Dave hates products with built in charging that don't use a standard Micro USB connector. In this case the Panasonic Lumix LF1 with its stupid proprietary connector. Why in this day and age of attempted standardisation are companies still doing this? Dave also shows off a good example, the Sony NEX-5T that charges from standard Micro USB. http://amzn.to/1fNgi5l Forum: http://www.eevblog.com/forum/blog/eevblog-578-proprietary-connector-rant/ EEVblog Main Web Site: http://www.eevblog.com EEVblog Amazon Store: http://astore.amazon.com/eevblogstore-20 Donations: http://www.eevblog.com/donations/ Projects: http://www.eevblog.com/projects/ Electronics Info Wiki: http://www.eevblog.com/wiki/
