Napájací zdroj Dell 90W USB Type-C 0TDK33 – 90W USB-C napájací zdroj pre notebook

Dell 90W USB Type-C 0TDK33 is a 90-watt AC adapter designed to deliver mains power to laptops and USB-C devices that support USB Power Delivery. The compact power supply includes an integrated USB-C cable and a plug suitable for standard wall outlets, allowing charging and operation of compatible notebooks, docking stations and USB-C peripherals. The adapter converts AC mains input to a stable 20V/4.5A (or negotiated PD profile) output to maintain system performance during charging and use.

Advantages

The adapter provides a reliable 90W power output suitable for most mainstream laptops and larger ultrabooks that accept USB-C charging. Its compact, lightweight design and integrated cable reduce the number of separate accessories to carry. Built-in power delivery negotiation ensures automatic voltage and current adjustment to match the connected device within supported PD profiles. The adapter includes over-voltage, over-current and short-circuit protection to help safeguard connected equipment.

Suitable for

• Charging and powering USB-C compatible laptops and ultrabooks
• Powering docking stations and USB-C hubs that draw up to 90W
• Charging tablets and high-capacity mobile devices that accept USB Power Delivery
• Use at home, in the office or while travelling where a compact mains adapter is required

Key specifications

• Output power: 90 watts (maximum)
• Output interface: USB Type-C (integrated cable)
• Power delivery: USB Power Delivery compatible with negotiated voltage/current profiles
• Typical output voltage/current: up to 20V at ~4.5A depending on PD negotiation
• Input: AC mains (standard wall outlet)
• Design: compact form factor with integrated cable and strain relief
• Protection features: over-voltage, over-current and short-circuit protection

How to use

Connect the adapter to a compatible AC wall outlet, then plug the integrated USB-C connector into the USB-C charging port of the laptop or device. The adapter and the device will negotiate the appropriate voltage and current automatically via USB Power Delivery; charging will begin once negotiation completes. For best results, use the adapter with devices that explicitly support USB-C PD and ensure the device firmware supports external power sources for operation while charging.

Recommendations

Use the adapter on a stable, well-ventilated surface and avoid covering it during operation. Inspect the integrated cable and connector regularly for damage; do not use the adapter if the cable or connector is frayed or damaged. For optimal battery health, follow the laptop manufacturer’s guidance on charging practices and avoid prolonged exposure to high ambient temperatures while charging.
