45W USB-C Charger for Acer Chromebook Spin
This 45W USB-C power adapter is built for owners of Acer Chromebook Spin and Swift models who need a replacement or spare charger. It delivers up to 45W through a single USB-C connector and carries the part numbers PA-1450-78 and A16-045N1A. The unit is new and ready for daily use.
Critical voltage match for Spin and Swift models
The charger must supply 20V at 2.25A to meet the 45W requirement of the listed Chromebook Spin and Swift devices. Lower voltage rails such as 5V, 9V, 12V, 15V and 18V are also present for negotiation, but the 20V rail is the one that powers the laptop at full speed. If your device expects a different maximum voltage, this adapter will not charge it correctly.
Steady output with built-in protection circuits
Over-voltage, over-current, short-circuit and over-temperature safeguards keep the power delivery stable during long charging sessions. The adapter maintains its rated 45W continuously without throttling or shutting down under normal thermal conditions.

Questions about this item
How much power does the 45W rating actually deliver to my Chromebook?
The charger supplies up to 45W through USB-C Power Delivery with selectable voltages of 5V at 3A, 9V at 3A, 12V at 3A, 15V at 3A, 18V at 2.5A and 20V at 2.25A, so the laptop draws the level it negotiates.
What does the USB-C interface limit in real use?
The USB-C port caps output at 45W maximum and negotiates voltage steps of 5V, 9V, 12V, 15V, 18V and 20V, so any device limited to lower PD profiles will charge at its own ceiling.
What physical connector and cable length do I need to fit my Acer Spin?
It uses a USB-C plug on a fixed cable and accepts AC 100-240V 1.3A input, so any standard wall outlet works without an adapter.
