  • Powers many 5 V devices from one cable

Universal DC Power Cable with Nine Tips

The PK-549A cable converts any standard USB port into a 5 V DC power source. A 5.5 × 2.1 mm barrel jack on the main lead accepts nine interchangeable tips covering sizes from 2.5 mm up to 6.4 mm. Pure copper conductors and a durable, environmentally friendly jacket provide stable current delivery for compatible devices.

Suits owners of 5 V gadgets needing one

Users with routers, LED lights, mini fans, speakers, moon lamps or similar 5 V hardware can replace multiple proprietary adapters with this single kit. Buyers whose equipment requires a voltage other than 5 V or a tip diameter not listed among the nine supplied sizes must look for a different solution.

Nine swappable DC tips from 2.5 mm to 6.4 mm

The assortment includes 2.5 mm pin, 3.5 × 1.35 mm, 4.0 × 1.7 mm, 4.8 × 1.7 mm, 5.5 × 1.7 mm, 5.5 × 2.1 mm, 5.5 × 2.5 mm, 6.3 × 3.0 mm and 6.4 × 4.4 mm connectors. Matching the device’s exact barrel dimensions is the single specification that decides whether this cable will work.

Questions about this item

Which of the nine interchangeable DC connectors should I pick for my device?

Match the connector to your device's power jack: the set includes 6.4×4.4 mm, 6.3×3.0 mm, 5.5×2.5 mm, 5.5×2.1 mm, 5.5×1.7 mm, 4.8×1.7 mm, 4.0×1.7 mm, 3.5×1.35 mm and a 2.5 mm pin adapter.

What does the 5 V DC output actually deliver when I plug this into a laptop or power bank?

The cable passes whatever current the host USB port supplies — typically 0.5 A to 2 A — so the connected device must operate within that limit at 5 V.

The cable uses a standard USB-A plug; does that limit charging speed or compatibility?

Yes, the USB-A interface caps output to the host port's capability, usually 5 V at 0.5–2 A, and it cannot negotiate higher voltages like USB-C Power Delivery.
