45W HP charger for 15-inch models
This 45W AC adapter delivers 19.5V at 2.31A through a 4.5mm by 3.0mm barrel connector. It suits HP Pavilion x360, Envy x360 and standard 15-inch laptops from the 15-bs, 15-cp, 15-cs, 15-cr, 15-cw, 15-da, 15-db, 15-dy, 15-ef, 15-eh and 15-gw series. Buyers needing a higher-wattage unit for larger workstations should look elsewhere.
Thermals and power draw
The adapter accepts AC 100-240V at 50-60Hz input, making it usable worldwide without a voltage converter. Rated output is 45W, so normal operation stays within a modest power envelope. No active cooling is present, so the unit runs silently.

Questions about this item
How do I connect the 4.5mm*3.0mm barrel plug without damaging the laptop port?
Align the centre pin and outer sleeve straight on, then push until it seats firmly — forcing it at an angle bends the internal contacts.
Which part of this 45W adapter wears out first and needs replacing?
The output cable near the barrel plug frays from repeated bending; the brick itself has no user-serviceable parts.
What limits continuous charging at 19.5V 2.31A during heavy workloads?
The 45W power ceiling — sustained loads above that cause the adapter to throttle or shut down until it cools.
