To my Panasonic Lumix TZ1 supplied with a charger, so that I can charge the battery pack while the second battery is serving in the camera. Now there is only one factory charger, with which I can charge the battery in the camera. Since the offer of Star Bundle comes in handy. Maybe the charger is even better, because it is composed of two parts: an electrical part, the charger, and a mechanical part, the receiving tray, and contact for the specific battery of TZ 25. It works. But it makes me suspicious that only two contacts are used by the four that has the battery. Was not it, that the batteries contain any "intelligence" in order to make the charging process together with the power supply so that the maximum charge is reached - and the maximum battery life? Is here given away something, when the battery is not fully contacted? The barren manual says nothing about it. The thought-provoking to sad. The experience will have to show it ... yet everything is brand new. Also sadly it is true that Bundle Star is no evidence, for which other battery chargers would be available.
