Power strips: what they are and the different types available

In an increasingly connected world, the need to plug in multiple electrical devices at the same time has become an everyday occurrence. Power strips have evolved from being a simple accessory to becoming an essential tool in our homes, offices, and workspaces. But did you know that not all power strips are the same or offer the same features?

Below, we explain what a power strip is, the types available, and how to use them safely and efficiently.

What is a power strip?

A power strip is simply a device that allows you to connect several electrical appliances to a single power outlet. It consists of an elongated casing with multiple sockets, and usually includes a cable and plug for connection to the electricity supply.

Its main function is to increase the number of available outlets at a specific location, which is especially useful in areas where several devices need to be powered simultaneously: from computers and lamps to household appliances, chargers, games consoles and more.

Types of power strip

Although they all serve the same basic function of providing additional sockets, power strips can vary significantly in design, features and level of safety. The following are the most common types you can find on the market:

Simple power strips

As the name suggests, these are the most basic. They offer several power outlets without any additional features or protection systems. They are useful for temporary or low-demand applications, but are not recommended for sensitive equipment or continuous use, as they do not protect against power surges or overloads.

Power strips with surge protection

These include systems that protect your devices against sudden increases in voltage, such as those caused by storms, faults, or network outages. They are ideal for plugging in sensitive electronic equipment such as computers, televisions or routers. Additionally, they typically include indicator lights to show whether the protection is active or not.

Power strips with switch

They feature a main switch that allows all connected devices to be disconnected at once without having to unplug them. This helps to avoid standby power consumption*, the energy used whenever a device is plugged in, even if it is switched off, thus providing an extra layer of safety for the daily use of certain devices.

Adaptable or accessible power strips

They are designed with a rotating or modular format, making it easier to connect large plugs or plugs with unusual shapes without them interfering with each other. Many are designed for people with mobility issues or to maintain a tidy appearance in small spaces.

Multi-connection power strips

They go beyond the traditional socket, as they include USB, USB-C or even Ethernet ports, allowing you to charge devices such as mobile phones, tablets or cameras directly. These power strips are perfect for digitalised homes, offices and co-working spaces.

Special power strips

In addition to all the types we’ve already mentioned, there are other kinds of power strips designed with specific features to meet particular needs:

• Power strips with timers, which switch on or off at predefined times.
• Outdoor models, with IP protection against moisture and dust.
• Mountable power strips, ideal for installation on walls, desks or technical racks.

How are electrical power strips used?

Using them may seem easy, but doing so correctly makes all the difference. The first thing to check is the maximum power rating supported by the power strip to avoid overloading. This information is usually printed on the casing or label.

Avoid connecting high-demand appliances such as ovens, heaters or washing machines. These devices must be connected directly to the mains, not to a power strip.

In addition, it is important not to 'daisy-chain' power strips, that is, not to connect one power strip to another to obtain more sockets. This practice increases the risk of overload and can cause serious electrical incidents.

Tips for using power strip safely and optimising energy

Here are some relevant recommendations to help you use your power strips responsibly:

• Select certified models bearing the CE mark and equipped with built-in protection systems.
• Switch off the power strip when not in use, especially if it has a switch. This reduces unnecessary consumption.
• Do not use damaged power strips, or those with frayed cables or broken casings. The electrical risk is very high.
• Distribute the load properly: do not connect all high-consumption devices to the same power strip.
• Place them away from sources of heat and humidity; the bathroom and kitchen are not ideal locations for continuous use.
• If you have pets or children, look for models with child safety features or protective covers on the sockets.

Power strips are a great ally, but like any tool, their correct use and appropriate selection make the difference between a safe and efficient installation and a source of problems. If you are considering upgrading your electrical system or improving your home's energy consumption, choosing the power strip that best suits your needs is a small but significant step towards smarter electricity use.
