USB charger for motorcycle mounts Integrate the motorcycle USB charger seamlessly into any Quad Lock motorcycle mount. The charger is simply placed under the head of the Quad Lock bracket, so that the USB power supply is possible without a long charging cable. The 1.5 m long SAE connection cable and 20 cm SAE to the battery ring connections allow you to connect the device directly to your battery connection or an existing SAE port. The charger draws zero current when not in use, so there is no risk of draining your battery.
