I purchased the charger when i purchased my hpx300. It stopped working and was sent for repair, replaced fuse and updated board.Two years later stopped working again. sent in for repair and then told " no longer stock parts to repair do i want it back or like to have us discard" $550 dosnt come easy for me and was not expecting that type of responce from a company with the repuation of AB the item is still being sold so does one purchase equipment assuming it wont be repairable especially a vital piece of gear seeing it not only charges battery but is my power source as well
