Some devices generally charge more slowly via wireless charging or reduce charging power more quickly.</li><li>Thermal management: When exposed to heat (e.g. sunlight, navigation use, running apps), many smartphones automatically reduce charging power to prevent overheating.</li><li>Power supply (power adapter / USB port): If the power source does not provide sufficient output, less energy is available at the Charging Module.</li><li>Simultaneous power consumption: Navigation, high screen brightness, mobile data, or music playback can consume so much energy that the device charges only slowly overall.</li></ul><h3 id="tips-for-improved-charging-performance-recommended">Tips for improved charging performance (recommended)</h3><ol><li>Use a suitable power source Use a power supply that supports Power Delivery (PD) or Quick Charge (QC 2.0 / 3.0 / 4.0) and provides sufficient output.

My smartphone charges too slowly when using the Charging Universal Phone Clamp. What can I do?

Yes, to a small extent. If you connect the Charging Universal Phone Clamp directly to the motorcycle battery using the  Cable 12V DC , a small standby current may flow even after the smartphone has been removed and with the ignition switched off. Thi

Yes, to a small extent. If you connect the Charging Universal Phone Clamp directly to the motorcycle battery using the <a href="https://sp-connect.eu/collections/electronics/products/cable-12v-dc-plus">&#xA0;Cable 12V DC&#xA0;</a>, a small standby current may flow even after the smartphone has been removed and with the ignition switched off. This is due to the system design, as it does not have a separate on/off switch and remains permanently ready for operation.<h3 id="recommendation-connection-via-ignition-switched-power-recommended">Recommendation: Connection via ignition-switched power (recommended)</h3>To avoid power consumption when the motorcycle is switched off, we recommend connecting the Cable 12V DC via ignition-switched power:<ul><li>The power supply is automatically disconnected as soon as the ignition is turned off.</li><li>This helps protect the battery and ensures the system is optimally safeguarded when the motorcycle is parked.</li></ul>
