Fixed-voltage trigger cable

This 4 ft USB-C trigger cable contains an e-mark chip and requests a fixed 9 V output through PD 2.0, PD 3.0 or QC 4.0 negotiation. It terminates in a 5.5 × 2.5 mm centre-positive barrel connector and uses 18 AWG copper conductors rated for 5 A. The 1.2 m length suits bench power and portable device applications.

Makers and repair technicians

Builders powering 9 V router boards, synth modules or vintage gear from a PD power bank will find this a compact solution. Users whose equipment needs a different fixed voltage or an adjustable trigger should look elsewhere because this cable only requests 9 V.

9 V fixed PD trigger

The cable requests exactly 9 V from the source; if the charger does not offer that voltage the negotiation falls back to the next lowest level the supply provides. No other voltage can be selected with this model.

Questions about this item

What does the 9 V PD trigger actually deliver when I plug it into my laptop charger?

The cable negotiates 9 V from a USB-C PD 2.0 or 3.0 source and passes that voltage to the 5.5 × 2.5 mm barrel plug, provided the charger supports 9 V; otherwise it falls back to the next lower voltage the charger offers.

Which USB-C power standards does the e-mark chip support for 5 A operation?

The built-in e-mark chip enables 5 A current with USB Power Delivery 2.0 and 3.0 as well as Quick Charge 4.0, so any compatible charger can deliver the full 5 A through the 18 AWG copper conductors.

Will the 4 ft cable and barrel connector fit my router’s 5.5 mm jack?

Yes — the cable ends in a centre-positive 5.5 × 2.5 mm barrel plug and measures 4 ft (1.2 m), matching the common router and device jack size.
