Unlock Your RAM 1500’s Potential: Switching 12V Outlet Power to Always On or Keyed

Last Updated on October 6, 2023 by Nick

How’s it going everyone? The RAM 1500 is a remarkable vehicle, and its 12V outlet adds to its charm. However, knowing how to switch it from Keyed to Always On, or vice versa, can be incredibly useful. Whether you’re looking to charge your devices while the engine is off or power your camping gear, understanding this process is crucial. So, let’s dive in.

Understanding the 12V Power Outlet Option

Before we begin the conversion process, it’s essential to understand the two options available: Keyed and Always On.

  • Keyed: This means the outlet only receives power when the ignition is on. It’s the default setting, ensuring that the outlet doesn’t drain your battery when the vehicle is not running.
  • Always On: In this configuration, the outlet provides a continuous supply of power, regardless of whether the engine is running or not. This is particularly useful for various applications, such as charging devices or running appliances when the vehicle is parked.

When to Choose Keyed or Always On

The choice between Keyed and Always On largely depends on your specific needs. Consider the following scenarios:

  • Keyed: Opt for this setting if you primarily use the outlet while driving to charge your devices or power GPS systems. It’s the safer option to prevent battery drain when the vehicle is not in use.
  • Always On: Choose this configuration if you need constant power for activities like camping, tailgating, or running electronic appliances when the engine is off.
