DC extension 2.50 m (male > socket); 5.5/2.1 mm; for low voltage applications; connector for power supply/LED strip/camera/CTV.

Does the job

Took some time but finally discovered that centre pole diameter of the male connector was too small a diameter to fit into the corresponding female connector. Being reasonable practical I attempted to open up the diameter of said connector. Due to the flimsiness of the product I destroyed to centre pole. Not pleased.

Excellent
