Quick Overview
The DIYables 1 to 2 DC Power Splitter takes a single DC supply and feeds two devices from it. The input is a 5.5 x 2.1mm female barrel jack that plugs onto a standard DC adapter, and the cable divides at a moulded junction into two legs, each ending in a 5.5 x 2.1mm male plug. All three connectors are wired centre positive, matching the convention used by ordinary wall adapters.
Because the two outputs are wired in parallel, both devices receive the same voltage as the source, and the current they draw adds together. That makes the supply rating the thing to plan around: the adapter must be able to deliver the total of both loads, not just the larger one. Used within that limit, the splitter removes the need for a second wall adapter and a second outlet, which is the usual reason it appears in CCTV installs and LED strip runs.
Ideal for powering two cameras from one supply, splitting 12V to two LED strip sections, feeding a pair of development boards or routers from a bench adapter, and tidying any setup where two nearby devices share the same voltage. This listing includes 2 cables.
Key Features
- One Input, Two Outputs — A single female barrel jack feeds two 5.5 x 2.1mm male plugs from one supply
- 5.5 x 2.1mm Throughout — Input and both outputs use the same widely adopted barrel size, matching most DC adapters
- Centre Positive Wiring — All three connectors follow the standard polarity convention used by wall adapters
- Parallel Outputs — Both legs deliver the full source voltage, so identical devices can share one adapter
- Moulded Y Junction — The split is enclosed in a moulded body that supports the cable and resists pulling apart
- Flexible Cable — Slim, flexible legs route easily behind cameras, along strip runs, or inside an enclosure
- Removes a Second Adapter — One supply and one outlet serve two devices instead of two of each
- No Wiring or Soldering — Plug-and-play connectors with nothing to strip, splice, or terminate
- Works With DC Adapters — Pairs with barrel-jack wall adapters, bench supplies, and screw terminal adapters
- 2 Pack — Two splitter cables for separate installs or a spare
SPECIFICATION
| Specification | Value |
|---|---|
| Product Type | DC Power Splitter Cable, 1 to 2 |
| Input Connector | DC barrel jack, 5.5 x 2.1mm female |

※ NOTE THAT:
The two outputs are wired in parallel, so both devices see the same voltage while their currents add together. Check that the power supply can deliver the combined current of both devices before connecting them.
This is a passive splitter with no regulation or fusing. It does not convert voltage and does not protect against overload.
COMPATIBLE HARDWARE
- DC wall adapters with a 5.5 x 2.1mm plug — Standard centre positive barrel output
- Bench power supplies with a barrel output — Set to the voltage both devices require
- CCTV and IP cameras — Common 12V barrel input, two cameras from one supply
- 12V LED strip lights — Split one supply across two strip sections
- Development boards with a DC barrel jack — Power two boards from a single adapter
- Routers, switches, and modems — Where both units share the same voltage
- DC screw terminal adapters — Wire a bare supply into the splitter input
- Any pair of 5.5 x 2.1mm centre positive devices — Within the supply's combined current rating
