Full Product Description

Reliable 5V Power for Your Essential Electronics

Using an unstable or underpowered adapter can cause your electronics to malfunction, reboot randomly, or fail prematurely. This 5V 3A Switching Power Adapter is engineered to provide a clean, regulated 5-volt direct current (DC) up to 3000mA (15 Watts). Its convenient "wall-wart" design integrates the UK 3-pin plug directly into the power brick, eliminating the need for a separate AC power cord and keeping your wall outlets neat and organized.

Universal 5.5x2.1mm Compatibility

The connector size is the most critical part of choosing a replacement charger. This adapter comes equipped with the highly universal 5.5mm (outer diameter) x 2.1mm (inner diameter) barrel plug with a center-positive polarity. This is the exact specification required for a vast majority of 5V home appliances, including network switches, HDMI matrixes, TV boxes, and custom Arduino/Raspberry Pi projects.

Level VI Energy Efficiency & Global-Ready

Built for daily household and commercial use, this adapter features a universal AC 100-240V (50/60Hz) input, allowing it to safely handle voltage fluctuations. It boasts the highest Level VI Efficiency rating, ensuring minimal power is wasted as heat during operation. The durable black casing provides solid protection against everyday wear and tear, ensuring a long operational lifespan.

💡 Pro Tip from Our Technicians

"A very common question we get is: 'Can I use a 3A adapter for a device that only needs 1A or 2A?' Yes, absolutely! An electronic device will only draw the amperage it needs. Using a 3A adapter for a 1A device means the power supply won't have to work as hard, resulting in less heat and a much longer lifespan! However, never mix up voltages. Plugging a 5V adapter into a 12V device won't work, and plugging a 12V adapter into a 5V device will destroy it. If you are unsure about your device's voltage requirements or plug size, bring it to our Sham Shui Po store! Our team at Sun Cheong Computer Co. Ltd. will test your device and find the exact power adapter you need on the spot."

FAQ Section

Can I use this 5V 3A adapter for a device that requires 5V 1A or 2A?Yes, absolutely. An electronic device only draws the current (Amps) it needs. Since this adapter can provide up to 3A, it will easily and safely power your 1A or 2A device without causing any damage, and the adapter will run cooler as a result.
How do I know if the 5.5x2.1mm plug will fit my device?The 5.5x2.1mm plug is the industry standard for small DC electronics. You can measure the port on your device—the hole should be roughly 5.5mm wide across. If you are in Hong Kong, you can bring your device to our Sham Shui Po store to test the fit before buying.
Does this adapter need a separate power cord to plug into the wall?No. This is a "wall-wart" style adapter, meaning the UK 3-pin plug is built directly into the power brick. You plug the entire unit directly into your wall socket or power strip, saving space and reducing cable clutter.
