Fonte de alimentação USB-C GaN DELL 280W CK39H para portáteis de gama alta

The DELL CK39H is a 280-watt USB-C power adapter built on gallium nitride (GaN) technology, which allows a compact form factor without sacrificing output. Unlike many high-wattage adapters that rely on proprietary connectors, this model delivers power over USB Power Delivery 3.0, making it suitable for Dell Precision 7000 series, Alienware m/x series, and XPS 16/18 notebooks that support USB-C charging at this wattage.

Highlights

• 280 W maximum output over USB-C with Power Delivery 3.0
• GaN technology keeps the adapter smaller and more efficient
• Works with AC input from 100 to 240 V at 50/60 Hz
• Integrated protection against overcurrent, overvoltage, short circuit, and overheating
