LG uses a proprietary connector for the charger. I misplaced my charger and tried to replace it but I was not able to find a replacement charger with the correct connector. I bought another headset instead (Motorola) with a universal mini connector. While the LG headset performed satisfactorily (not perfectly, by any means), I would not recommend it because of the proprietary connector. There are plenty of good headsets that use a universal connector allowing you to use many different chargers. Now I carry one plug-in and one car charger and use them for both my phone and headset. Anybody need an LG HBM 730 headset - cheap (charger not included)?[Footnote: for some reason, Amazon has 3 separate listings for the LG HBM 730]
