19V 2.63A 50W AC Power Adapter 5.5x1.7mm DC Tip Model ADS-65BI-19-3 Replacement Charger Compatible with APD DA-50F19 HP 2711X 2511X LED Monitor Acer Benq LCD Display Power Supply Cord

This switching AC-DC power adapter is a fully matched replacement power supply for LED/LCD desktop monitors, labeled with model ADS-65BI-19-3 and perfectly cross-compatible with the APD DA-50F19 original charger. It delivers stable regulated DC 19V 2.63A (50W) output through a widely used 5.5mm outer diameter × 1.7mm inner diameter center-positive DC barrel connector, which physically plugs seamlessly into the power jack of target display devices.

The adapter adopts universal global AC input ranging from 100V to 240V at 50/60Hz frequency, supporting power grids in most countries and regions. The internal high-efficiency switching power circuit meets Level VI energy efficiency standard, effectively reducing idle power consumption and operational heating during long-term non-stop working status for monitors. Comprehensive safety protection modules including over-voltage protection (OVP), over-current protection (OCP), over-temperature protection (OTP) and short-circuit protection are integrated inside the PCB board, which automatically cuts off power output in abnormal conditions to safeguard your expensive monitor mainboard and backlight panel from burnout damage.

It has precise compatibility lists for mainstream monitor brands:

1. HP: 2711X, 2511X, Pavilion 2511X, 27VX LED monitors
2. APD original part number: DA-50F19
3. Additional compatible displays: Multiple Acer LCD monitors, Benq EW2740 / EW2740L and VYE MINI-VS37 devices

The outer casing is made of high-strength flame-retardant engineering plastic with anti-aging and pressure-resistant performance. The DC output wire is designed with molded strain relief at the joint to prevent internal copper wire breakage caused by frequent bending, pulling and twisting. Built-in EMI electromagnetic shielding suppresses circuit ripple and electrical interference, eliminating screen flicker, color aberration and display signal instability issues during monitor operation.

Complete plug-and-play setup without driver installation, each set includes 1 main power adapter and one matched AC input power cord, optional US/EU/UK/AU plug standards for different regional wall sockets. Widely used for broken original charger replacement, monitor maintenance repair, spare power backup for office desktop displays and retail after-sales accessory inventory, offering stable, safe and cost-effective power solution for 50W-class LED monitors.
