What this cable does
This USB-C to DC cable converts Power Delivery output from a compatible charger or power bank into a barrel connector for laptop charging. It includes six interchangeable tips covering 4.0×1.7mm, 7.9×5.5mm, 7.4×5.0mm, 3.0×1.1mm, 4.0×1.35mm and 5.5×2.5mm plug sizes. The cable supports laptop inputs from 18 to 20 volts at up to 90 watts maximum. Data transfer is not supported.
Power-delivery limits
The cable itself handles up to 90 watts, but actual charging speed depends entirely on the USB-C PD source you connect. A charger or power bank must supply at least 90 watts at 20 volts to reach the cable’s rated maximum. Lower-wattage sources will charge more slowly or may not power the laptop under load. The 1.5 metre length adds minor voltage drop, so marginal supplies may struggle further.
Replaces bulky proprietary adapters
This single cable replaces multiple brand-specific AC adapters for travel or desk consolidation. The jump is worthwhile when you already carry a high-power USB-C PD charger or power bank and want to eliminate the original power brick. It is not for users who need data sync, who lack a 90-watt PD source, or whose laptop requires a tip size not listed above.
