There are no outlets at your personal campsites unless you rent one of our Bell Tents, Safari Tents, Moon Colony Powered Car Camping, or Powered RV packages that explicitly include this feature.
You will be happiest bringing a portable battery charger for your phone to use at your campsite and/or occasionally using your car to charge things (careful with your car battery though, and also be sure to watch where your car exhaust is pointing - carbon monoxide is no joke)
