Frequently Asked Questions

Q: Will this 12V power supply adapter work in both the US and Europe?

A: Yes! This universal switching power supply accepts AC input from 100V to 245V at 50–60Hz, making it compatible with electrical outlets in the United States, Europe, and most countries worldwide. Simply choose the appropriate plug type (EU or US) when ordering.

Q: What current rating (1A, 2A, or 3A) should I choose for my LED strip lights?

A: The current rating depends on the total wattage of your LED strip. Divide the total wattage of your LED strip by 12V to get the required amperage. For example, a 20W LED strip requires at least a 2A adapter (20W ÷ 12V = 1.67A). Always choose a rating slightly above your requirement for safe, stable operation.

Q: Can I use this power adapter outdoors?

A: No. This power supply adapter is designed for indoor use only and is not waterproof. Please ensure it is kept away from moisture, rain, and water to avoid damage or electrical hazards.

Q: What is the DC connector size for this power supply?

A: This adapter uses a standard 5.5mm × 2.5mm DC barrel connector, which is compatible with the majority of 12V LED strips, routers, cameras, and other DC-powered devices. Please verify your device's connector size before purchasing.
