It plugs into the cigarette lighter simply and connects two appareils.J'ai enjoyed the presence of small balls on the end, two on each side, as they allow to drive and remove the charging cradle effort. In particular, I tested on my smartphone and I admit I thought it was awfully handy in case of intensive use of the device or when you have no time to do a load at home.
A blue light turns on when the car is started. By cons, once stopped, the charger also stops. Similarly, if you connect two devices, it is no longer possible to see this little light. It's a shame. However, the loading time appears equivalent to that of a charger used in the sector.
The notice of explanation is limited to the minimum without French version ... that said, given the simplicity of use, it is not really necessary. A little regret about the fact that this product is made in China.
In conclusion, I would say this is a nice product, see course over time, and very practical.
