Here is the model I bought - Ravpower PB14. I have used it many times with my KC-110 and have powered my ham transceivers using it as well. It is an amazing battery. My friend the guitar man says he loves this battery for the length of time he can run his KC-110's on it. Here is the RP-PB14 and KC-110 discussion:
