Enough sockets in every room, but too short cables of the end devices – almost everyone knows this problem.

If you are looking for a way to connect your devices at home or even outdoors without any problems, an extension cord can be the solution. Extension cords, as the name suggests, can extend power cables, giving you a much wider reach power distributor.

If you want to buy an extension cord, our extension cord comparison can help you find the best extension cord.

How to choose extension cord

You should definitely pay attention to the following criteria and characteristics. We have compiled these clearly for you:


Pay attention to the intended use before you decide on a particular extension cable.


When buying an extension cord, you should pay attention to the shape and color of the cord in addition to the length. Flat cables offer some advantages over round models. For example, they fit more easily in longitudinal joints and can be conveniently laid under carpets. The disadvantage here, however, is that if the extension cord is flat, they are often less long than round cords.


You should also consider the color of the extension cord. White and black extension cords are primarily represented on the market, but especially for outdoor areas, such as the garden, you should opt for flashier models – for example, in orange or red – to prevent tripping. There, the cable can be plugged into a garden socket.

Intended use

Cables suitable for outdoor use can be identified by their IP protection class. This consists of two code numbers and provides information about how well a device is protected against external influences and moisture. A cable with IP class 20, for example, is protected against foreign bodies and falling drops of water. However, since the cable is also exposed to spray water or rain outdoors, this protection would not be sufficient. Here you need a cable where the second code number is at least three. Better suited here, however, would be an extension cable with IP44.

Load capacity

Each extension cable has its own load capacity limit. If this is exceeded, uncontrolled heat development and short circuits or damage to the end device will occur. In principle, all available extension cords are suitable for operation with a mains voltage of 230 V. Models approved for up to 10 amps are suitable for household appliances. The current strength here is usually between 0.1 and 10 A. However, please note that this also depends on the device.


The equipment of an extension cable can include both a protective contact plug and a protective contact coupling. An additional protective contact (also called Schuko), can be defined as a kind of grounding, as it dissipates the electrical voltage in addition to the two contact pins when plugging in electrical consumers. We recommend using such a plug especially if you want to connect devices with a current of more than 2 amps to your extension cord. For household appliances, such as a blender or stove, a Euro plug, or Euro coupler, is usually sufficient. If the extension cord is to be used outside, we suggest you purchase a cord with a locking cap. As soon as the end-user is unplugged, this covers the cable coupling. So neither water nor dirt can get into the coupling housing

The types of extension cord

First, you should know the different types of extension cords in order to be able to better use the results from the extension cord test for yourself afterward. The following table gives you an overview of the types of extension cords.

Extension cable type Description
Simple extension cable
The basic function of the simple extension cord is to extend the range of an electrical outlet. It is available in different lengths (for example, extension cable 25m variant) and is divided into round and flat extension cables. Especially when the extension cords are flat, they are convenient because they have thinner insulation, which makes them more convenient to install.
Extension cord with power strip This extension cord consists of a plug for sockets and a strip with slots for multiple devices. This multiple socket usually provides from three to ten additional slots. In addition, this model is usually an extension cord with a switch. This toggle switch allows you to turn off the power strip when not in use, thus saving power.
Extension cord with cable reel This model consists of a plug for the socket and a cable reel (eg a cable reel or cable reel 50 m model) on which the cable can be rolled up. This large and robustly built extension cable is perfect for outdoor use.

If you want to enjoy more safety, you should definitely pay attention to the IP protection class and additional features, such as a grounding plug, when buying an extension cord. You should also factor the color of the cord into your decision, as more visibility can prevent tripping hazards. An extension cord with a power strip is a good solution if you want to connect multiple end devices indoors. However, only sufficiently protected cables are suitable for outdoor use.
