Charging the Charging Dock
The Dock's built-in battery holds about 2 full charges for its pair of Trackers. That's up to 30 hours of training before the Dock itself needs power.
Connect a USB-C cable to the port on the Dock.
Plug the other end into a USB wall adapter (5V).
Leave it plugged in for about 1.5 hours for a full charge.
You can leave the Trackers in the Dock while it charges.
Tip: Charge the Dock before a trip, so it's ready to top up your Trackers while you're away.
