To fully charge, plug your Battery Pack into the Micro USB for 90-120 minutes.
NOTE: The Battery Pack contains LEDs (Light Emitting Diodes) which will indicate when the pack is fully charged. A fully charged Battery Pack's LED will change from red to green.
Reminder: While your WHOOP strap IS waterproof, your Battery Pack is NOT. Do NOT wear your Battery Pack in the water or shower.
