19V AC Adapter for Asus Vivobook Laptops

This 19V AC adapter replaces the original charger for several Asus Vivobook models including D550MA, X551MA, F501 and S551LB series. It ships with a power cord cable and accepts worldwide input voltage from 100 to 240VAC at 50 or 60Hz. The unit is brand new and built as a compatible replacement power supply.

Sustained Load Behaviour

The adapter delivers a steady 19V output with over voltage protection, short circuit protection and over current protection active during continuous operation. These safety features engage automatically when the power draw approaches the adapter's limits under prolonged use. The wide input range allows stable performance across different mains supplies without manual switching.

Installation and Common Issues

Connection is straightforward: plug the barrel connector into the laptop and the IEC cord into a wall outlet. The most frequent problem is selecting a charger with the wrong tip size or polarity for a specific Vivobook sub-model, so verifying the exact model number before ordering avoids returns. No driver installation or configuration is required.

Questions about this item

How much heat does the 19V adapter produce when powering a Vivobook D550MA all day?

The adapter includes over-voltage, over-current and short-circuit protection to limit heat build-up during continuous operation.

What cable must I already have to connect this adapter to the mains?

A standard IEC C7 figure-8 power cord is included in the box, so no separate mains cable is required.

Will this 19V supply safely charge my older Vivobook X551MA alongside the newer D550MA?

Yes, the 100-240VAC input and 19V output match the requirements for both the X551MA and D550MA series.
