WAWEIS P31 90W AC Adapter laptop battery

SKU CH-G7TW-BYS35 MPN P31

Replacement 90 W AC adapter with 10 ft cord, 100–240 V input and full safety protections

  • World-wide 100–240 V input works anywhere
  • 10 ft total cord length gives flexible placement
  • Over-current, over-voltage and short-circuit protection keeps hardware safe
  • FCC, CE and RoHS certified for regulatory compliance
  • 100 % compatible replacement for listed Asus models

Universal 90 W replacement adapter

This 90 W AC adapter replaces the original charger for Asus notebook models P31, P31F, P31SD, P41, P41SV and P43. It accepts worldwide input voltage from 100 to 240 VAC at 50 or 60 Hz. The unit ships with a 10 ft power cord for flexible placement.

Built-in safety protections

Over current protection, over voltage protection, short circuit protection and total power protection guard the laptop during charging. A smart chip adds overheating protection while high-quality wires and isolation materials reduce interference. The adapter meets FCC, CE and RoHS certification requirements.

Upgrade from a lost or failing charger

The adapter restores full charging capability when the original supply is lost, damaged or no longer holds a stable output. It is not suitable for laptops that require a higher wattage rating or a different connector type. Buyers needing multiple simultaneous outputs or a USB-C power delivery profile should look elsewhere.

Questions about this item

How do I install this 90W adapter and what step is often missed?

Plug the mains cord into a 100-240VAC 50/60Hz outlet, connect the DC plug to the laptop, and ensure the connector polarity matches the Asus P31, P31F, P31SD, P41, P41SV or P43 socket — the polarity check is the step most people skip.

What maintenance or replacement will this charger need later?

The unit has no user-serviceable parts; if the 10 ft cable sheath frays or the smart-chip overheating protection trips repeatedly, replace the whole adapter rather than attempting repair.

What limit appears first during sustained use?

Continuous full-load operation will trigger the over-current or over-voltage protection circuits before any thermal throttle, cutting output until the adapter cools.
