Shorepower is like getting electricity from a big box instead of a battery. When you go camping or take an RV trip, you usually have to use a battery to get electricity for your lights and other gadgets. But if you can plug into the big box (like the one at home), you can get more electricity and charge your battery faster. This big box is like a special plug at a campsite or dock that gives your camper or boat the power it needs to run things like air conditioning or a microwave. It's called shorepower because it's like getting power from the shore (or land) instead of from a battery onboard your vehicle. But you have to have special cords and connections to use shorepower safely, so it's important to know how to set it up correctly.
