4pcs 12V DC Power Extension Cable 33ft 10m 2.1mm x 5.5mm Male-Female Connectors

What this kit provides

This kit contains four 33ft extension cables and four barrel jack adapters, two male and two female, all sized at 2.1mm by 5.5mm. It is intended for anyone who needs to run low-voltage DC power to security cameras, LED strips, routers or similar devices over longer distances. The pure copper conductors keep voltage drop low across the 10 metre length. Buyers who need a different barrel size or an AC-rated cord cannot use this product.

Check your existing gear

Verify that every device you plan to connect uses a 2.1mm inner by 5.5mm outer DC barrel jack and operates on 12 V DC. The included adapters only fit that exact size; other diameters will not mate. If your equipment uses 16 to 24 AWG bare wires, the screw-terminal adapters can terminate them. Ensure your power supply can deliver the total current for all connected loads before cascading cables.

Build quality and daily use

Each cable uses a pure copper core wrapped in a tough, flexible black jacket that resists repeated bending indoors or outdoors. The male-to-female barrels lock together securely, and two cables can be joined to reach 66 ft without tools. Four zip ties and ten adhesive wire clips are supplied for neat routing along walls or ceilings. The connectors are straight blade plugs, so allow clearance behind the device for the straight exit.
