Description
The USB to DC 5V to 12V Step-Up Booster Converter Cable is a clever power adapter cable equipped with a built-in voltage-boosting circuit. It takes standard 5V DC power from a USB port—such as a power bank, wall charger, or laptop—and steps it up to 12V DC, allowing you to run 12V electronic devices during power outages or away from standard wall outlets.
Featuring a standard 5.5mm outer diameter / 2.1mm inner diameter DC barrel jack with center-positive polarity, this 1-meter cable is ideal for powering Wi-Fi routers, optical network terminals (light cats), network switches, LED lights, and mini speakers directly from a portable power bank.
Note: Always verify that your target device operates at 12V and matches the center-positive polarity (Outer Negative, Inner Positive) before connecting.
Key Features
- 5V to 12V Voltage Step-Up: Integrated boost converter circuit transforms standard 5V USB input into a stable 12V DC output.
- Standard DC Barrel Tip: Outfitted with a widely used 5.5mm x 2.1mm DC jack connector.
- Pure Copper Core: High-conductivity internal copper wiring ensures efficient power delivery with minimal voltage drop.
- Convenient Length: 1-meter cable length offers comfortable reach between your power source and equipment.
Benefits
- Uninterrupted Internet Access: Enables you to power your Wi-Fi router or modem using a standard USB power bank during grid power failures.
- Portable Power Solution: Eliminates the need for bulky AC/DC adapters when running small 12V electronics on the go.
- Plug-and-Play Simplicity: Simple connection requires no technical configuration or external drivers.
Applications
- Emergency Wi-Fi Backup: Connecting 12V Wi-Fi routers and broadband modems to power banks during blackouts.
- Portable Electronics: Powering 12V desk lamps, mini cooling fans, Bluetooth speakers, or car air purifiers from USB power sources.
- Low-Power Networking: Running small network switches and optical network terminals remotely.
Package Includes
- 1 x USB 5V to DC 12V Step-Up Booster Converter Cable (5.5 x 2.1mm, 1 Meter)
