Power Strips, Outlet Bars & Surge Protectors
Power strips and mains distribution blocks let you plug several devices into a single wall outlet. Beyond this basic function, models with surge protection or suppressors safeguard your electronics against overvoltage, whether caused by lightning or fluctuations in the power grid. Essential for computers, TVs, hi-fi equipment, and sensitive appliances. Learn more
Understanding the different types of power strips
A standard power strip simply multiplies the number of outlets. It’s suitable for less sensitive devices like a lamp or a clock radio. For valuable electronics, it’s better to choose appropriate protection.
Surge-protected power strips guard against major overvoltages caused by lightning during storms. Their effectiveness is measured in joules: the higher the value (a minimum of 900J is recommended), the better the protection. Some manufacturers even offer warranties covering connected devices in case of damage.
Surge suppressors protect against everyday voltage variations on the power grid: spikes when devices start up, transformer disturbances, grid outages. These repeated micro-surges shorten the lifespan of electronic circuits.
For comprehensive protection, some power strips combine surge protection and surge suppression in a single product, offering dual protection against both types of overvoltage.
Choosing according to your needs
The number of outlets (from 2 to 12 depending on the model) depends on your devices. Plan generously to avoid daisy-chaining multiple power strips, a dangerous practice that increases the risk of surges and fire.
Maximum capacity is expressed in watts and amperes. Most support 3500W and 16A, but always check that the total load of connected devices does not exceed this limit. For example: a computer consumes 200–400W, a 4K TV around 150–300W, a refrigerator 100–200W.
Additional features enhance usability: a master or individual switch to cut power without unplugging, USB ports to charge smartphones and tablets, mandatory child protection under European standards, and a cable from 1 to 5 meters depending on placement.
Formats and configurations
Plug-in adapters (double, triple, quadruple outlets) connect directly to a wall socket. Compact, they’re suitable for occasional needs.
Corded power strips offer more outlets and flexibility thanks to their cable. Some rotating models or those with spaced outlets make it easier to plug in bulky transformers.
Flat power strips slide behind furniture, while pop-up models integrate into kitchen countertops or desks.
Vertical tower power strips maximize the number of connections in a small footprint, ideal for workstations.
Specific applications
For the office and computing: choose a surge-protected power strip with multiple outlets for the tower, monitor, printer, and internet modem/router. Integrated USB ports simplify charging peripherals.
For audiovisual and home theater: surge protection safeguards the TV, set-top box, game console, and amplifier. The high-end audiophile market even offers filtered mains distribution blocks to optimize sound and image quality by eliminating electrical noise.
For appliances: protect washing machines, dishwashers, and refrigerators against voltage spikes that can damage their modern electronic circuits.
Safety and standards
A quality power strip meets NF and CE standards. Never connect multiple power strips in series. Replace a power strip whose surge protection indicator is off: it has absorbed a major surge and no longer provides protection.
Smart models, controllable from a smartphone via Wi-Fi, let you schedule power on and off remotely, integrating your devices into home automation scenarios.
