Won't work in my car

I bought these so that I wouldn't have to replace all the charging cords when I got my Galaxy 9. I really like the little chain with the lobster-claw clasp on each of them that attaches them to the cord so you can unplug if you need to use the old-style charger plug, but it turns out they aren't very sturdy. Just unplugging the adapter was enough to break the chain off of the clasp. Good thing I bought the multi-pack, I guess... They work to charge the battery on my new phone, but I ran into a problem when I tried to use it with the cord in my car to connect to the SYNC system. It simply would not allow me to connect. So, I had to use the original Samsung cord in my car. When I need to connect to my computer, I have to bring the cord in from the car. A small inconvenience, but one that would be unnecessary if these functioned better, and honestly, I bought these to prevent the need to remember to carry one particular cord around with me everywhere.
