Power Strip Buyer’s Guide: How to Choose the Right One
A shortage of outlets is a common problem in many households. A good power strip, also known as a socket strip, seems like a simple solution. However, there are pitfalls that can lead you to purchase an unsafe or impractical product. Going for the cheapest option can be a costly mistake, with risks of short circuits or even fire.
Before you make a choice, it's important to know the most common missteps. This will prevent you from wasting money on a product that doesn't meet your needs or, worse, poses a safety hazard.
- Pitfall 1: The "everything-fits" illusion. Many cheap power strips have sockets placed too close together. As soon as you plug in one or two larger adapters, the adjacent outlets become unusable.
- Pitfall 2: Ignoring the cable gauge. A thin, flimsy cable can overheat when multiple devices are connected, especially if one of them has a high power consumption. This is a direct safety risk.
- Pitfall 3: Insufficient power capacity. Not every power strip can handle the combined load of a kettle, a computer, and a phone charger simultaneously. Exceeding the maximum power rating (expressed in Watts) leads to overload, which can trip a fuse or damage the power strip.
What to Look For to Make a Safe and Practical Purchase
To avoid these pitfalls, there are a few objective specifications you can check. These details determine the safety and usability of a power strip or extension cord.
1. Safety Marks and Grounding
A safe power strip is equipped with the proper certifications. Pay attention to the following points:
- CE Marking: This indicates that the product complies with European safety standards. Never buy a power strip without this mark.
- Grounded Plug: A power strip with grounding (two metal clips on the side) is essential for safely connecting appliances with a metal casing, such as a computer or washing machine.
- Child Safety Shutters: Most modern power strips have internal shutters that block the openings. They only open when pressure is applied simultaneously with both pins of a plug, preventing children from inserting objects into the socket.
2. Cable Gauge and Length
The cable's specifications are crucial for safety, especially with higher power consumption.
- Cable Gauge: The cable often displays a code like H05VV-F 3G1.5mm?. Here,
3Gstands for three cores (including the ground wire) and1.5mm?for the thickness of the copper cores. A gauge of 1.5mm? is the standard for power strips rated for up to 3680W. Thicker cables heat up less quickly and are safer. - Cable Length: Choose a length that suits your situation. A cable that's too short is inconvenient, while one that's too long can become a tripping hazard. Popular lengths like a 3-meter power strip or a 5-meter power strip often provide enough flexibility for home or office use. For greater distances in a workshop, a cable reel is a better solution.
3. Extra Features
Modern power strips offer more than just extra sockets. Consider which features would be useful for you:
- Power strip with a switch: A master switch allows you to turn off all connected devices at once, which helps combat standby power consumption. An individually switched power strip gives you control over each outlet.
- Power strip with USB: Ideal for charging phones and tablets without separate adapters. A power strip with USB-C is useful for newer devices and often supports faster charging (Power Delivery).
- Surge protection: This protects sensitive electronics like computers and televisions from damage caused by power surges, for example, from a nearby lightning strike.
- Wall-mountable power strip: Many models have mounting holes on the back, allowing you to neatly attach the power strip to a wall or under a desk.

How many devices can I safely plug into one power strip?
It's not about the number of devices, but the total power consumption (wattage). Check the maximum power rating of the power strip, which is typically 3680 Watts for a 16 Amp model. Add up the wattage of the devices you want to connect. Avoid plugging multiple high-consumption appliances (like a kettle, electric heater, or washing machine) into a single power strip.
What is the difference between a power strip with and without surge protection?
A standard power strip only distributes power. A model with surge protection has an extra circuit that protects connected devices from damage caused by sudden voltage spikes. This is recommended for valuable and sensitive electronics, such as a computer, TV, or sound system.
Can I plug an extension cord into another extension cord?
No, this is strongly discouraged. This practice, also known as 'daisy-chaining', significantly increases the risk of overload and fire. Instead, use a single extension cord or cable reel with the appropriate length and sufficient outlets for your needs.
