🧰 What This Cable Does

This cable lets you power DC devices (with 5.5×2.1mm or 5.5×2.5mm plug) directly from your car’s cigarette lighter socket.

Typical uses:

• Dash cams & car cameras
• WiFi routers / ONT devices
• LED strips / lights
• Mini fans, pumps, small electronics

It basically converts car 12V output → DC barrel plug input.

⚙️ Key Specifications (Important)

• Input: Car cigarette lighter (12V–24V)
• Output plug: DC5521 / DC5525 (5.5mm outer)
• Max current: ~5A (important limit)
• Length: ~1.2 meters
• LED indicator: Shows power status
• Fuse protection: Prevents short circuit damage

✅ Pros

• ✔️ Plug & play (no wiring needed)
• ✔️ LED helps troubleshoot power
• ✔️ Safe (built-in fuse)
• ✔️ Works with most 12V devices

⚠️ Things to Check Before Buying

1. Connector size
   • DC5521 = 5.5×2.1mm
   • DC5525 = 5.5×2.5mm
     👉 Make sure your device matches
2. Power requirement
   • Max ~5A → about 60W (12V × 5A)
   • Not suitable for heavy devices (heaters, big compressors)
3. Polarity
   • Usually center positive (standard)

💡 Real-World Tip

Many people use this cable for WiFi routers during load shedding or powering electronics from batteries/cars.
But don’t overload it—thin DC cables can heat up if pushed beyond rating.

👍 Should You Buy It?

• ✔️ Yes — for small 12V electronics
• ✔️ Yes — for backup power setups
• ❌ No — for high-power devices (>60W)
