Reliable DC Power Extension

This Tonton two-pack supplies two 3.3FT DC power extension cables with 5.5 mm x 2.1 mm 5521 male-to-female connectors. They deliver 12V DC power to CCTV security IP cameras, surveillance DVR units, LED strips and monitors. The white PVC jacket blends cleanly into indoor or outdoor installations.

Simple Inline Connection

Each cord plugs inline between an existing 12V DC source and the device, adding 1M of reach without tools or splicing. The 5521 barrel connectors snap securely into place, supporting up to 3A current draw across a 0-36V range. High-grade copper cores and IP66-rated insulation maintain stable power in exposed locations.

Replaces Short Factory Leads

These extensions replace the short fixed tails that ship with many cameras and LED kits, letting you route power to optimal mounting points. The jump is worth it when the stock cable cannot reach the nearest outlet or when you need a weatherproof run between enclosures. Buyers needing longer single runs or different barrel sizes should check other lengths in the range.

Questions about this item

Will the 12 V 3 A rating hold up on a 3.3 ft run?

The cable is rated for DC 12 V at a maximum of 3 A, so the 3.3 ft length will carry that load without exceeding its specification.

Does the IP66 jacket add noticeable heat during continuous outdoor use?

The PVC-insulated, high-grade copper core is rated IP66 for weatherproofing and is designed to run continuously without generating excess heat under the stated 12 V 3 A load.

My camera uses a 5.5 × 2.1 mm barrel plug — will the 5521 connectors fit directly?

Yes, the male and female 5.5 mm × 2.1 mm 5521 connectors match that barrel size exactly, so no adapter is needed.
