Although it is intended to provide 1200mA, the operation with a Samsung Galaxy S Plus is limited. When navigation software, Bluetooth (for connecting to the car kit) and UMTS data transmission (for the latest traffic information to navigation) are turned on simultaneously and the display brightness is set to fix 50%, to approximately 1.5 to 2 hours, the power is not enough more from, the battery is low, the phone cuts forced the Bluetooth function and drives the display brightness down to "minimum", at least not to keep the navigation function ready (because someone in Korea but actually thought along time :-)
Original Samsung car charger adapter supply according to product description only 700 mA, and at a significantly larger housing. That is an original Samsung adapter the problem described here will not solve, but rather worsen. That is why I give this adapter here despite the limitation, the 4 stars. The review is therefore to look at relative and not absolute.
My tip: just get away for longer motorway journeys, the navigation software or the display when not in use must be included in every kilometer. Then, the battery time to recover.
