Question 1

Is this adapter safe to leave plugged in 24/7 for my CCTV camera or LED strip?**

Accepted Answer

Yes, this adapter is designed for continuous operation, making it suitable for security cameras that run all day. However, it’s a light-duty unit, so it’s best used with a single camera or a short strip (under 2 meters). Like most compact power supplies, it may run warm to the touch during extended use—that’s normal. For heavy loads or outdoor installations, we recommend upgrading to a higher-spec or waterproof adapter.

Question 2

Will the DC plug fit my device? What about the polarity?**

Accepted Answer

This adapter uses the most common DC barrel jack size: **5.5mm outer diameter x 2.1mm inner pin**. It’s compatible with the vast majority of CCTV cameras and LED controllers. The polarity is **center positive**, which is standard for 12V devices. If your device has a different pin size (like 2.5mm), you’ll need a converter plug or a different adapter. A quick check of your device’s manual or the label next to the power port will confirm.

Question 3

Can I use this to power my LED strip lights? How long of a strip will it handle?**

Accepted Answer

Yes, it will work with most 12V LED strips. Since it delivers 1A (12W), it’s ideal for **up to 2 meters** of standard 5050 LED strip (which typically draws 4-5W per meter). If you try to power a longer strip, you’ll notice dimming at the end of the line or the adapter overheating. For strips longer than 2 meters, you’ll need a higher-amperage adapter (e.g., 3A or 5A).

Question 4

The cable seems short. Can I extend it, and does this affect the UK plug?**

Accepted Answer

The DC cable is roughly 1 meter long, which is on the shorter side for mounting cameras on high ceilings. You can easily extend it using a **DC extension cable** or a barrel jack coupler—just make sure the wire gauge is thick enough (18 AWG or lower) to avoid voltage drop over long distances. The UK plug itself is a standard 3-pin BS 1363 type, so it fits normal UK wall sockets. If you have shuttered sockets, the plug works fine—there are no alignment issues.

Question 5

What if it stops working after a few weeks? Is there a warranty or refund policy?**

Accepted Answer

We stand behind this product with a **30-day money-back guarantee and a 12-month replacement warranty** against manufacturing defects. If you receive a dead unit or it fails during normal use, contact our support team with your order number, and we’ll send a replacement or process a refund quickly. That said, protect the adapter from moisture and ensure it’s not overloaded—most failures are caused by pairing it with devices drawing more than 1A.
