Like all heart rate monitoring technologies, accuracy is affected by physiology, location of device, and different movements. Learn more about wear during workouts.
Charge HR is sweat, rain and splash proof. However, the device is not swim proof or showerproof. With any wearable device, it’s best for your skin if the band stays dry and clean.
If the band gets wet or if you sweat in it, remove and completely dry the band before putting it back on. Clean the band with a mild soap-free cleanser like Cetaphil or Aquanil. Give your wrist a rest by taking the band off every now and then. Learn more.
Charge HR's wristband is made of a flexible, durable elastomer material similar to that used in many sports watches. Charge HR also has a surgical-grade stainless steel buckle.
We recommend charging your device every few days to ensure you are always tracking.
Charge HR syncs automatically and wirelessly to tablets, computers and 150+ leading iOS, Android and Windows smartphones using Bluetooth 4.0 wireless technology.
