Fervit USB-C PD Trigger Cable 5.5×2.1 mm 65/87 W 18-20 V

Trigger Cable for Barrel Laptops

This Fervit cable lets you power a laptop that uses a 5.5×2.1 mm DC jack from a USB-C Power Delivery charger. An embedded PD trigger negotiates 18 V or 20 V output, so the barrel tip delivers the voltage the laptop expects. The cable is rated for 65 W or 87 W chargers and is sold new.

Not for 5 V Devices or Undersized Chargers

It suits owners of older ultrabooks or accessories that charge through a 5.5×2.1 mm port at 18 V or 20 V. It will not work with hardware that only accepts 5 V over the same barrel size. Buyers whose USB-C charger cannot supply at least the laptop's required wattage should look at a higher-power adapter instead.

18 V or 20 V Negotiated Output

The single specification that decides fit is the negotiated voltage: the trigger requests 18 V or 20 V from the charger and passes it to the centre-positive barrel plug. If your device needs a different voltage, this cable cannot supply it.
