myVolts 45W AC Adapter 19V 1.75A-2.37A 4.0mm*1.35mm

SKU CH-YKMH-94T9A

A 45W laptop charger delivering 19V at 1.75A-2.37A with a 4.0mm*1.35mm tip and an included 5.5mm*2.5mm converter cable for compatible Asus models

  • Delivers 45W or 33W output for flexible charging
  • 19V at 1.75A–2.37A matches listed ASUS requirements
  • 0mm × 1.35mm barrel plug fits many ZenBook and VivoBook models
  • Includes 4.0mm to 5.5mm × 2.5mm adapter cable for wider compatibility
  • DC cable wraps around adapter body for tidy travel storage

Travel-Ready Power Supply

This 45W AC adapter delivers 19V at up to 2.37A for a wide range of ASUS ZenBook, VivoBook and Taichi ultraportables. The foldable plug and self-wrapping DC cable keep the unit compact inside a bag, making it suited to professionals who move between desks daily.

Steady Output Under Load

The supply maintains a stable 19V rail across the 33W to 45W range, so sustained workloads such as video playback or long compile sessions do not trigger voltage droop. Thermal protection engages only if the unit exceeds its design envelope, preserving both the adapter and the laptop's charging circuit.

Durable Connector System

A 4.0mm × 1.35mm barrel tip fits the listed models directly, while the included 5.5mm × 2.5mm conversion cable extends compatibility to older ASUS units without adapter swaps. The strain-relieved cable junction resists repeated bending, and the foldable AC pins retract flush to avoid snagging on other gear.

Questions about this item

How warm does the 45W 19V adapter get when left plugged in all day?

The unit runs at typical wall-charger temperatures; the foldable plug and wrap-around DC cable design keep airflow clear during continuous use.

What must I already own for this charger to power my ASUS laptop?

You need an ASUS model that accepts a 4.0mm × 1.35mm barrel tip; the included 5.5mm × 2.5mm converter cable covers laptops with the larger jack.

Will the 33W 1.75A mode work reliably on my older UX305 that originally shipped with a 45W brick?

Yes — the adapter auto-switches between 1.75A and 2.37A at 19V, so it matches the UX305’s 33W and 45W requirements without manual selection.
