Sits a little tight, a little shaky and often loses contact !! Is the contact through not working with sloping ceilings: Perhaps anyone who needs something for the cigarette lighter should first daily in this ... For me, the bottom is a plastic part, which tapers the last 5mm of the shaft to the contact. A Charger as this, which is worked down flat, so it has little chance to reach the contact in my cigarette permanently. I will therefore probably have to try out the solution with a thick dollop of solder on the tip of the metal pin ...
Performance of the particle: 5V / 1A (. Dominated with me only 0.8mm max out from the lighter.) The battery of an iPhone 3GS with running (navigation) Software (Trapster) is slowly filled, if the contact does not break off. So, the power delivered to me. No gripes that the device would not be compatible with iPhone 3GS and iPod classic 120 / 160GB.
SEE ALSO: tighter, better contact, but (only), the 500mA USB Car Charger from Kensington (Model Number: K38058EU) which is beveled at the top!
