USB-C to DC 5.5×2.1 mm cable
This Blueskysea cable converts a USB-C Power Delivery source into a 5.5 mm × 2.1 mm barrel output. It is intended for users who want to run compatible routers, CCTV units, laptops or similar gear from a PD charger or power bank. The 1.8 m length gives flexible placement.
Suits owners of 20 V PD sources needing barrel power
The cable only works when the connected PD charger or power bank can supply 20 V output. It does not change voltage and cannot be used with lower-voltage USB-C ports. Buyers whose devices require a different barrel size or who lack a 20 V PD source should look elsewhere.
Built-in PD smart chip and braided construction
An integrated PD smart chip negotiates 100 W, 90 W, 65 W or 45 W power profiles and provides protection for the connected equipment. The nylon-braided jacket with aluminium alloy shells resists pulling and abrasion while staying tangle-free. No video or data signals are carried.

Questions about this item
What PD charger output voltage must I already have for this cable to power my 20 V laptop?
You need a PD charger or power bank that can supply 20 V output; the cable itself does not change voltage, it only passes through what the source provides.
Will this cable work with my older 65 W barrel-jack power brick that lacks USB-C?
No, the USB-C plug on this cable requires a PD-capable USB-C source; it cannot connect to a legacy barrel-output adapter.
How can I confirm the cable is delivering the full 100 W my laptop requests?
Check your laptop’s battery or power settings while under load — it should report 20 V at 5 A, which equals 100 W.
