Short answer: Yes, but it is not recommended.

Speaker cables and household power cords are both electrical cables that can be used to transmit current. However, there are some differences in their design, intended use, and safety requirements.

Speaker Cables

Speaker cables are primarily used to transmit audio signals. Their characteristics are as follows:

Low resistance to reduce signal transmission loss.

Wide frequency response range to meet the transmission requirements of different audio signals.

Good shielding effect to reduce external interference.

Household Power Cords 

Household power cords are primarily used to transmit electrical energy. Their characteristics are as follows:

Strong current carrying capacity to meet the power consumption requirements of household appliances.

Good insulation performance to ensure safe use.

Good performance in high-temperature resistance, corrosion resistance, wear resistance, etc. to extend the service life.

Risks of Using Speaker Cables as Household Power Cords

Speaker cables are usually only designed for audio signal transmission, and their current carrying capacity and insulation performance may not meet the requirements of household appliances. If speaker cables are used as household power cords, there are the following risks:

Speaker cables may overheat and even cause fire due to overload.

The insulation of the speaker cable may be damaged due to aging or breakage, causing electric shock accidents.

Recommendations

For safety reasons, it is not recommended to use speaker cables as household power cords. If you need to use them temporarily, please pay attention to the following:

Choose speaker cables with a larger cross-sectional area to improve the current carrying capacity.

Avoid using them for a long time, and pay attention to the temperature change of the speaker cables during use.

Regularly check the insulation of the speaker cables for damage. If there is any damage, replace it immediately.

Alternatives

If you need to replace a household power cord, it is recommended to choose a qualified product that meets national standards. In addition, you can also consider the following alternatives:

Use a professional power cord extension.

Use a multi-function socket to increase the number of power sockets.
