How Heated Vests Work

Technology and Working of a Heated Vest

Heating elements such as carbon fiber sewn into the fabric, a rechargeable or disposable battery, and a temperature controller to regulate the heat output are the three main components of the cheated vest.

When the power switch on the heated vest is switched on, an electrical current flows from the battery to the heating components. When the heating components are activated, they warm the vest's material. This assists in warming the body and maintaining comfort during chilly conditions.

The size and length of the heating components in a heated vest affect how much warmth they produce. The quantity of current that flows through the heating components is also a factor. The temperature controller gives users the ability to adjust the amount of heat produced to meet their needs.
