The batteries are well charged, the device is not very warm. A 12V adapter cable for the cigarette lighter is attached. In the manual, however, to read: "Do not charge in the car or while driving" ... Huh? For what the 12V adapter for then thought that if you do not use in the car ...? The mechanical locking of the battery being charged is bad because the nose that will fix the battery is too shallow. That's why the best charger during the charging set horizontally. Especially the non-Sony batteries used by Subtel by me fall out by itself when the charger is anbehoben obliquely or even vertically. Probably why the warning "... while driving ..." ???
