Frequently Asked Questions
Q: What devices is this DC 12V power adapter compatible with?
A: This adapter is designed for 315MHz and 433MHz wireless controllers, Wi-Fi routers, Bluetooth-compatible receivers, smart home automation modules, and any electronic device requiring a 12V DC, up to 1A power supply with a DC5.5×2.1mm barrel connector.
Q: What is the converter cable used for?
A: The included DC5.5×2.1 female converter cable allows you to connect the adapter's 12V output to devices or projects that require bare wire connections (red positive, white negative), making it ideal for custom wiring, DIY electronics, and hardwired installations.
Q: Is this adapter safe to use internationally?
A: Yes. The adapter's input range of AC 100–240V, 50/60Hz means it is compatible with electrical systems in most countries around the world. However, you may need a plug-shape adapter depending on your region's outlet type.
Q: What does centre-positive polarity mean?
A: Centre-positive polarity means the inner pin of the barrel connector carries the positive (+) voltage, and the outer sleeve is negative (−). Always verify your device requires centre-positive polarity before connecting to avoid damage.
