the power cable is great for in the boat to keep you from using up you batteries. there is also a cable that I have that has the computer data plugin and a 12 volt adapter that you can plugin to a cigarette lighter style plugin that alot of boats have on them or you can easly install a 12 volt plugin if you dont have one. it will save several dollars over time.
