Your clever helper for every DC connection
You know the problem: you want to connect your LED Installation Adapter, a surveillance camera, or your WLAN Router, but the power supply has a round DC plug and you only have open cable ends available. This is exactly where our practical DC Barrel Jack to Screw Terminal Adapter comes in! It makes your life easier, because with it you can establish a stable connection in seconds – completely without soldering. Simply strip, clamp, screw tight, done!
Flexibility that inspires: From 12V to 24V
This adapter is a true multi-talent. Whether you need a 12V DC Adapter for your RV, boat, or car, or are looking for a 24V DC Adapter solution for your LED lighting – this adapter is compatible. It is the perfect choice for anyone who needs a reliable Power Supply Adapter without complicated installations. Especially for hobbyists and makers who want to quickly develop prototypes or realize temporary setups, the solderless installation offers enormous advantages. This saves valuable time and allows you to react flexibly to changes.
Safe and simple: Reverse polarity is a thing of the past
Installation is child's play and absolutely safe. The screw terminal 5.5x2.1mm is clearly marked with Plus (+) and Minus (-). This minimizes the source of error during installation and ensures that you maintain the correct polarity. This is particularly important to avoid damage to your devices. And another clever tip: If you have a power supply with a permanently connected cable and it is damaged, you can connect a new standard DC cable with this adapter without opening the original power supply. This potentially preserves the warranty of your power supply!
Versatile applications for your projects
This solderless DC plug adapter is not only ideal for home use but also for more demanding environments. It is perfect for use in the Yacht / Camper / Motorhome area, where you often need to quickly and easily connect devices to the onboard electronics. It also offers a robust and flexible connection option for IP Cameras or other surveillance systems. With the 5.5 x 2.1 mm DC plug, you have a universal solution for many of your electronics projects at hand.

Frequently Asked Questions (FAQ)
What is a DC barrel jack to screw terminal adapter used for?
This adapter is used to quickly and solder-free connect open cable ends (strands) to devices with a standardized 5.5 x 2.1 mm DC barrel jack connection, for example, for power supplies, LED lighting, or surveillance cameras.
Do I need a soldering iron to use this adapter?
No, the adapter is designed for solder-free assembly. The cables are simply stripped, inserted into the screw terminals, and tightened.
Which voltages are compatible with this DC adapter?
The adapter is versatile and compatible with 12V and 24V installations, making it ideal for applications in cars, boats, or LED projects.
How do I connect the cables correctly to avoid reverse polarity?
The adapter's screw terminals are clearly marked with Plus (+) and Minus (-) to ensure correct polarity during connection and prevent reverse polarity.
Can I maintain the warranty of my power supply with this adapter if I need to replace a cable?
Yes, instead of cutting the original cable of a power supply, you can create a suitable connection cable yourself with this adapter, potentially maintaining the power supply's warranty.
Is the adapter suitable for use in humid environments?
It is recommended not to use the adapter in humid or wet environments, as this could compromise electrical safety.
