The campground I'm thinking of staying at has tenting spots, but they don't have power. I need to be able to charge my laptop, phone, and possibly a portable electric heater. They also offer RV spots with electric hookups in 30A or 15A. I'm not familiar with RV power, but from what I've read about RV hookups it would be a 3 prong (slanted style) outlet which means I'll need an adapter to convert it to a regular household outlet?
Will something like this work?
