CyberPower 3-Outlet Wall Tap Surge Protector 900J

The CyberPower CSB300W is a compact 3-outlet wall-tap surge protector that delivers 900 joules of transient suppression and clean power filtering for home or small office electronics.

Compact and purpose-built, the CSB300W fits directly into a wall socket to protect routers, modems, laptops, chargers, and other personal devices where space is limited. It combines surge dissipation with EMI/RFI line filtering and visual grounding/protection indicators, giving a simple, low-profile way to reduce the risk from voltage spikes and line noise without a long power cord or bulky strip.

How does the CSB300W protect my devices from spikes and surges?

This unit uses a metal-oxide varistor (MOV) to redirect excess voltage away from connected equipment, dissipating transient energy into the ground path. It’s rated at 900 joules, which helps absorb many common surges, and the UL listing confirms it meets safety standards for surge suppressors.

• 900-joule surge absorption capacity for transient events
• MOV technology diverts dangerous voltage spikes to ground
• UL listing ensures independently tested safety compliance

Will it reduce interference and improve signal quality?

Yes — the CSB300W includes EMI/RFI filtering to block electromagnetic and radio-frequency interference that can introduce noise into audio, video, and network equipment. While it won’t increase bandwidth, it helps maintain cleaner power and clearer signals for connected devices.

• EMI/RFI filters reduce line noise for audio, video, and networking gear
• Cleaner power can lead to fewer data errors and improved device stability
• Especially useful near routers, modems, and home entertainment setups

What practical features make it easy to use in a home or office?

The CSB300W is a wall-tap design that plugs directly into an outlet, saving floor and desk space compared with a corded power strip. Three widely spaced outlets accept multiple plugs and adapters, and two LED indicators show whether the unit is grounded and actively protecting your devices.

• Wall-tap form factor for a low-profile, space-saving installation
• Three outlets accommodate several plugs or charger bricks
• Two LED lights provide quick status for grounding and surge protection

What warranty and protection guarantees come with this product?

CyberPower backs the CSB300W with a limited lifetime warranty and a connected equipment guarantee. The included financial coverage helps provide additional peace of mind should a properly connected device be damaged by a covered surge.

• Limited lifetime warranty from CyberPower
• $50,000 connected equipment guarantee for qualifying claims
• Instructions and labeling to help maintain warranty eligibility

Who is this for? The CyberPower CSB300W is designed for anyone needing discreet surge protection without the bulk of a corded strip — ideal for apartment dwellers, small offices, home networking closets, or bedside setups. It’s a practical choice when you want straightforward protection for routers, modems, chargers, small desktop electronics, and entertainment devices in locations where space and outlet access are limited.
