usbroway 90W 65W AC Adapter for Dell Latitude Inspiron Chromebook

SKU CH-ZRMT-CX4YG

A 90W and 65W charger compatible with many Dell Latitude, Inspiron and Chromebook models, supplied with a power cord

  • Battery typeLithium-Ion
  • Charges at 90W for power-hungry Dell laptops
  • Also delivers 65W for compatible Dell models
  • Works with Latitude, Inspiron and Chromebook 11 series
  • Includes overheat, short-circuit and overcurrent protection
  • Supplied with AC adapter and power cord

What this charger replaces

This 90W and 65W AC adapter replaces the original Dell power supply for a long list of Latitude, Inspiron and Chromebook models. It matches part numbers such as LA90PM111, HA65NS5-00, HK65NM130 and LA65NM130. The unit ships with a power cord so it is ready to use immediately.

When the upgrade makes sense

Swap to this charger when the factory brick is lost, damaged or no longer holds a stable output. The dual 90W and 65W rating covers both higher-draw Latitude systems and lower-draw Inspiron or Chromebook units, removing the need to keep two separate adapters. Built-in overheat, short-circuit and overcurrent protection helps safeguard the laptop during daily charging.

Who should buy and who should not

This adapter suits owners of the listed Dell Latitude, Inspiron and Chromebook models who need a direct replacement with the same connector and voltage. It is not for laptops that require a different output voltage, a proprietary barrel size or a USB-C power delivery profile. Buyers with non-Dell hardware or models outside the compatibility list should look elsewhere.
