How Reserve Strap Works

  1. Reserve Strap will connect to the Apple Watch similar to Apple bands. It will slide in laterally then you’ll then push forward a small switch underneath the band to engage the accessory port connection to secure the Reserve Strap on the Watch.
  2. At your discretion simply press the power button once to initiate charging. You can use the Watch as normal while it charges.
  3. Once top-off charging is complete after 60-75 minutes, press the power button again to save the rest of Reserve Strap for another time. Or if you decide to leave Reserve Strap on, Apple Watch will use the Strap’s power to keep the Apple Watch at 100% power until the Reserve Strap is depleted.
  4. Reserve Strap uses a minimal LED indicator to let you know how much charge you have left. When you turn the charge on or plug it in, the LED will glow either green, yellow or red indicating a high, medium or low charge.
  5. Recharging the Reserve Strap and Apple Watch is incredibly easy. You can leave your Strap on the Watch and simply plug it in via micro USB. This will charge the Apple Watch and Reserve Strap at the same time!
