THERMOELECTRIC POWER
The PowerWatch requires a temperature dierential with the ambient
air to charge its internal battery. It generates more power when the air is
cooler and when your skin is warmer from being active. The chart below
shows how fast the PowerWatch charges its internal battery at dierent
air temperatures.
The PowerWatch charges its battery the fastest when you are active
(walking or running), and when the ambient temperature is below
80°F (26°C). Above 90°F (32°C), the PowerWatch cannot charge its
internal battery.
