The case is supplied with alligator clips to connect it to the car battery, the charger outlet, cigarette lighter adapter, a USB / micro USB and a French leaflet which explains well how to use this product. Two USB ports allow you to charge your mobile devices and a flashlight function / hazard lamp is available. Tested on a Citroen C3, it works perfectly as all its other functions. This is a really handy multi-function tool that may save you late for work or a better paying towing your car in case of battery failure, I recommend!
