45W USB-C Chromebook Charger

This 45W USB-C power adapter delivers up to 45 watts for Chromebooks and compatible laptops from brands such as HP and Google. It accepts a universal 100-240V input at 50-60Hz and connects via a USB-C plug. The package includes a power cord, the adapter unit and a manual with a combined length of about 10 feet.

Sustained Output Across Voltage Steps

The adapter maintains continuous delivery at 5V 3A, 9V 3A, 12V 3A and 15V 3A, then steps to 18V 2.25A and 20V 2.25A for higher-voltage devices. This multi-profile design lets the unit run at its rated 45W across the full range without dropping to a lower burst limit. The 1.3A input draw stays steady while the output rails are loaded.

USB-C Power Delivery Practical Limits

USB-C Power Delivery negotiates the highest voltage the connected device supports, so the 20V 2.25A rail is only used when the laptop requests it. Cables rated below 3A or 20V will restrict the charger to a lower profile, reducing the available power. The 100-240V input covers global mains standards, but the adapter cannot exceed its 45W ceiling even if the source can supply more.

Questions about this item

How much heat or fan noise does the 45 W USB-C adapter produce when it runs all day?

The adapter has no fan and operates silently; it only becomes warm to the touch during continuous 45 W output.

What cable or plug must I already own to use this charger?

A detachable power cord is included, so no extra cable is required — just plug the USB-C connector into the laptop.

Will the 18 V and 20 V outputs work safely with my older Chromebook that only accepts 12 V?

Yes — the charger negotiates voltage automatically and will supply only the 5 V, 9 V or 12 V levels that the older device requests.
