USB to 12V DC Boost Cable 4.0x1.7mm 90° | 100cm Power Adapter

Power Your 12V Devices from Any USB Port

This compact 90-degree USB 5V to 12V DC boost power cable lets you run 12V devices — such as Bluetooth speakers, wireless routers, LED strip lights, fans, and more — directly from a USB power bank, wall adapter, or car charger. No bulky dedicated power adapter needed!

With a USB-A male input and a 4.0x1.7mm DC barrel plug output, this cable intelligently steps up standard 5V USB power to 12V DC (max 6W / 0.5A), giving your low-power 12V gadgets the juice they need from virtually any USB source.

Key Features

• 90° Right-Angle Design: Space-saving angled connector reduces strain on ports in tight spaces
• USB 5V to 12V Step-Up: Input DC 5V 2A → Output DC 12V 0.5A (6W max)
• Universal DC Connector: 4.0mm OD / 1.7mm ID barrel plug (positive center pin, negative outer sleeve) — please verify compatibility with your device's power jack before ordering
• Generous 100cm Cable Length: Approx. 1 meter gives you flexible reach
• Broad Compatibility: Works with Bluetooth speakers, wireless routers, LED strip lights, small fans, LED lamps, and other 12V low-power devices (no internal battery required)
• Multiple USB Power Sources: Compatible with wall USB adapters, power banks, and car chargers — wall USB adapter recommended for best performance
• Available in Black & White: Choose the color that suits your setup

Important Notes

• Maximum output is 6W (12V × 0.5A). Only suitable for devices that operate within this power range.
• Some power banks with auto-shutoff features (triggered at low current draw, e.g. ~90mA) may cut power automatically — a wall USB adapter is strongly recommended.
• Please confirm your device uses a 4.0mm (OD) × 1.7mm (ID) power jack before purchasing.
• Cable adapter only — no USB adapter/charger included.

Frequently Asked Questions

Q: What devices is this USB to 12V DC cable compatible with?

A: This USB 5V to 12V DC power cable is compatible with any device that uses a 4.0mm OD × 1.7mm ID DC barrel connector and requires 12V at 0.5A or less (up to 6W max). Common uses include Bluetooth speakers, wireless routers, LED strip lights, small fans, and LED lamps. Always check your device's power jack size and wattage requirements before use.

Q: Can I use this cable with a power bank?

A: Yes, in most cases. However, some power banks feature an automatic shutoff that activates when the current draw is very low (around 90mA). If your device draws minimal current and your power bank shuts off, switch to a wall USB adapter for uninterrupted power delivery.

Q: What does the 90-degree connector mean, and why does it matter?

A: The 90-degree (right-angle) connector means the USB plug exits at a perpendicular angle rather than straight out. This is ideal for tight spaces — such as behind furniture or inside media centers — where a straight plug might be too bulky or cause bending stress on the cable.

Q: Is this cable safe to use with my router or smart speaker?

A: This cable is designed for low-power 12V devices (max 6W output). As long as your device operates within these power limits and uses the correct DC barrel connector size (4.0×1.7mm, center positive), it is suitable for use. Always verify your device's power requirements on its label or manual before connecting.
