How to use

Insert the charger into the vehicle's 12–24 V socket and connect devices using appropriate USB-A or USB-C cables. The charger will negotiate the optimal charging profile with the connected device; if two devices are connected, available power is shared between ports according to device demand and protocol compatibility. Remove the charger from the socket when the vehicle is not in use for extended periods to avoid parasitic battery drain.

Usage recommendations

Use quality, data-capable USB cables that match the device’s charging requirements to achieve the best charging speed. Avoid using the charger in damp or excessively dusty environments, and unplug devices once fully charged to minimise unnecessary heat and extend battery lifetime.
