Users whose laptops require USB-C Power Delivery, a higher wattage brick or a different barrel diameter must look elsewhere.

Questions about this item
What is the maximum continuous output power before the charger hits its thermal limit?
The adapter is rated for 45 W continuous output at 19.5 V and 2.31 A.
How much heat or fan noise does the unit produce when powering a laptop all day?
The power supply has no fan and relies on passive cooling; it runs silently and warm to the touch under full load.
Which laptop-side connector must the buyer already have for the included tips to work?
The charger includes a 4.5 mm barrel plug and a 4.5 mm to 7.4 mm conversion cable, so the laptop needs a 4.5 mm or 7.4 mm DC-in jack.
