USB-C PD to 5.5×2.1mm DC cable
This cable converts a USB-C Power Delivery source into a 5.5 mm by 2.1 mm barrel output. It negotiates 19 V or 20 V from compatible PD chargers or power banks and delivers up to 100 W. The built-in smart trigger chip handles the voltage handshake automatically.
Who this suits and who it does not
It suits owners of mini laptops, monitors, routers or CCTV gear that use a 5.5×2.1 mm DC jack and need portable power from a PD bank. It will not work for devices that require a different barrel size, a voltage other than 19 V or 20 V, or more than 100 W. Buyers who need simultaneous data transfer should look elsewhere.
Installation and common pitfalls
Plug the USB-C end into a PD-capable charger or power bank and the barrel plug into the device; no drivers are required. The most common issue is using a charger that cannot supply 19 V or 20 V PD profiles, which leaves the cable inactive. Confirm the device’s voltage and polarity before connecting to avoid mismatch.

Questions about this item
What USB-C power source do I need to use this 5.5×2.1mm adapter cable?
You need a USB-C PD power bank or PD charger that can negotiate 19V or 20V output. The built-in smart PD trigger chip requests those voltages up to the 100W limit.
Will this cable safely power my older 19V laptop that uses a 5.5mm barrel jack?
Yes, if the laptop requires 19V or 20V and uses a 5.5mm × 2.1mm DC jack. The cable negotiates the correct voltage and includes overvoltage, overcurrent and short-circuit protection.
How can I confirm the cable is delivering the right voltage after I plug it in?
Check that your device powers on and operates normally. The PD trigger chip only enables output after successful 19V or 20V negotiation, so normal operation means the voltage is correct.
