Setup Electrical System and Tool Organization

OK. So, these rubber ties were a great solution. They don't fall out on turns. I already checked. I moved it to my home. The drawers keep them straight. They don't fly either. Perfectly. I am very pleased with the result. Now I have more and more tools here, and we are gradually getting organized. Today we will deal with electricity . So, here's the main idea. Here is my big battery.

And on top of this battery, I have solar panels. They work like this: they simply unfold . And here is my cable. So the work process will be simple: unfold it, throw it on the roof. Boom. Now the solar panels are charging our system. These panels and battery are needed to charge the batteries, the lights in the trailer, and one more secret thing that I will be happy to show you. But usually, if I'm working in a house where there's electricity, I just plug an extension cord into the trailer. But we'll make it even cooler . This is a cable for campers that supplies power to the trailer without unnecessary wires. Problem. He is too fat. The gap between this place and that place is too big.

So, our power comes from the house to the trailer, to the power supply. The power supply also receives energy from solar panels on the roof. And I have two more outlets coming out here from the power that comes from the house. And I can power my
