USB-C to DC 7.4*5.0mm charging cable

This 1.8 metre cable converts a USB-C power source into a DC 7.4 by 5.0 millimetre barrel connector for laptop charging. It targets users who want to power a compatible laptop from a high-wattage USB-C charger instead of the original brick. The cable integrates a PD trigger chip to negotiate the required voltage. It is not for laptops that use a different barrel size or a proprietary connector.

Built-in PD trigger and protocol support

The cable embeds a 100 watt 20 volt 6 ampere PD emulator trigger at the USB-C male end. It supports QC 2.0, QC 3.0 and USB PD negotiation so the charger can deliver the correct power profile. The Type-C charger used must be rated higher than the DC output the laptop requires. No separate adapter or software is needed; the trigger handles the handshake automatically.

20 volt 5 ampere maximum output

The cable delivers up to 20 volts at 5 amperes for a 100 watt maximum, and also handles 66 watt output profiles. This single specification decides compatibility: the laptop must accept 20 volts through a 7.4 by 5.0 millimetre DC jack and draw no more than 5 amperes. If the laptop requires a different voltage, a higher current or a different jack size, this cable will not work.

Questions about this item

Will the built-in PD trigger chip need replacement after heavy use?

The cable integrates a 100W DC 20V 6A PD emulator trigger at the Type-C male end with no user-serviceable parts, so the trigger is not designed to be replaced separately.

What limits the 65W output during continuous charging?

The DC 7.4×5.0 mm male output is rated for 20V 5A up to 100W maximum, and the Type-C charger must supply more power than the laptop draws to sustain 65W.

Does the 1.8 m cable get hot or draw extra power when run all day?

The cable carries up to 100W at 20V 5A through its 1.8 m length; heat depends on the charger and laptop load, and the cable itself adds no active power draw.
