🔌🔀 DC Barrel Power Splitter Cable

DC barrel splitter cables allow a single DC power source to be shared across multiple devices. With standardized 5.5mm outer diameter and 2.1mm inner pin, these splitters are ideal for CCTV, LED lighting, embedded systems, and modular AV setups. Available in various gender configurations and output counts to match your gear and layout.
 
🔧 Splitter Variants (5.5mm / 2.1mm • 5.5mm / 2.1mm)
1️⃣ 1x2 Splitter
Female-to-Male: 1 female input → 2 male outputs
Use Case: Power two devices from one adapter
Example: 12V PSU → two cameras or LED strips
2️⃣ 1x3 Splitter
Female-to-Female: 1 female input → 3 female outputs
Use Case: Split male plug into three female jacks
Example: Male-ended PSU → three extension cables
3️⃣ 1x4 Splitter
Female-to-Male: 1 female input → 4 male outputs
Use Case: Power up to four devices simultaneously
Example: CCTV quad setup or multi-zone lighting
4️⃣ 1x8 Splitter
Female-to-Male: 1 female input → 8 male outputs
Use Case: Large-scale power distribution
Example: Full rack of surveillance cameras or LED arrays
 
🖥️ Compatible Devices
📷 CCTV cameras and DVRs
💡 LED strips, signage, and light panels
📡 Routers, modems, and embedded boards
🔊 Audio amplifiers and small speaker systems
🧰 Power hubs, splitters, and control boxes

✅ Common Uses
🔄 Power multiple devices from one adapter
🧩 Split power to multiple zones or modules
🛠️ Route power through racks or enclosures
🔧 Extend reach with gender-matched cables
🧪 Test voltage delivery across multiple endpoints
 
🧠 Signal Format Notes
Voltage Range: Typically 5V–48V DC
Current Capacity: Shared across outputs—check total draw
Polarity: Usually center-positive—always verify
Connector Type: Cylindrical barrel with inner pin and outer sleeve
❗ No voltage regulation—splits raw power only
 
⚠️ Things to Watch Out For
🔌 Total current draw must not exceed power supply rating
📏 Longer splitter chains may cause voltage drop
🧯 Confirm polarity and connector size—2.1mm vs 2.5mm inner pin
🔄 Female-to-female splitters require male plug input
🧪 Use multimeter to test voltage before connecting sensitive gear
 
🛠️ Quick Tips for Beginners
🔍 Measure barrel size—5.5mm outer / 2.1mm inner is standard
🧭 Use female-to-male for device-side splitting; female-to-female for cable-side
🧰 Keep labeled splitters in your toolkit for quick deployment
🧪 Test with one device first before powering multiples
🧼 Coil gently—avoid stress near splitter junctions
