USB to 12V DC Boost Converter Cable | Power Bank to Router

Power Your 12V Devices from Any USB Power Source

The USB to 12V DC Boost Converter Cable is a compact, intelligent power solution that upgrades a standard 5V USB output to a stable 12V DC supply. Whether you're powering a Wi-Fi router during a power outage, running a portable fan, or keeping a small speaker going on the go, this cable lets your everyday power bank or USB charger do the job — no bulky adapters required. Made in Mainland China.

Key Features

• Stable 12V Output: High-precision boost circuit converts 5V USB input to a steady 12V DC output with no voltage fluctuation, keeping your 12V electronics running consistently and safely.
• Durable PVC-Insulated Tinned Copper Core: Flexible, high-quality construction resists bending, fraying, and oxidation over repeated long-term use — extending cable lifespan and saving you replacement costs.
• Universal Compatibility: Standard USB-A male plug and DC barrel connector work with virtually all USB power sources — power banks, laptop USB ports, wall USB chargers, and car USB ports — to power most common 12V small electronics.
• Multiple Safety Protections: Built-in overcurrent, overvoltage, and short-circuit protection automatically cuts power when abnormal electrical conditions are detected, protecting both the power source and connected device.
• Tangle-Resistant & Portable: Anti-kink spring strain relief at both connector ends prevents breakage at the joint and keeps the cable tangle-free during storage or travel — ideal for outdoor, camping, and office use.

Frequently Asked Questions

Q: What USB power sources are compatible with this 5V to 12V boost converter cable?

A: This USB to 12V DC boost converter cable is designed to work with any standard 5V USB power source, including power banks, laptop USB ports, wall USB chargers, and car USB adapters. As long as your USB source outputs 5V (standard for all USB-A ports), the cable will boost it to a stable 12V DC output.

Q: What devices can I power with this USB to 12V converter cable?

A: This cable is compatible with most 12V small electronics, including Wi-Fi routers, portable fans, LED light strips, surveillance cameras, and small speakers. It is ideal for home, office, travel, and outdoor camping use where a 12V power supply is needed but a mains outlet is not available.

Q: Is it safe to use this boost converter cable with my power bank?

A: Yes. The cable features built-in overcurrent, overvoltage, and short-circuit protection, which automatically cuts the power supply if abnormal electrical conditions are detected. This safeguards both your power bank and your connected 12V device for worry-free use.

Q: Does this cable support USB Type-C input?

A: This cable uses a USB-A male plug as the input connector. If your power source only has a USB Type-C port, you would need a USB-C to USB-A adapter to use it. The output end features a standard DC barrel connector suitable for most 12V small devices.
