# Charging Your JEM AirKey HD

## Connect the Dock to a Power Source <a href="#connect-the-dock-to-a-power-source" id="connect-the-dock-to-a-power-source"></a>

**What's the best place for the Charging Dock?**

If you primarily work at a desk, we recommend setting up your Dock on your desk, and placing your JEM on it while you work. When you leave your desk, you can take your JEM with you with the confidence that it is adequately charged. Otherwise, locate your Dock on your nightstand or bedside table, and place your JEM on it at night. Ultimately, the choice is yours.

**How long does JEM take to charge? How long does the battery charge last?**

When placed on the Dock, JEM charges rapidly at first, and then slowly until it reaches full charge. JEM typically reaches full charge after a few hours on the Dock. A fully charged JEM should provide 2-3 days of service during normal use
