myVolts AC Adapter for HP Chromebook 11 G3 G4

SKU CH-Q40J-0NH1C

Powers HP Chromebook 11 G3 and G4 models with 19.5 V output, 100–240 V input, and includes a power cord

  • World-wide 100-240 V input suits travel
  • 5 V output matches HP Chromebook 11 G3 G4
  • Over-voltage, short-circuit and over-current protection
  • New condition with power cord cable included
  • Brand-new replacement charger tested for safety

Compatible AC Adapter

The myVolts AC adapter is a new replacement power supply for the HP Chromebook 11 G3 and 11 G4. It delivers 19.5V output and accepts worldwide input from 100-240VAC at 50/60Hz. The package includes the power cord cable for immediate use.

Replaces Original Charger

This unit replaces a lost, damaged or worn-out factory charger for the listed Chromebook models. The jump is worth it when the original adapter no longer holds a stable connection or shows signs of cable fatigue. Built-in over-voltage, short-circuit and over-current protection help safeguard the laptop during charging.

19.5V Output Headroom

The 19.5V output matches the Chromebook's requirement and comfortably handles daily charging and operation. It runs out when a device demands a different voltage or a higher current rating than this adapter provides. Buyers needing power for other laptop models or higher-wattage devices should look elsewhere.

Questions about this item

Does the barrel connector fit the HP Chromebook 11 G3 and G4 charging port?

Yes, the adapter is built as a direct replacement for the HP Chromebook 11 G3 and G4 and its barrel plug matches the laptop's DC-in jack.

What is the correct order to connect the 100-240VAC 50/60Hz input and the 19.5V output?

Plug the IEC power cord into the adapter brick first, then into the wall outlet, and finally insert the barrel tip into the Chromebook.

When should the AC adapter be replaced instead of just the power cord?

Replace the whole adapter if the brick becomes unusually hot, emits a buzzing noise, or the output voltage drifts from 19.5V despite a known-good cord.
