Your universal DC connection cable for flexible power supply
You know the problem: In your motorhome, on your boat, or in your smart home, you want to connect your devices such as 4G / 5G Routers, IP Cameras, or LED strips directly and cleanly to a 12V or 24V power source. However, cutting original cables is often not an option – think warranty and messy solutions. This is where our DC connection cable 12V comes in! With 1.5m length and a 5.5x2.1mm barrel connector on one side and already stripped, tinned ends on the other, it offers you the ideal basis for any permanent installation. No more makeshift solutions, bring on professional and secure power supply!
Secure installation that lasts – thanks to tinned ends
We know how important a stable connection is, especially in environments where vibrations or moisture can play a role. That's why the open cable ends of our 1.5m open-end cable are already stripped and tinned. This has a huge advantage: when screwing into terminals, such as in your fuse box or a terminal block, the individual strands do not fray. This ensures a permanently secure contact, minimizes the risk of loose contacts, and significantly increases the longevity of your installation. Whether you are looking for a vehicle DC connection cable or realizing a DIY DC power supply – you can rely on this cable.
More than just 12V: Ready for 24V systems and broad compatibility
Even though many of our customers use the cable for 12V on-board power supply connection applications, it is universally applicable and also perfectly suited for 24V systems in campers, yachts, or trucks. The standardized 5.5x2.1mm barrel connector is a true all-rounder and fits a variety of devices. From WiFi Routers models like ALFA Network or Teltonika to surveillance cameras and LED light strips – this cable is your flexible partner. Do you want to connect a power supply without a suitable barrel connector to your device? No problem, simply use it as an adapter and connect the open ends to your power supply.
Your advantages at a glance: Smartly connect, preserve warranty
With this universal DC connection cable, you not only protect your devices but also their warranty. Instead of cutting the original cables of your power supplies, you simply use this pre-assembled cable for your permanent installation. This is particularly practical for devices where you might want to use the original power supply elsewhere later. The 1.5 meters length also gives you enough leeway for clean routing. The already stripped and tinned ends are a detail that is often overlooked but is crucial for the reliability and longevity of your connection in demanding environments. A small detail with a big impact!

Frequently Asked Questions (FAQ)
What is a DC connection cable with an open end used for?
A DC connection cable with an open end is used to connect electronic devices directly to a power source such as a battery, a fuse box, or a distribution box, especially in vehicles (camper van, boat, truck) or for DIY projects where a standard plug is not required.
Which devices can I connect with a 5.5/2.1mm DC cable?
With a 5.5/2.1mm DC cable, you can connect a variety of 12V devices, including routers (e.g., ALFA, Teltonika, Huawei), surveillance cameras, LED light strips, and other low-voltage electronics.
Is this cable also suitable for 24V systems?
Yes, this DC connection cable is universally suitable for 12V and 24V systems in camper vans, yachts, trucks, or for DIY projects.
What does "open end" mean for a connection cable?
"Open end" means that the cable has no plug on one side, but rather stripped and often tinned wire ends that can be inserted directly into screw terminals, terminal blocks, or other connection blocks.
Can I use this cable to connect a power supply without a barrel connector to my device?
Yes, if your power supply does not have a matching barrel jack or if you want to connect a power supply with an open end to a device with a 5.5/2.1mm barrel connector, this cable can serve as an adapter by connecting the open ends of the cable to the power supply and plugging the barrel connector into your device.
What advantages do tinned cable ends offer during installation?
Tinned cable ends offer the advantage that the individual strands do not fray when secured in screw terminals. This ensures a more stable and reliable electrical connection and reduces the risk of loose connections or short circuits.
