You'll be fine with your coffee machine. If you have any doubts, the MOST that will happen is, if you pull too much power and exceed your camper's 30 amp or 50 amp limit, the main breaker in the camper OR the breaker at the campground electric pedestal will pop. If that happens, simply turn something off (like your air conditioner or electric hair dryer or microwave), reset the popped breaker and make your coffee. No damage, using more power than you have available will just result in a popped breaker. If this happens, you'll figure out real fast what electric components can be used at the same time and which ones draw too much to be used with others. Bring it along and enjoy your coffee. (tip: If you air conditioner is turned off when you make coffee, chances are, you'll have ample power for your coffee machine.)
