UNITEK C14120BK-1.8M USB-C to DC 4.5x3mm Dell Charging Cable 65W PD for Dell Laptops 1.8M Chrome Pin
Charge Your Dell Laptop from Any USB‑C PD Port – Ditch the Heavy Brick
The UNITEK C14120BK-1.8M USB-C to DC Power Charging Cable lets you power your Dell laptop using any USB‑C Power Delivery charger or power bank. Say goodbye to carrying heavy proprietary chargers. This 1.8‑meter (≈6 ft) cable gives you freedom to travel light, work from coffee shops, or keep a spare charger at the office – all without the bulk.
65W Power Delivery – Smart, Fast, Efficient
Designed for Dell laptops with a 4.5 x 3.0 mm chrome pin DC connector (often called Dell "chrome tip" or "yellow tip" but actually chrome-colored), this cable supports up to 65W PD fast charging. A built‑in smart management chip automatically negotiates the correct voltage and current with your USB‑C charger, ensuring optimal speed while protecting against over‑current, over‑voltage, and overheating.
Compatible Dell Laptop Models (4.5x3mm Chrome Pin)
Works with many Dell laptops that use the chrome-colored pin barrel connector, including:
Dell XPS series (older models, e.g., XPS 13, XPS 15 before USB-C transition)
Dell Latitude series (e.g., E5450, E5470, E5480, E5550, E5570, 7xxx series)
Dell Inspiron series (select models with round chrome pin)
Dell Precision mobile workstations (older models)
Dell Vostro series
Check your laptop: The connector has a chrome (silver) metal tip, measuring approximately 4.5mm outer diameter, 3.0mm inner pin. This is not the larger 7.4mm barrel used on some older Dell laptops. If your laptop already charges via USB‑C, you don't need this cable.
Travel Light – Use Any USB‑C Charger or Power Bank
No more carrying a heavy OEM brick. Use this cable with:
A compact 65W+ USB‑C GaN charger
Your existing USB‑C laptop charger (if it offers PD)
A 45W or higher PD power bank (for on‑the‑go charging away from outlets)
Built for Durability
Pure copper conductors – excellent conductivity, minimal voltage drop
High‑quality PVC jacket – flexible, crack‑resistant, and long‑lasting
Strain relief – reinforced at both ends to prevent cable breakage
