Understanding Caravan Power Supplies

One of the worst things that can happen during a camping trip is getting caught in the dark. How can a holiday be fun if you don’t have access to simple pleasures such as light or even television? Most camp and caravan sites give you access to a mains electricity power supply. But caravans also have a built-in power source that’s called a leisure battery.

Mains power usually provides 240 volts that makes it easy to power fridges, hairdryers, and even caravan heating systems. Leisure batteries kick out 12-volts, which is ideally suited to 12 volt caravan televisions and other smaller devices that use less power. And if you’re smart with your power usage, you can get the most from your appliances with a 12V supply. With a 12V supply, you can power a kettle, water heater, or even run a laptop computer or some other electronic device like iPhones. 

Why Do I Need a 12 Volt Extension Lead?

Because 12V power sockets in caravans were used solely for televisions back in the day, most sockets are not in a viable place for your caravan’s other power supply needs. For example, you might need the socket in your kitchen to power some cooking appliances or to make a cup of tea. Caravan tire inflators also use a 12V power supply and are quite difficult to connect without an extension lead.

Do you need to store food on the road, so it doesn’t go off? If so, you will need to power an electric 12v cooler box. 12V power supplies are not usually enough to power refrigerators, so using an extension cable to hook up your cooler box is essential. These are just a few reasons why you need a 12V extension cable.
