FAQ
Which laptops does this 90W charger fit?
Any notebook using a 19V 4.74A (90W) supply with a 7.4*5.0mm connector. The Asus, Lenovo and Toshiba model lists above cover the most common series (use Ctrl + F to search your model). Verify your original adapter voltage and connector before ordering.
Is this a genuine HP adapter?
It is a 100% brand new, OEM-grade universal replacement charger built to the ADP-90AB / ADP-90FB specification. Cross-reference the full part list (0220A1990, ADP45CB6500767, 6500920, 0335C1965 and the P/N line 2521997-105928) with your original adapter label.
Can I use it on 18.5V or 19.5V laptops?
No — this adapter outputs 19V only. Devices that require 18.5V or 19.5V (or more than 90W) need their own matching adapter; using the wrong voltage may damage the laptop. Check voltage, wattage and the 7.4*5.0mm tip before use.
What warranty is included?
A 1-year replacement warranty is included with after-sales support, and the adapter is protected against over-voltage, over-current and short circuit.
