Quick Overview
The DIYables 1 to 4 DC Power Splitter distributes one DC supply to four devices. A 5.5 x 2.1mm female barrel jack accepts a standard DC adapter, and the cable fans out at a moulded junction block into four legs, each terminated with a 5.5 x 2.1mm male plug. Every connector is wired centre positive, so it drops into existing setups without any rewiring. The assembly measures 38cm (15 inches) overall, giving enough spread to reach four devices grouped in one area.
The four outputs are wired in parallel, which means each device sees the full source voltage while the currents all add together. Sizing the supply is therefore the main design step: a four-camera CCTV run or a four-section LED installation needs an adapter rated for the sum of all four loads, with headroom. Within that limit, one adapter and one outlet replace four of each, which is why these are common in surveillance installs, signage, and multi-board benches.
Ideal for powering several CCTV cameras from a central supply, feeding multiple LED strip sections, running a cluster of development boards on the bench, or consolidating any group of devices that share the same DC voltage. This listing includes 2 cables.
Key Features
- One Input, Four Outputs — A single female barrel jack feeds four 5.5 x 2.1mm male plugs from one supply
- 38cm Overall Length — 15 inches of reach across the four legs, enough to spread between grouped devices
- 5.5 x 2.1mm Throughout — Input and all four outputs use the same barrel size, matching most DC adapters
- Centre Positive Wiring — Every connector follows the standard polarity convention used by wall adapters
- Parallel Outputs — All four legs deliver the full source voltage for identical devices on one adapter
- Moulded Junction Block — The four-way split is enclosed in a branded moulded body that supports the cable
- Replaces Four Adapters — One supply and one outlet serve four devices, freeing power strip space
- No Wiring or Soldering — Plug-and-play connectors with nothing to strip, splice, or terminate
- Flexible Cable Legs — Slim insulation routes neatly behind cameras, along strip runs, or inside enclosures
- 2 Pack — Two splitter cables, covering up to eight devices across two supplies

※ NOTE THAT:
All four outputs are wired in parallel, so every device sees the same voltage while their currents add together. Check that the power supply can deliver the combined current of all connected devices, with headroom, before connecting them.
This is a passive splitter with no regulation, fusing, or per-output protection. It does not convert voltage and does not limit current on any leg.
COMPATIBLE HARDWARE
- DC wall adapters with a 5.5 x 2.1mm plug — Standard centre positive barrel output, rated for the total load
- Bench power supplies with a barrel output — Set to the voltage all four devices require
- CCTV and IP cameras — Common 12V barrel input, up to four cameras from one supply
- 12V LED strip lights — Distribute one supply across several strip sections
- Development boards with a DC barrel jack — Power a cluster of boards from a single adapter
- Routers, switches, and modems — Where all units share the same voltage
- DC screw terminal adapters — Wire a bare supply into the splitter input
- Any group of 5.5 x 2.1mm centre positive devices — Within the supply's combined current rating
