuit can corrupt serial data, cause false triggers on analog inputs, and degrade audio. The built-in EMI/RFI filter attenuates that noise before it reaches connected equipment — useful wherever sensitive electronics share a circuit with HVAC or lighting loads.
- Cordless Wall-Tap Design: No power cord means no cable management overhead. The P2WU installs directly at the outlet — ideal for camera installation kits, access control panel power feeds, or any mounting location where a cord would violate raceway or aesthetic requirements.
- $50,000 Connected Equipment Guarantee (CEG): CyberPower backs connected equipment up to $50,000 if a surge passes through the P2WU and damages attached devices while the unit is operating within spec. This provides a concrete financial backstop for IT and security hardware at the protected outlet.
- RoHS Compliant: The P2WU meets Restriction of Hazardous Substances directive requirements — relevant for deployments in regulated environments (healthcare, education, government) where material compliance documentation is part of procurement.
- Compact Form Factor — 75mm × 82mm Footprint: At 75mm wide by 82mm deep, the P2WU adds minimal protrusion from the wall plate. It fits in standard electrical boxes without blocking adjacent outlets on a duplex receptacle in most configurations.
Integration & Compatibility
The P2WU accepts a standard NEMA 5-15P plug connection and fits any 120V/125V AC outlet on a standard North American branch circuit. The two NEMA 5-15R outlets accommodate the majority of commercial security and networking hardware power supplies. The 3 USB ports charge any device following standard USB-A charging protocols — no proprietary charging technology is required from the connected device side.
For deployments pairing the P2WU with CyberPower UPS systems or inline power conditioning, note that the P2WU is a surge-only device — it provides no battery backup, no voltage regulation, and no AVR. For sustained power protection during outages, pair it with a UPS on the upstream circuit. The power protection category includes compatible CyberPower UPS units sized for security and networking loads.
The wall-tap form factor installs without tools in any standard duplex outlet. The white finish matches standard residential and commercial electrical hardware. No driver or software configuration is required — protection is passive and always-on once plugged in.
Frequently Asked Questions
Q: Does the P2WU provide battery backup or voltage regulation?
A: No. The P2WU is a surge-only device — it absorbs and clamps transient voltage spikes but does not supply battery power during outages and does not regulate sustained over- or under-voltage conditions. For those functions, pair it with a UPS on the upstream circuit.
Q: What does the $50,000 Connected Equipment Guarantee cover?
A: CyberPower's $50,000 CEG covers repair or replacement of connected equipment damaged by a surge that passes through the P2WU while it is operating correctly and within its rated specifications. Claims are subject to CyberPower's warranty terms and conditions.
Q: How many devices can I charge simultaneously from the USB ports?
A: The three USB-A ports share a combined 4.2A output. You can charge up to three devices simultaneously; total draw across all three ports cannot exceed 4.2A. Charging speed per device will vary depending on how many ports are in use at once.
Q: Will the P2WU block the adjacent outlet on a standard duplex receptacle?
A: At 75mm wide by 82mm deep, the P2WU has a compact footprint that fits most standard wall plates without blocking the second outlet, though this depends on the specific outlet plate and wall box configuration. Verify clearance in tight or non-standard enclosures before installation.
Q: Is the P2WU rated for outdoor use?
A: No IP environmental rating is specified for the P2WU. It is intended for indoor use at standard 120V/125V AC outlets. Do not install in wet, damp, or outdoor locations.
Q: Is the P2WU RoHS compliant?
A: Yes. The P2WU carries RoHS compliance certification, making it suitable for regulated procurement environments that require hazardous substances documentation.
I spec the P2WU into point-of-use protection roles where a full power strip would be over-engineered and an unprotected outlet is genuinely risky. The 800V clamping voltage combined with the 0.001ms response time means transients on a shared commercial branch circuit — HVAC switching, fluorescent ballast noise, inductive load kickback — get absorbed before they reach the connected device's internal power supply. For a PoE injector feeding a dome camera or a VoIP phone at a reception desk, that protection is real and the cordless form factor makes installation clean.
Technical Highlights:
- 500J Surge Rating: Provides meaningful transient absorption capacity for commercial-grade branch circuits — not a paper spec. 500 joules handles repetitive low-level surges over time without immediate MOV degradation.
- 3 USB Ports @ 4.2A Combined: More useful than it sounds at a security installation — charges a tablet used for VMS mobile review, a handheld scanner, and a radio simultaneously without pulling a second outlet.
- $50,000 CEG: A concrete backstop for the IT hardware at the outlet — not just a marketing claim, but a documented CyberPower liability commitment tied to correct product operation.
Deployment Considerations:
- The P2WU is surge-only — no AVR, no battery. If the upstream circuit experiences sustained sags or brownouts (common in older commercial buildings), the connected equipment is unprotected against those conditions. Put a UPS upstream if voltage regulation matters.
- The 75mm × 82mm body fits most standard outlet plates, but verify clearance before specifying in shallow-box or industrial enclosure installations where the adjacent outlet must remain accessible.
The P2WU is the right call for light-duty security hardware installs — a camera power injector, a door controller's auxiliary power feed, or a desk IP phone — where you want documented surge protection and USB charging at the outlet without running a power strip or additional conduit.
