Three-outlet wall tap with USB

The CyberPower CSP300WUR1 is a compact surge protector that plugs directly into a NEMA 5-15R receptacle. It provides three AC outlets and two USB charging ports rated at 2.1 amps. The unit is designed for indoor use at 125 volts and carries UL1363, UL1449 3rd Edition, cUL and RoHS certifications.

Replaces basic power strips without surge rating

This model upgrades an unprotected strip or a simple wall tap by adding 600 joules of surge suppression and EMI/RFI filtering from 150 kilohertz to 100 megahertz. The jump is worth it when you need to shield desktop peripherals, networking gear or charging devices from transient spikes on a 125-volt circuit.

Handles routine surges on a single circuit

The 600-joule rating and 30,000-amp maximum surge current protect connected equipment during common power events. Clamping voltage is 400 volts across line-neutral and line-ground modes with a response time under one nanosecond. Protection will exhaust after repeated large transients, so the unit is not suited for whole-room or high-value server deployments.

Questions about this item

Does the wall-tap plug need a grounded three-prong outlet to work?

Yes, the NEMA 5-15P input requires a grounded 125 V receptacle for the 600-joule MOV protection to function.

What is the most common mistake when plugging this unit in?

Inserting the wall tap into an ungrounded two-prong adapter defeats the L-N, L-G protection modes and voids the 400 V clamping spec.

How will I know when the 600-joule surge capacity is exhausted?

The protection indicator light will turn off, signalling the MOVs have absorbed their rated energy and the unit must be replaced.
