The adapter handles input from 100 to 240 V, which covers the standard mains voltages used in most countries. You can keep it in your bag for business trips or holidays and plug it in at the hotel just as you would at home. You may still need a plug adapter for some sockets.
With a 19 V output, the U90W-01 delivers the voltage its rated devices expect. Because it comes from Asus, it is a sensible pick when you would rather not gamble on an unbranded replacement. Check that your device's original charger also specifies 19 V before ordering.
Weighing 0.267 kg, the adapter will not noticeably weigh down a laptop bag. Its plain black finish blends in on a desk and looks neat next to most laptops, so it works equally well as a permanent office charger or a backup you keep in your backpack.
This adapter suits Asus laptop owners who need a replacement or a second charger, frequent travellers, students who carry their laptop between home and campus, and offices or IT departments stocking spare power supplies.
