A: This power adapter is compatible with a wide range of 5V, 9V, and 12V DC devices, including CCTV security cameras, LED light strips, desk lamps, routers, networking hardware, and many other consumer electronics that use a standard 5.5mm barrel connector. Always match the output voltage and current to your device's requirements before use.

Q: What barrel connector size does this power adapter use?

A: The connector size depends on the output variant you select. The 5V/1A, 5V/2A, 12V/0.5A, and 12V/1A models use a 5.5mm × 2.1mm barrel connector, while the 5V/3A, 12V/2A, and 9V/2A models use a 5.5mm × 2.5mm connector. The polarity is center positive (outside negative).

Q: Which plug type will I receive — US, EU, UK, or AU?

A: The plug type shipped is determined by your region: US plug for North America and Japan, EU plug for Europe, and AU plug for Australia and New Zealand. If you need a specific plug type (US, UK, EU, or AU), simply contact us before placing your order and we'll accommodate your request.

Q: Can I use this power adapter internationally while traveling?

A: Yes — the universal input voltage range of 100–240V AC means it will work with wall outlets in virtually every country worldwide. You may need a physical plug adapter (not included) if the plug type doesn't match the local socket, but the adapter itself handles the voltage conversion automatically.
