Not a good idea – If you have three devices, you should never just unplug them

Standby mode is not the best way to save energy. It is definitely worth unplugging the device completely sometimes.

What many people don't know, however, is that the type of electrical appliance is crucial. Some people have problems when their power supply is cut off.

Unplug or switch off the device? One difference is crucial

But whether you pull the plug or use the switch to deactivate it does make a difference. At least for your wallet.

This is because many electrical devices continue to consume electricity even when they are switched off. These include televisions, radios, LCD monitors and cordless telephones. Their red LEDs show very clearly that energy is still flowing after they have been switched off. This is known as “phantom charging”.

You can find five tips for effectively saving electricity in your home in the video above.

If you want to save electricity and money, it may seem worthwhile to unplug your appliances instead of just turning them off. However, the order in which you do this is important.

To avoid damage, you should always use the switch first and then the plug.

You should never unplug these three electrical devices

However, not all electrical devices can tolerate being completely disconnected from the power supply. This can be due to a number of different things. Sometimes it is due to the way they work, sometimes due to their programming. But the reasons for this are always obvious.

1. Printer (ink)

When it comes to electricity, inkjet printers are not a big deal. So it is not necessary to remove the power from the electrical device. However, there is a real problem that arises when the printer is not turned off using the power button, but is disconnected from the power supply.

When switched on, it is ready to print and the print head is not in idle mode. If the plug is then pulled out, the process remains paused without shutting down, as would be the case if the printer were switched off normally.

This is similar to a reset. This means that the inkjet printer restarts completely and assumes that the print head has not been used for a long time. So it is cleaned and uses a large amount of ink.

2. WLAN router

Being supplied with internet at all times is the advantage of constantly active FritzBoxes, Speedport devices, etc. It can be worthwhile to switch off the WLAN router at night, but only if no other important devices are connected to it.

If you use it to operate a landline phone, answering machine and/or smart home electrical devices, it is better not to unplug the router. These will then be unavailable or may even cause problems when the device is supplied with power again.

3. OLED TV

Modern TV sets such as OLED TVs are bothered when the power cord is pulled out. This is because the pixels are automatically updated in the background.

Regularly disconnecting from the power supply would improperly interrupt this process and could cause damage or impair image quality.

It is best to check with the manufacturer in advance whether you can switch off the electrical device using the power button or whether it is permitted to disconnect the power supply completely.
