What this charger powers

This 45 watt USB-C adapter supplies 5 V at 3 A, 9 V at 3 A, 15 V at 3 A and 20 V at 2.25 A. It is built for Samsung Chromebook 4, Chromebook Plus, Chromebook Pro, Galaxy Book and Galaxy Chromebook models as well as Dell Latitude, XPS, Lenovo ThinkPad, IdeaPad, Yoga and HP Chromebook devices that accept USB-C power delivery.

Steady output under load

The unit accepts 100 V to 240 V at 50 Hz to 60 Hz and maintains its four fixed voltage steps continuously. It does not throttle between profiles, so a Chromebook or ultraportable drawing the full 45 watt rating receives stable current throughout a work session.

Compact connector and travel voltage

A single USB-C plug carries both power and negotiation signals, removing the need for proprietary barrel tips. The wide input range lets the same brick operate on mains worldwide without a separate voltage selector or bulky adapter.

Questions about this item

Does the 45 W USB-C charger run hot or make noise when powering a laptop all day?

The 45 W adapter delivers 5 V 3 A, 9 V 3 A, 15 V 3 A and 20 V 2.25 A from a 100-240 V 50-60 Hz input, so it handles continuous loads within its rated output without extra cooling.

What must the laptop already have for this charger to work?

The laptop needs a USB-C port that accepts USB Power Delivery at 5 V, 9 V, 15 V or 20 V up to 45 W.

Will the 45 W charger work alongside an older 30 W or 65 W brick I keep as a spare?

Yes, the charger negotiates 5 V, 9 V, 15 V or 20 V automatically, so it can replace a 30 W unit for lighter loads or supplement a 65 W brick when 45 W is enough.
