USB-A | USB-C grounding cable with cylindrical socket - 2 m

The USB earthing cable with cylindrical socket allows you to earth all your devices with a USB port (modem/box, laptop, TV, iphone, ipad etc.) and protect you from the electric fields they emit.

Modems and set-top boxes are not earthed, so they generate a large electric field, which has many effects on the body: stress, irritability, nervousness, headaches, hyperactivity, difficulty concentrating, sleep problems, etc.

This USB earthing cable effectively neutralises them and at the same time eliminates the electric fields emitted by corded telephones connected to the box. Sensitive people are no longer disturbed when they make calls.

It also eliminates the electric fields emitted by a laptop without an earthed plug (2-pole, flat plug) and any other device without an earthed plug but with a USB connection (television, for example).

Reduced footprint

Its advantage

Electric fields are picked up by the USB connector and evacuated via the cylindrical socket, which is connected to the earth terminal of your wall socket (see photo). This leaves the socket available for plugging in a cable that is not earthed (2-pole flat plug). 

The diameter of this socket means it can also be fitted to the metal fins of schuko sockets. You can therefore connect it to a Danell Biologa shielded power strip.

Caution! This cable must be plugged into an earthed wall socket! 

Before earthing, check that the socket you want to use is earthed! (with a Peakmeter PM6860DR earth tester or an earth tester such as Catohm DT300, Tohm-E or 9052SI).

Precautions for use

As this cable is connected to the electrical earth, it is important to check that it is present and of good quality. 

You can check its presence using the Earthing tester and its quality using an earthing meter such as the Tohm-E or the Catohm DT-300.

According to the NF C15-100 standard, the resistance of the earth connection must not exceed 100 Ohms. However, in order to neutralise electric fields and parasitic voltages, we recommend an earth resistance of 50 Ohms or less. 

If in doubt, contact an electrician.
