your Charge HR can do!
Press the button to see your daily activity stats and real time heart rate.
Charge HR normally lasts about 5 days and will take 1-2 hours to charge.
After activities where you sweat or your wrist gets wet, clean and completely dry both your wrist and the band before re-wearing.
Clean your Charge HR regularly with a mild soap-free cleanser like Cetaphil or Aquanil.
If you notice skin irritation, please remove the device. For more information, read the full Wear and Care Tips.
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.
To track heart rate, your band should lay flat, a finger's width above your wrist bone.
For better readings during exercise, wear the band higher up on your wrist‐about 2-3 finger widths above your wrist bone.
Charge HR tracks your heart rate all day and during exercise.
