Does not work on cigarette lighter Renault Mégane and Trafic as too short. Do not the total length of the body of the charger that is in question but the length of the small metal cylinder at the end, responsible for the contact. I disassembled the charger, cracked the cylinder and welded a "extension". Since it works well and provided sufficient power. I use the jack marked "Ipad" for my Galaxy Note and it works very well (as my Galaxy Note needs at least 1,000 mA to operate with GPS).
