Frequently Asked Questions

Q: What devices is the DC 5V 2A EU Power Supply Adapter compatible with?

A: This adapter is compatible with any device that requires a DC 5V power input via a 5.5mm x 2.1mm barrel connector, including level gauges, LED strips, microcontroller development boards, CCTV cameras, routers, and other low-voltage electronics rated at 5V up to 2A (2000mA).

Q: Is this power adapter safe to use in European countries?

A: Yes. This adapter features a standard EU plug and accepts a universal AC input range of 100–240V at 50/60Hz, making it fully compatible with European mains power and suitable for use in most countries worldwide.

Q: What does the centre-positive (inside positive) polarity mean?

A: Centre-positive means the inner pin of the 5.5mm x 2.1mm barrel connector carries the positive (+) charge, while the outer sleeve is negative (–). This is the most common polarity for consumer electronics — always verify your device's required polarity before connecting.

Q: Does the adapter stop charging automatically?

A: Yes. The adapter includes an auto-stop function. The red LED illuminates during operation and the green LED lights up when the connected device reaches full charge, at which point charging stops automatically to protect your device.
