I absolutely agree with TT, the little adapter has a bad tendency to overheat and sometimes melt, not something you want to happen! Get a good quality dogbone adapter like the one from Amazon. I also carry the 30 to 15 dogbone so I can keep batteries charged at home. Plug both adapters in a chain then you can use 15 amp, won't run AC but will allow you to precool your fridge.
