UNITEK Y-C495BK USB-A to DC 3.5x1.35mm Power Cable 1M 15W 5V-3A for Routers Speakers LED Lights
Replace Lost Power Cords for Your DC 3.5mm Devices
The UNITEK Y-C495BK USB-A to DC 3.5mm Power Charging Cable is designed to power devices that use a 3.5mm x 1.35mm barrel connector. Perfect for routers, LED strip lights, small speakers, webcams, baby monitors, and other electronics that run on 5V DC. Simply connect to any standard USB-A charger (5V/3A, not included) and plug into your device.
Reliable 15W (5V-3A) Power Delivery
Supports up to 15W output when used with a 5V/3A USB adapter. This is sufficient for most small electronics that require 5V input. The 20AWG bare copper conductors ensure stable current flow with minimal resistance over the 1-meter length.
Durable Construction
20AWG bare copper – thicker gauge reduces voltage drop
Nickel-plated connectors – resist corrosion, maintain good contact
4mm outer diameter jacket – flexible yet tough
Strain-relief collar – prevents cable breakage at the plug
Wide Compatibility (Check Your Device First)
This cable fits devices with a 3.5mm outer diameter and 1.35mm inner pin diameter (3.5x1.35mm). Common compatible devices include:
Some TP-Link, Netgear, and D-Link routers
LED light strips and USB-powered lamps
Portable speakers (e.g., Anker, JBL)
USB-powered fans and humidifiers
Webcams and security cameras
Note: Double-check your device's power port size. Many routers use 5.5x2.1mm or 5.5x2.5mm – this cable will NOT fit those. This is for 3.5x1.35mm only.
Plug-and-Play – No Drivers
Just plug the USB-A end into a 5V/3A charger (or any USB port, but 3A recommended for full power) and the DC barrel into your device. If your device requires a specific polarity, check that the tip matches (center positive is standard for this cable – confirm your device).
Replace lost cords, reduce desktop clutter, and power your DC devices from any USB port – UNITEK Y-C495BK.
Technical Specifications
Frequently Asked Questions
1. What devices is this cable compatible with? +
Any device that uses a DC barrel jack with 3.5mm outer diameter and 1.35mm inner pin. Common uses: routers, LED lights, USB speakers, webcams, fans, and some baby monitors. Not for laptops (laptops use larger connectors and higher voltage/wattage).
2. What is the power rating? +
15W maximum (5V, 3A). Use with a USB adapter that provides 5V and at least 3A for full power. Lower current adapters will work but may not power high-draw devices.
3. Does polarity matter? +
Yes. Most devices using this connector expect center positive (tip = positive, sleeve = ground). This cable follows that standard. If your device requires center negative, this cable will NOT work (unless you modify it – not recommended).
4. Can I use this to charge a phone or tablet? +
No. Phones use USB-C, Micro-USB, or Lightning, not a 3.5mm barrel connector.
