1 to 4 DC Power Splitter Cable – 5.5 x 2.1mm & 5.5 x 2.5mm Female Barrel Connectors
Distribute DC power from one source to up to four compatible devices. The BiXPower CNT-1TO4SPLIT is a practical 4-way DC power distribution cable featuring two 5.5 x 2.1mm female barrel connectors and two 5.5 x 2.5mm female barrel connectors. Its bare-wire input makes it convenient for custom DC wiring, battery installations, and low-voltage power distribution projects.
The splitter features flexible 14AWG silicone-insulated input wires and 18AWG output connector cables, offering a compact solution for connecting multiple DC-powered devices to a common power supply.

How the 4-Way DC Power Splitter Works
This passive DC splitter distributes the input power across four barrel connector outputs. All four outputs share the same input voltage; the cable does not regulate, boost, reduce, or independently control the voltage.
For example, when connected to a suitable 12V DC power supply, the outputs provide the same nominal 12V input voltage, subject to wiring voltage drop. When connected to a suitable 24V DC source, the outputs carry the corresponding nominal 24V.
Important: The combined current drawn by all connected devices must remain within the ratings of the power source, the splitter assembly, and each output branch. A verified maximum current rating for this splitter has not been published on the product page.

Typical Applications
- DC battery power distribution: Connect several compatible low-voltage devices to one appropriately rated battery system.
- Security and CCTV installations: Distribute DC power to compatible cameras or accessories using matching barrel connectors.
- LED lighting projects: Connect multiple compatible DC LED devices to one power source.
- Electronics and DIY projects: Create convenient multi-output DC power wiring.
- Portable equipment: Simplify DC connections in custom portable power setups.
- Laboratory and testing: Provide multiple same-voltage DC connection points from a suitable power source.
5.5 x 2.1mm vs. 5.5 x 2.5mm DC Connectors
Both barrel connector sizes have a 5.5mm outside diameter, but their inner contact dimensions differ. The 5.5 x 2.1mm connector is intended for compatible 2.1mm center-pin plugs, while the 5.5 x 2.5mm connector is intended for compatible 2.5mm center-pin plugs.
Although the connectors look similar, using the correct size is important for a reliable electrical connection. Always check your device's DC plug dimensions, voltage requirements, and polarity before connecting.
Installation & Safety Notes
- Verify the input voltage matches the voltage required by every connected device.
- Confirm positive and negative polarity before applying power. Do not assume connector polarity without testing.
- Use an appropriately rated, protected DC power source.
- Ensure the total current demand does not exceed the power supply or splitter cable ratings.
- Check the current requirement of each individual output device.
- Insulate and secure all bare-wire connections to prevent shorts.
- This splitter does not provide independent voltage regulation, power isolation, or individual output switching.
- Do not connect incompatible power supplies to the output connectors.
Frequently Asked Questions
Q: Can this splitter power four devices simultaneously?
Yes, provided all devices require the same input voltage and the total current demand is within the ratings of the power source and cable assembly.
Q: Can I use this cable with a 12V or 24V battery?
The cable is a passive splitter and does not change voltage. It may be used in a properly designed DC system if the voltage, current, connector, insulation, and safety requirements are satisfied. Confirm the assembly's ratings before use.
Q: Are all four output connectors the same size?
No. Two outputs are 5.5 x 2.1mm female connectors and two are 5.5 x 2.5mm female connectors.
Q: Does the splitter convert voltage?
No. It distributes the supplied DC voltage without voltage conversion or regulation.
Q: Does this cable include a power adapter?
No. This listing is for the DC splitter cable. A compatible DC power supply or battery connection is required.
Q: Can I use only one or two of the four outputs?
Yes. Unused connectors may remain disconnected, provided they are protected from accidental contact or short circuits.
