AC/DC Adapters: FAQ

How do I ensure the adapter fits my device?

Check the output voltage (V) and current (A) on your old label; voltage must match exactly, while amps must be equal or higher. Also, verify the connector tip size (outer/inner diameter) to ensure a snug physical connection.

How can I tell if a power adapter is safe?

Look for safety certifications like CE, FCC, or RoHS listed in the product specifications. High-quality adapters often feature over-voltage, over-current, and short-circuit protection to prevent damaging your electronics.

What is the advantage of Switching vs. Linear adapters?

Switching power supplies are lighter, smaller, and more energy-efficient compared to older linear transformers. They generate less heat and are the modern standard for sensitive electronics like laptops and LED strips.

Will the plug fit my country's wall outlet?

Most AliExpress sellers offer US, EU, UK, and AU plug options directly on the product page. Always select the specific plug type for your region during checkout, or buy a model with interchangeable heads for travel.

Recommendations for buyers

✓
Voltage Matching is Critical
Never use an adapter with a higher voltage than your device requires, as this can fry internal circuits. While Amperage (Amps) can be higher than required, Voltage must be exact.
✓
Check Connector Polarity
Verify if your device is Center Positive or Center Negative before buying. Most modern consumer electronics are Center Positive, but reversing this polarity will likely damage the unit.
✓
Efficiency Standards
Look for Level VI efficiency markings in the description. These adapters meet modern energy-saving standards, producing less waste heat and reducing electricity usage.
