SKU CH-WC54-0SWMG

A kit of 28 DC plug tips with a 5.5x2.1mm female input for powering laptops, routers, cameras and LED strips

  • 28 interchangeable tips cover most common DC barrel sizes
  • Standard 5.5 x 2.1 mm female input fits universal multi‑voltage adapters
  • Gold‑plated oxygen‑free copper pins give stable conductivity and resist oxidation
  • Hard insulated plastic shells withstand compression and drops for lasting fit
  • Compact portable case keeps all tips organised for laptops routers CCTV LED strips and small electronics

Universal DC Tip Kit

This 28-piece kit supplies a comprehensive selection of male DC barrel connectors that share a single 5.5mm by 2.1mm female input. It is intended for technicians, installers and hobbyists who regularly service laptops, routers, CCTV cameras, LED strips and similar small electronics.

Critical Interface Match

Every tip in the set terminates in the same 5.5mm x 2.1mm female jack, so the kit only works with power supplies that already provide that exact barrel plug. If your adapter uses a different outer or inner diameter, none of the included tips will connect.

Sustained Connection Reliability

Gold-plated oxygen-free copper pins maintain low contact resistance over long periods, reducing the risk of voltage drop, intermittent power or device restarts during continuous operation. The rigid insulated shells resist deformation so the fit stays secure even after repeated mating cycles.

Questions about this item

How many different plug sizes are included in the 28-piece kit?

The kit contains 28 distinct DC male connector tips, each with a different barrel diameter and pin combination to match the most common jack sizes found on laptops, routers, cameras and LED strips.

What does the 5.5 x 2.1 mm female common input mean for compatibility?

Every tip in the set shares a standard 5.5 mm outer diameter and 2.1 mm inner pin female socket, so they all snap onto the same universal power cord or multi-voltage adapter without needing separate cables.

What physical space is needed to store or carry the 28 tips?

The tips are housed in a compact, lightweight plastic case with individual compartments, making the whole kit small enough to fit in a tool bag, laptop sleeve or glove compartment.
