Universal 5V USB power cable with nine interchangeable DC connectors for lamps, routers, fans and other low-voltage devices
The PK-549B cable converts any standard USB port into a 5 V DC supply for small electronics. Nine interchangeable tips cover barrel and pin connectors from 2.5 mm up to 6.4 mm diameter. Pure copper conductors and a durable black jacket provide stable current delivery. It is aimed at owners of moon lamps, routers, mini fans, speakers and similar 5 V gear who want one compact lead for travel or desk use.
Users who power several devices with different barrel sizes benefit from the included adapter set. The cable draws power from power banks, wall chargers, car ports or laptop sockets. Devices that require voltages other than 5 V or need proprietary multi-pin connectors cannot use this cord. Buyers who need a fixed single-tip cable or higher current ratings should look elsewhere.
The cable terminates in a 5.5 × 2.1 mm jack and ships with eight additional barrel plugs plus one 2.5 mm pin adapter. Listed tip diameters are 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 and 3.5 × 1.35 mm. Matching the device’s exact connector size and polarity is the deciding factor for compatibility.

Any standard USB-A port such as a power bank, wall charger, car charger or computer port supplies the 5 V input the cable requires.
The set ships with a 5.5 × 2.1 mm connector plus eight other sizes ranging from 2.5 mm to 6.4 × 4.4 mm, covering most legacy 5 V router jacks.
The connected device should power on or show its charging indicator; the pure-copper conductor provides stable 5 V DC transmission when the correct tip is seated.
