USB Power Adapter Bare Wire Leads – 220V to 5V Buck Converter
USB Power Adapter Bare Wire Leads – 220V to 5V Buck Converter
Wired USB Power Adapter with Bare Wire Leads – Compact 220V to 5V Buck Converter
This wired USB power adapter is a compact, reliable voltage step-down module designed for clean, permanent low-voltage installations. Built from durable ABS and metal with a white finish, it converts standard 220V household power down to a stable 5V DC output — perfect for hardwiring small electronics without bulky chargers or extra adapters.
Key Features
- 220V to 5V Step-Down Conversion: Efficiently reduces standard mains voltage to a consistent 5V DC output for powering USB-compatible devices.
- Bare Wire Leads for Direct Hardwiring: One end features exposed bare wire leads for direct connection into junction boxes, custom wiring harnesses, or permanent installations — no plug required on the input side.
- USB Female Port Output: The output end provides a standard USB-A female port for plug-and-play device connection, keeping installations neat and flexible.
- Stable Voltage Regulation: Built-in buck converter circuitry maintains a steady 5V output even with minor fluctuations in the input line, supporting consistent performance for continuously running electronics.
- Compact 30 cm Cable: The 30 cm (approx. 11.8 in) cable length is ideal for tight spaces, false ceilings, wall cavities, and discreet installations where excess cable would be impractical.
- Low Heat Operation: High-efficiency design minimises heat generation during extended operation, making it well-suited for enclosed or semi-enclosed mounting locations.
- Broad Input Voltage Range: Accepts USB input in the 5–20V DC range, offering further versatility for varied power source configurations.
- ABS + Metal Construction: Robust housing provides lasting durability for long-term, permanent setups.

Frequently Asked Questions
Q: What does the bare wire lead end connect to on this USB power adapter?
A: The bare wire leads on the input end are designed for direct hardwiring into a 220V mains power source, such as a junction box, wiring harness, or terminal block. This makes it ideal for permanent, concealed installations where a standard plug would be impractical. Always ensure connections are made by a qualified electrician and in compliance with local electrical codes.
Q: Can I use this USB power adapter to power a security camera continuously?
A: Yes. The buck converter's stable voltage regulation and low-heat, high-efficiency design make it well-suited for devices that run continuously, such as hardwired security cameras, Wi-Fi monitoring devices, and similar 5V-compatible electronics. The consistent 5V output helps maintain steady, reliable performance over extended periods.
Q: Is the 30 cm cable length sufficient for most installation scenarios?
A: The 30 cm cable is specifically designed for compact, discreet installations — such as inside wall cavities, ceiling spaces, or junction boxes — where a shorter cable keeps wiring tidy and avoids excess slack. For longer runs, extend with appropriate gauge wire on the input side before connecting to the module.
Q: What devices are compatible with this 220V to 5V USB converter?
A: Any device that charges or operates via a standard USB-A connection at 5V DC is compatible. Common examples include small wireless cameras, Wi-Fi routers, smart sensors, LED strip controllers, and other low-power electronics that typically use a USB power supply.
