Power Strip Buying Guide: Choose the Right One and Avoid Pitfalls

A power strip, a trivial purchase? Not so fast. We've all known the frustration of bulky chargers blocking adjacent outlets, underpowered USB ports that take forever to charge a smartphone, or worse, a low-end model that fries our precious devices. Choosing the right power strip isn't just about the number of outlets. It's a matter of convenience, safety, and longevity.

To ensure you don't regret your purchase, here are the 3 pitfalls to avoid at all costs:

  1. The Illusion of Outlet Quantity: A 6-outlet power strip that can only fit 3 chargers? It's a classic scenario caused by poorly spaced outlets. The AC adapters for our laptops and other devices then become an impossible game of Tetris.
  2. Underpowered USB Ports: A USB power strip seems like a great idea! Except when its ports sluggishly share a mere 1A or 2.1A. The result: excruciatingly slow charging, completely unsuitable for modern smartphones and tablets that need plenty of juice to power up efficiently.
  3. Confusion About Protection: Be careful, a simple on/off switch or a circuit breaker doesn't turn your power strip into a surge protector power strip. The former cuts power during an overload (too many devices plugged in), whereas a surge protector is the only thing that can absorb a sudden voltage spike from the grid and save your devices.

The Technical Specs That Make All the Difference

For a smart purchase, forget about design for a moment. It's the technical specifications that guarantee performance and safety.

Maximum Wattage and Cable Gauge: Safety First

The ability of a power strip or an extension cord to safely power your devices depends directly on its cable's cross-section (or gauge). This information is usually indicated in a format like 3G1.5?mm? or 3G1?mm?.

  • A 3G1.5?mm? cable is the standard for typical home use, capable of handling a maximum load of approximately 3,680?W. This is what you need for plugging in a computer, monitor, and other office peripherals.
  • A 3G1?mm? cable is generally limited to 2,300?W. It's suitable for less power-hungry devices.

For a cable reel, it is imperative to fully unwind the cord before using high-power devices. A coiled cable can overheat and create a fire hazard, even when operating well below its rated maximum wattage.

Device Protection: Surge Protectors, Overloads, and Switches

A quick glossary of protection features is essential to safeguard your equipment.

  • Overload Protection: Most quality power strips are equipped with a circuit breaker. If the total power draw exceeds the strip's capacity, the current is cut off to prevent overheating.
  • Surge Protection: A surge protector power strip integrates components (varistors) that absorb dangerous voltage spikes (caused by lightning or grid fluctuations). This is an indispensable safety feature for televisions, computers, and hi-fi equipment.
  • Power Strip with Switch: Whether it's a master switch for all outlets or individual ones for each, a switch allows you to cut power to devices in standby mode, thus saving energy and providing an extra layer of safety.

Design and Use Cases: From Home to the Job Site

The environment of use dictates the type of product to choose.

  • Indoor Use: A standard power block with an H05VV-F type cable is sufficient. For tight spaces behind furniture, models with a flat plug are a very practical solution.
  • Outdoor or Damp Environment Use: For a workshop, garage, or garden, opt for a waterproof extension cord or a power strip with an IP44 rating. This standard guarantees protection against water splashes. The cable should be more robust, such as an H07RN-F type, to withstand abrasion and outdoor conditions. A job site power strip will meet these durability requirements.

Power Strips: Your Questions, Our Answers

What's the difference between a surge protector and a simple power strip?

A standard power strip, even one with a switch, merely cuts off the power in case of an overload (too many devices plugged in). A surge protector power strip, on the other hand, integrates components capable of absorbing violent voltage spikes from the grid. It's the only thing that can save your valuable devices (computer, TV, gaming console, etc.) from certain death in the event of a power surge.

Can you plug multiple power strips into each other?

Never! Plugging power strips into one another in a series (also known as "daisy-chaining") is strictly forbidden and extremely dangerous. This practice creates a major risk of overloading the first power strip and the wall outlet, leading to a significant risk of overheating and fire. It is a practice prohibited by electrical safety codes worldwide, such as the NF C 15-100 standard in France.

How can I check the maximum wattage my power strip can handle?

The maximum wattage, expressed in watts (W), must be indicated on the product, often stamped on the casing (e.g., "Max 3,680W"). The calculation is simple: add up the wattage of all the devices you plan to plug in and ensure the total does not exceed this limit. The wattage of each device is listed on its label or in its user manual.
