PD 100W USB-C to DC 5525 Power Cable – 9V 12V 15V 20V

Power Your Laptop, Router & More with a Single USB-C Cable

Say goodbye to bulky proprietary power bricks. The Shunmaii PD 100W USB-C to DC 5.5×2.5mm Power Adapter Cable lets you charge and power laptops, wireless routers, CCTV cameras, LED lights, mini fans, and dozens of other DC-powered devices — all from a standard USB-C PD charger or power bank. Choose your required output voltage (9V, 12V, 15V, or 20V) and plug in.

Key Features

• Smart E-Mark PD Chip: The built-in hardware PD recognition chip intelligently negotiates the correct voltage from your PD power source, protecting your devices from over-voltage and reverse-polarity damage.
• Up to 100W High-Power Output: At 20V/5A, this cable delivers a full 100W — enough to drive demanding laptops, stepper motors, and other high-power electronics.
• Multi-Voltage Options: Available in fixed output voltages of 9V, 12V, 15V, and 20V — simply select the version that matches your device's requirement.
• Reverse-Polarity Protection: The straight-through, direct-connection design ensures the cable physically cannot be inserted incorrectly, keeping your equipment safe at all times.
• Premium Copper Core with PVC Sheathing: A thick, high-quality copper core ensures low resistance and stable power delivery, while the durable PVC outer jacket resists wear and abrasion.
• Universal DC Tip Compatibility: The 5.5×2.5mm barrel connector is also compatible with the common 5.5×2.1mm interface, giving you even broader device support.
• Generous 120cm Length: At ~47 inches (120cm), there's plenty of cable length for comfortable desktop or workstation use.
• CE Certified: Meets European safety and electromagnetic compatibility standards for peace of mind.

Important Usage Note

The output voltage of each cable is fixed — it cannot be changed after purchase. Make sure your USB-C PD charger or power bank supports the output voltage you select (e.g., if you order the 12V cable, your charger must support 12V PD output). If your charger does not support the requested voltage, the chip will fall back to the next available lower voltage from your power source.

Frequently Asked Questions

Q: Can this USB-C to DC adapter cable work with any USB-C charger?

A: No — this cable requires a USB-C charger that supports Power Delivery (PD) at the voltage you need. It does not work with Quick Charge (QC) chargers. For example, if you purchase the 12V version, your PD charger must include a 12V PD output profile. Always check your charger's PD voltage output list before ordering.

Q: Does this cable support 100W charging for all voltage options?

A: Maximum power depends on the voltage version selected. The 20V version supports up to 100W (20V × 5A). Lower voltage versions (9V, 12V, 15V) will deliver proportionally less wattage based on the current their PD source can supply.

Q: Is the DC barrel connector compatible with my 5.5×2.1mm laptop or router port?

A: Yes! The 5.5×2.5mm tuning-fork-style barrel plug has some flexibility and is compatible with the common 5.5×2.1mm DC jack, making it suitable for a wide range of routers, laptops, and accessories.

Q: Can I use this cable to charge my smartphone via the DC barrel connector?

A: No. This cable is designed to convert USB-C PD power to a DC barrel output. It should be used to power devices with a DC 5.5×2.5mm input port (such as routers and laptops), not as a standard smartphone charging cable.
