Power rating and connector

This 45W AC adapter delivers 19.5V at 2.31A through a 4.5mm x 3.0mm barrel connector. It accepts a universal 100-240V input at 50-60Hz and includes a three-prong AC cord. The unit carries CE, FCC and RoHS safety certifications with over-voltage, over-current and short-circuit protection.

Compatible HP notebooks

The charger fits a long list of HP 15, 17, 11, 13 and 14 inch notebooks including the 15-ba, 15-bs, 15-bw, 15-ay, 15-r, 15-g, 15-p, 15-da and 15-db series as well as select 11-d, 13-c and 14-ax models. It also matches numerous HP part numbers such as 740015-002, 741727-001, PA-1450-56HA and HSTNN-LA40. Buyers whose laptop uses a different barrel size, a USB-C power port or a higher wattage requirement should look elsewhere.

Deciding specification

The 4.5mm x 3.0mm centre-positive barrel connector is the single detail that determines whether this adapter will physically connect and supply the correct voltage. Verify that the original charger or the laptop’s DC-in jack uses this exact plug size before ordering.
