Great for office equipment

Purchased for a set-top box in our conference room. Delivery was fast, and the unit is compact enough to hide behind the TV. No electrical hum or interference with our audio system.

Good value for security cameras

Bought three of these to power my outdoor CCTV cameras. They work well and the cable length is sufficient. One star off because the plug feels slightly loose on one of my older camera models, but it still maintains connection.

Works but connector size check needed

The adapter works fine electrically, but make sure you check your device's port size. I had to use an adapter tip because my old speaker system uses a slightly smaller barrel jack. Once sorted, it works great.

Reliable and quiet

Using this to power an LED light strip behind my monitor. It provides consistent brightness with no flickering. Very happy with the build quality and the fact that it doesn't get hot during extended use.

Perfect replacement for my lost router adapter

I lost the original power brick for my TP-Link router and this UGREEN adapter worked flawlessly. The fit is snug, and the router boots up instantly without any noise or heating issues.

Solid build quality

UGREEN never disappoints. The casing feels durable, and the strain relief on the cable is a nice touch. It has been running my external hard drive enclosure for two weeks straight without any drops in power.

5 FAQ

Q: Is the polarity center-positive or center-negative?

A: This adapter features a standard center-positive polarity configuration, which is compatible with most routers and modems.

Q: Will this work with a device that requires 12V 1A?

A: Yes, this adapter provides up to 2A. Your device will only draw the 1A it needs, so it is perfectly safe to use.

Q: Can I use this outdoors for a security camera?

A: The adapter itself is not weatherproof. It should be used indoors or placed in a waterproof enclosure if used outside to protect it from rain and moisture.

Q: What happens if there is a power surge?

A: The adapter includes built-in protection against over-voltage and short circuits, which helps safeguard your connected devices from sudden power spikes.

Q: Does this come with interchangeable tips for different devices?

A: No, this specific model comes with a fixed DC round plug (5.5mm x 2.5mm). We do sell separate tip adapter kits if your device requires a different size.
