Needed to power my security camera which was too far away from the outlet. Manufacturer recommended wire to be no more than 15 ft to ensure reliable operation. The 10 feet cable extension plus the 6 feet power adapter that came with the camera fit the requirement. Camera is working great.

I recently purchased the SIOCEN 2-Pack 10FT DC Power Extension Cable (5.5mm x 2.1mm) from Amazon, and I am extremely pleased with their performance! While these cables are perfect for security cameras and LED strip lights, I found them to be an exceptional solution for improving the tracking of my Meta Oculus 2 VR headset using an IR light mounted on my ceiling.The 10FT length of these cables provides ample reach to connect my ceiling-mounted IR light without any issues. The 5.5mm x 2.1mm connectors are a universal size, making them compatible not only with my IR light but also with other devices such as CCTV IP cameras, routers, and LED strips. The cables work seamlessly with a range of voltages, including 5V, 9V, 12V, and 24V devices.The build quality of the SIOCEN extension cords is exceptional. They are both flexible and durable, ensuring a long-lasting product that can withstand frequent use. The male-to-female plug design guarantees a secure connection between my devices and power adapters, so there's no need to worry about accidental disconnections or power interruptions.These extension cords have not only improved the tracking of my Meta Oculus 2 VR headset, but they have also helped me maintain a clean and clutter-free setup.

These are so useful because when you buy your cameras on almost any site the power cord is always way too short. I will be using this product for many reasons other than its length but also because its very thick and high quality..

There isn't much more to say in the review. This two-pack of cables worked great to extend some really short cables attached to some lit movie poster boxes. This proved helpful as I was able to more easily hide the wires going to the boxes and neither the adapter nor the poster box itself seemed to work any harder nor were warmer than usual.Overall, great product if you have a need for a longer adapter cord! Just make sure you're ordering the correct adapter barrel size. Here's an easy guide I followed to figure out which size I needed:The most common barrel outer diameter is 5.5 mm with two very common inner diameter (ID) measurements of 2.1 mm and 2.5 mm. These are very close and near impossible to take an accurate measurement with a ruler. So, if there’s not a caliper in sight, a toothpick, pen, or test lead can be used.Toothpicks are commonly manufactured at a diameter of 2.1 mm to 2.2 mm. If it fits snug when inserted into the connector, then the ID is probably 2.1 mm, whereas if it falls out, then it’s 2.5 mm.The widest point of a ballpoint pen should be between 2.25 mm and 2.35 mm. If the pen fits all the way to the widest point, the ID is 2.5 mm. If it only fits part way, then it is likely 2.1 mm.

I installed a 6 cameras security system with cameras that require power from an outlet. Optimal placement of most of the cameras put them well beyond the reach of power. These extension cables added the necessary length to plug them in. They deliver continuous power, and I haven't had any issues with flickering or power loss.

I needed this for a DAC. It’s great that two cables are included though I only needed one. Absolutely no problems and will buy again if I need more in the future
