45W USB-C AC Adapter

This 45W USB-C AC adapter replaces the original charger for a wide range of Acer Chromebook models. It supports part numbers including N17Q8, N17Q9, N16Q12, N18Q3 and many others listed by the supplier. Buyers needing a direct replacement for a lost or damaged unit will find the correct fit here. It is not suitable for laptops that require a barrel connector or a higher wattage supply.

Multi-voltage output profile

The adapter delivers selectable output voltages of 5V at 3A, 9V at 3A, 12V at 3A, 15V at 3A, 18V at 2.5A and 20V at 2.25A. This range covers both 29W and 45W device requirements through a single USB-C cable. No extra cables or tips are included in the package. Devices that negotiate only proprietary charging protocols will not charge from this unit.

USB-C Power Delivery limits

The USB-C interface relies on Power Delivery negotiation between the adapter and the laptop. If a device does not support the standard PD voltages listed, charging will not start. The adapter accepts a wide AC input of 100-240V at 1.3A for global use. It cannot power devices that demand more than 45W or require a different physical connector.

Questions about this item

Does the USB-C cable or connector on this 45W adapter wear out and need replacing?

The adapter has a fixed USB-C output cable; the connector is rated for thousands of insertions, so only the cable itself would need replacement if damaged.

What limits continuous output when this 45W charger runs at 20V 2.25A all day?

The 45W maximum power rating is the first limit; sustained 20V 2.25A operation stays within that ceiling.

How much heat and fan noise does this 45W USB-C adapter produce under full load?

It has no fan and relies on passive cooling; the casing gets warm but stays within normal operating temperatures for a 45W supply.
