usbroway 45W 19.5V 2.31A AC Adapter Laptop Charger 4.5mm x 3.0mm

SKU CH-AZ0W-9P2V9

45 W 19.5 V AC adapter with a 4.5 mm x 3.0 mm round tip for compatible Dell Inspiron and XPS laptops

  • Battery TypeLithium-Ion
  • 45 W output powers compatible Dell laptops efficiently
  • 5 V 2.31 A DC supply matches original charger specs
  • 100-240 V AC input works worldwide without a converter
  • 5 mm x 3.0 mm barrel tip fits listed Inspiron and XPS models
  • 3-prong power cord included for grounded wall connection

45W Replacement Adapter

This 45W AC adapter replaces the original charger for compatible Dell Inspiron and XPS laptops. It delivers 19.5V at 2.31A to match the factory power requirement. The unit accepts 100-240V input for worldwide use. Buyers who need a higher-wattage supply for larger models should look elsewhere.

4.5mm x 3.0mm Barrel Connector

The round 4.5mm by 3.0mm tip fits only the Dell models listed in the compatibility data. A three-prong mains cord is included for earthed outlet connection. The adapter body is a standard black plastic enclosure with no detachable cables. Build quality is consistent with OEM replacement units.

Upgrade From Lost Or Damaged Unit

This charger restores power to laptops that shipped with a 45W brick, including select Inspiron 11, 13, 14, 15 and 17 series plus XPS 12 and 13 variants. It does not add features or increase charging speed beyond the original specification. The jump is worth it only when the factory adapter has failed or been lost.
