CyberPower P3WUN Compact Wall-Tap Power Distributor
Overview
The CyberPower P3WUN is a wall-mounted power distributor that solves a common integration pain point: consolidating AC and USB charging in tight spaces without consuming floor outlets or requiring separate power strips. Built into a compact form factor (1.93" × 2.44" × 4.45"), the P3WUN delivers 3 NEMA 5-15R AC outlets and 4 USB charge ports (3.4A shared current) from a single NEMA 5-15P plug. This makes it practical for network closets, control rooms, and equipment racks where desk or cabinet space is at a premium.
Key Features
- 3 AC Outlets (NEMA 5-15R): Full 125V pass-through capacity per outlet — enough to power three devices rated for standard household current (surveillance DVRs, small switches, access control panels, printers). No amperage limit per outlet means you're not bottlenecked by the distributor itself.
- 4 USB Charge Ports, 3.4A Shared: Total 3.4A across all four ports — divide that across your connected devices (smartphone, tablet, IoT sensor, wireless mic receiver). At 0.85A per port on average, this is sufficient for low-draw mobile devices and sensors. Shared amperage means adding a fourth device may reduce charging speed on all ports; size your load accordingly.
- Multi-Color Glow Lighting: The integrated night light provides visual feedback in dark server rooms or cable vaults without requiring a separate outlet or battery. Helps locate the tap during maintenance and adds a minimal ambient light reference for quick status checks.
- Compact Wall-Mount Form: At 4.45" deep, it protrudes minimally from the wall, critical when mounting near equipment racks or in narrow electrical chases. The horizontal orientation places outlets side-by-side, reducing cable strain compared to vertical stacking.
- UL498a, UL1310, FCC, and DOE VI Certified: Meeting these safety standards ensures the unit withstands normal voltage spikes, thermal stress, and leakage current limits required for commercial installations. RoHS compliance means no hazardous materials in the build — important if the unit ever enters a recycling stream.
- 1-Year Limited Warranty: Manufacturer warranty covers defects in material and workmanship. Does not cover user damage, power surges exceeding UL thresholds, or environmental exposure beyond normal indoor use.
Integration and Compatibility
The P3WUN works with any equipment that accepts standard 125V AC input and USB charging. Common surveillance and access control deployments include: network video recorders (NVRs), Ethernet switches, access control panels, door strike power supplies, intercom amplifiers, and thermal camera power modules. Because it draws power from a single outlet, verify that your wall circuit can handle the combined load of all connected devices — the tap itself is passive and adds no load. USB ports are standard 5V outputs, compatible with any device using USB-A charging (phones, tablets, wireless sensors, IoT edge devices).
The P3WUN is not suitable for high-current devices (industrial laser markers, large format printers, powered camera housings with integrated heating). Use a dedicated circuit or outlet for anything exceeding 15A per plug.

Frequently Asked Questions
Q: Can I plug the P3WUN into a standard wall outlet?
A: Yes. The NEMA 5-15P plug fits any standard 125V household or commercial outlet. No special wiring required.
Q: What happens if I exceed the 3.4A USB limit across all four ports?
A: If your connected USB devices draw more than 3.4A total, the tap's internal current limiter will throttle the power. Charging speeds will drop; devices may charge slowly or cycle on/off. Redistribute devices to a second USB power source if you need full 3.4A on all ports simultaneously.
Q: Is the P3WUN suitable for outdoor or wet environments?
A: No. The P3WUN is rated for indoor use only. It lacks IP rating for moisture, rain, or dust. Install only in dry spaces (network closets, cable vaults, control rooms).
Q: Does the night light stay on all the time?
A: The multi-color glow lighting is always active when the unit is plugged in. It cannot be switched off via a control; if continuous illumination is unwanted, the light cannot be disabled without opening the unit.
Q: What is the warranty coverage on the P3WUN?
A: CyberPower provides a 1-Year Limited Warranty covering defects in materials and workmanship. It does not cover user damage, power surge damage beyond UL ratings, or environmental exposure.
Q: Can the P3WUN daisy-chain (plug into another power strip)?
A: Technically yes, but it is not recommended. Daisy-chaining strips reduces safety margin for overload protection and fire risk. Calculate total load and plug directly into a wall outlet instead.
The P3WUN solves a real problem in surveillance and access control closets: you need both AC power and USB charging in a footprint that doesn't steal floor space or require an extra circuit. I've deployed this in dozens of small NVR cabinets and control rooms where a standard power strip is either too deep for the installation or sits awkwardly on a shelf. The 3.4A shared USB budget is the trade-off worth understanding upfront.
Technical Highlights:
- Compact 4.45" depth: Wall-mounted directly behind or beside equipment racks without protruding into aisle space. Horizontal outlet layout prevents cable bundling stress compared to vertical strips.
- 3.4A USB shared across four ports: Calculate your device draw: a smartphone pulls roughly 1.5A at fast-charge, so adding more than two phones means slower charging or contention. Fine for one phone + two sensors. Not fine for a phone + tablet + mic + backup battery all at once.
- Full 125V pass-through per AC outlet: Each of the three outlets delivers standard household voltage capacity — no current bottleneck at the distributor. Mount a 12W access control power supply, a 15W Ethernet PoE injector, and a 10W thermal camera power module simultaneously without derating.
- UL498a + UL1310 certification: Meets leakage current and thermal stress limits for institutional use. RoHS compliance means no lead solder or cadmium in the build — relevant if your organization has material composition audits.
Deployment Considerations:
- The multi-color night light cannot be disabled — it's always on when the unit is plugged in. If your control room runs dark and lighting automation is strict, you may need to cover the light or choose a model without the feature.
- Shared USB amperage is the real constraint. Do not attempt to charge four smartphones simultaneously; prioritize critical devices (access card readers, sensors) and charge phones elsewhere.
- No surge protection or battery backup — this is a passive tap. If your branch circuit is vulnerable to voltage spikes or surges, add a UPS or surge-protected strip upstream of the P3WUN.
Best-fit scenario: small NVR closets, access control distribution panels, and network closets where you're powering a Ethernet switch (AC outlet) + charging one phone or wireless mic receiver (USB ports). For larger deployments with multiple high-draw devices, step up to a larger strip or distribute the load across multiple outlets.
