First went to the company web page which was almost totally unusable; among other problems the links didn't work. Contacted the company by phone and that wasn't any more productive. Tried to order a cigarette lighter, 12 volt power supply for a IC-2TH, and all the person on the other end could ask is about the current battery pack. Never was able to get across to her that I didn't want another battery pack. As I have heard the product I tried to buy is quite good, I will try again someday to place the order.
