Why I Use a Waterproof 12V Power Distribution Block

As an avid camper and overlander, I’ve learned the hard way that a good power distribution block is essential for keeping my electronics running safely and efficiently.

A power distribution block is a device that allows you to connect multiple 12V devices to a single power source, such as a car battery. This is important for several reasons.

First, it helps to prevent overloading your battery. When you connect multiple devices directly to your battery, you run the risk of drawing too much power and causing the battery to overheat or even fail. A power distribution block allows you to distribute the load evenly across multiple circuits, which helps to prevent this from happening.

Second, a power distribution block can help to protect your devices from electrical surges. When you connect a device directly to your battery, you’re exposing it to the full voltage of the battery. This can damage sensitive electronics if there’s a sudden spike in voltage. A power distribution block has built-in surge protection, which helps to protect your devices from damage.

Finally, a power distribution block can make it easier to manage your power system. With a single central location to connect all of your devices, you can easily see which devices are drawing power and how much power they’re using. This can help you to avoid overloading your system and to troubleshoot any problems that you might have.

I’ve been using a waterproof 12V power distribution block for years now, and I can’t imagine going back to a system without one. It’s one of the most important pieces of gear in my overlanding kit, and I highly recommend it to anyone who spends a lot of time in the outdoors.
