News & Reviews:   Reserve Strap

The Reserve Strap is a wristband made to extend Apple Watch battery life, from barely a day to almost a week long of usage. The wristband uses the Watch accessory port, to charge the battery while also acting as the wristband. However, unfortunately, Apple decided to close the port by making changes in the External Accessory Protocol on their WatchOS version 2.0.1 update, which has disabled Reserve Strap functionality completely.
