<p><strong>Description:</strong></p>
<p>The <code>onchargerconnected</code> property is an event handler for the event of when the charger is plugged to or unplugged from the device.</p>
<p>Since the event is fired off much faster than the value is updated, it is recommended to read the value after a small delay. See example code for illustration.</p>
<p>For more general information on power consumption and widgets, see <a href="GUID-159FCC18-2C9D-49F0-BAC1-DFEAADCF1D89.html#GUID-159FCC18-2C9D-49F0-BAC1-DFEAADCF1D89">Saving battery time</a>.</p>
