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.

Q&A
Quick FAQ:Laptop Battery Care & Troubleshooting
- What Should I Know Before Buying a Laptop Battery Replacement?A: Before buying a laptop battery replacement, confirm your laptop’s exact model number and the part number printed on the original battery. Check the battery voltage, connector, physical dimensions, and compatibility list. Do not choose a battery based on appearance alone, because similar laptop models may use different batteries. Review the seller’s warranty, return policy, and product specifications before ordering.
- How Do I Find a Compatible Laptop Battery for My Device?A: To find a compatible laptop battery, identify your laptop’s full model number and the part number on the original battery. Compare these details with the replacement battery’s compatibility list and specifications, including voltage, connector type, and dimensions. If you are unsure, contact customer support with your laptop model and original battery part number before placing an order.
- Can I leave my laptop plugged in 24/7?Yes, the built-in TI chip prevents overcharging. Tip: To prevent long-term cell swelling, unplug and drain the battery to 40% twice a month.
- Why Is My Laptop Battery Not Charging?A: A laptop battery may not charge because of a faulty AC adapter, damaged charging port, loose connection, temperature protection, battery-health settings, or a worn-out battery. Confirm that you are using a compatible charger and inspect the cable and port for visible damage. Restart the laptop and review the manufacturer’s battery or charging settings. If the battery becomes unusually hot, swollen, or damaged, stop using it and seek professional assistance.
