What is a Power Strip?
A power strip is an electrical device that splits a single wall outlet into multiple sockets, allowing you to connect several appliances and gadgets simultaneously. Most power strips include an extension cord, making it easy to bring power to locations farther from the wall. Modern power strips have evolved well beyond simple “extension cords with extra plugs.” Many now integrate USB ports for direct device charging, surge protection circuits to safeguard expensive electronics, individual outlet switches for energy management, and even USB PD ports that can fast-charge laptops and tablets. Whether you are setting up a home office desk, an entertainment center, or a workshop, the right power strip keeps your devices powered safely and your cables organized.
In-Depth
Basic Construction
A power strip consists of a plug (which connects to the wall outlet), a power cable, and a housing with multiple outlet sockets. Internally, copper conductors distribute the electricity from the wall to each socket. In most countries, the maximum rated load is around 1,500 watts (15 amps at 120 volts in North America, or about 3,000 watts at 240 volts in regions with higher mains voltage). It is critical that the combined power draw of all connected devices does not exceed this rating, as overloading can cause overheating and fire hazards.
Types of Power Strips
| Type | Features | Best For |
|---|---|---|
| Basic extension | Simple cord with extra outlets | Adding more sockets in any room |
| Tower / vertical | Upright design, saves desk space | Desk setups with many devices |
| USB-equipped | Built-in USB-A and USB-C ports | Charging phones and tablets without adapters |
| Surge-protected | Internal MOV or similar surge suppression | Protecting computers and AV equipment |
| Magnetic-mount | Magnets on the back for metal surfaces | Attaching to steel desks or workshop benches |
For desk setups, a power strip with USB-C ports supporting PD charging is especially convenient. It eliminates the need for separate chargers and keeps the desk tidy.
Safety Considerations
Safe usage of power strips is essential. Daisy-chaining (plugging one power strip into another) is strongly discouraged because the combined load can easily exceed the rated capacity, creating a serious fire risk. Power strips also have a finite lifespan, typically three to five years, after which internal components can degrade. Signs that it is time to replace your power strip include frayed or discolored cords, loose-fitting plugs, visible scorch marks, or a warm-to-the-touch housing during use.
How to Choose
1. Count the Outlets and Check Spacing
Large AC adapters, often called “wall warts,” can block adjacent sockets. Look for power strips with widely spaced outlets or alternating orientations that accommodate bulky plugs. As a rule of thumb, choose a strip with one or two more outlets than you currently need to allow for future expansion.
2. Prioritize Safety Features
Individual outlet switches let you turn off unused sockets to save energy and reduce standby power draw. Surge protection shields sensitive electronics from voltage spikes caused by lightning or power grid fluctuations. Dust-prevention shutters and fire-resistant housing materials add further layers of safety. For any setup involving computers or AV equipment, surge protection is essentially non-negotiable.
3. Evaluate Cord Length and Gauge
Choose a cord length that suits your room layout, but also pay attention to the wire gauge (cross-sectional area). Thicker conductors handle higher loads more safely. If you plan to run power-hungry appliances such as space heaters or high-wattage monitors, select a power strip with a heavier-gauge cord.

Power strips range from basic surge-protected outlet extenders to smart Wi-Fi strips with individual outlet control, USB charging ports, and energy monitoring. The picks below cover the best overall surge-protecting power strip for desks, the top smart power strip for home automation users, and the best flat-plug travel-safe model for furniture placement.
| Product | Highlights | Price Tier |
|---|---|---|
| APC PE6 SurgeArrest | 6 outlets, 1080 J surge, right-angle plug, coax/phone protection | Budget |
| Kasa Smart Power Strip EP40M | 4 outlets + 4 USB, Wi-Fi, Alexa/Google, energy monitoring | Mid-range |

APC SurgeArrest PE6 — Best Value Surge-Protected Power Strip
The APC SurgeArrest PE6 is one of the most consistently recommended power strips across tech forums and consumer review sites because it combines a 1080-joule surge protection rating, coaxial and telephone line protection, and APC’s equipment protection policy — which covers connected devices against surge damage up to $75,000 — in a compact six-outlet strip at a budget price. The 90-degree right-angle plug fits neatly behind furniture without the flat plug protruding awkwardly. The six outlets are spaced generously enough to accommodate most wall adapters side-by-side without blocking neighboring outlets. A status light confirms active surge protection, alerting you if the suppression components have been sacrificed in a previous event and need replacement. For the average home user who needs a surge-protected strip for a TV entertainment center, home office desk, or gaming setup without the complexity of smart controls, the APC PE6 provides reliable protection at the lowest cost of any reputable brand.
Kasa Smart Power Strip EP40M — Best Smart Power Strip for Home Automation
The Kasa EP40M combines four individually switchable smart AC outlets with four USB-A charging ports in a single strip, all controllable via the Kasa app, Amazon Alexa, and Google Home. Individual outlet control means you can schedule your coffee maker, turn off the TV from across the room, or cut power to a gaming PC in a child’s room via a smartphone. Energy monitoring tracks per-outlet power consumption in real time, revealing standby power drains from appliances you did not know were drawing current. The 2500 J surge protection rating is among the highest in the smart strip category. Setup requires only a 2.4 GHz Wi-Fi network and the Kasa app; no hub is needed. Four USB-A ports (combined 24 W) charge phones and tablets directly without occupying AC outlets. The EP40M does not include USB-C PD ports, which is a gap for users with modern phones requiring fast USB-C charging. For Amazon Echo or Google Home users who want to bring their desk or entertainment center into a smart home ecosystem, the Kasa EP40M is the most feature-complete smart power strip at a competitive price.
Tripp Lite TLP725 — Best Heavy-Duty Surge-Protected Power Strip
The Tripp Lite TLP725 is designed for users who need maximum surge protection capacity: a 2880-joule rating (nearly triple the APC PE6) and a right-angle flat plug on a 7-foot power cord. Seven outlets accommodate a full workstation — desktop, dual monitors, speakers, USB hub, desk lamp, and a backup drive — without a second strip. Tel/DSL and coaxial connections are protected alongside AC. Tripp Lite backs connected equipment with a $75,000 ultimate lifetime insurance policy, and a strip indicator light confirms that protection is still active. The 7-foot cord provides flexibility for routing power across a desk or behind furniture without an extension cord. A keyhole slot on the back allows wall-mounting behind an entertainment center. For home offices, server closets, or A/V racks where multiple devices need surge protection and outlet count is a priority, the TLP725 offers the highest joule rating in a non-UPS strip format.
The Bottom Line
A power strip is one of the most ubiquitous yet underappreciated accessories in any home or office. The right model provides not just extra outlets but also USB charging, surge protection, and smart energy management features. Focus on outlet count and spacing, safety certifications, and cord specifications to find a strip that matches your environment. Replacing aging power strips on schedule is a small investment that goes a long way toward preventing electrical hazards.
