Powerful Technology, Powered by You

The PowerWatch X offers a rugged build and added features upgraded over the original PowerWatch. Where most smartwatches require daily charging, the PowerWatch X is entirely independent of any external power sources other than the person who wears it. Track all your activities throughout a day to meet your fitness goals. Sync your fitness data to your phone or device easily through the Power Watch Companion app.

How much power can the PowerWatch generate?

The PowerWatch requires a temperature differential with the ambient air to charge its internal battery. It generates more power when the air is cooler. Also when your skin is warmer from being active.

What are thermoelectrics?

A thermoelectric is a device that converts heat to electricity. They have been used for decades in niche applications to power NASA satellites. MATRIX has developed a thermoelectric technology that is highly efficient and can convert low grade heat from a person's body to power a smartwatch. MATRIX not only has the most advanced thermoelectrics but the most efficient boost converter that is required to run the watch electronics.

What Technology Does PowerWatch Use?

The PowerWatch uses a thermoelectric generator (TEG) that senses body heat and converts it into energy. TEGs need to have a hot side and a cold side to operate. The hot side is the circular black aluminum plate on the back of the watch. The cold side is the entire metal bezel and body of the watch. The hot and cold sides are separated from each other by a layer of insulating thermoplastic.
