Alphacool 90W 19.5V 4.62A Circular Charger 2 in 1 Accessory

SKU CH-8KZ2-NDTSE

90 W circular power adapter with included cord for compatible Dell Inspiron 2-in-1 laptops

  • UL certified safety meets national gold standard
  • 90W 19.5V 4.62A output powers compatible Dell models
  • Circular connector fits listed Inspiron 15 17 and AIO 2 in 1 units
  • Includes AC charger and power cord for immediate use
  • 12 month manufacturer warranty backs the product

Purpose and fit

This 90 W circular charger powers Dell Inspiron 15 and 17 models including the 5400 5401 5490 5491 7500 7501 7590 7591 7790 7791 7700 and AIO 2 in 1 variants W24C002 P83F P84F. It supplies 19.5 V at 4.62 A through a round connector and includes the AC adapter plus a power cord. Buyers needing more than 90 W should look elsewhere.

Sustained load behaviour

The adapter delivers its rated 90 W continuously under normal laptop operation without exceeding its thermal design. UL certification confirms the unit meets recognised electrical safety standards for prolonged use. No additional cooling or derating is required within the specified output range.

Upgrade context

It replaces a lost or failed original charger for the listed Dell models and restores full charging speed where the previous unit was damaged or missing. The jump is worthwhile when the existing supply no longer provides 19.5 V at 4.62 A or the connector is worn. Systems requiring higher wattage are not compatible.
