Sure, we guarantee our replacement adapter work with your laptop or netbook if your adapter part number or laptop model number is included in our compatible list. Our adapter has +/- 1 voltage allowance. For example, our 19V adapter automatically switches its output voltage to 18.5V, 19V, 19.5V, or 20V accordingly when it is plugged in. It will be no problem if the output current (A - Amperage) of your original adapter is smaller than ours. For example, our 90W adapter (19V x 4.73A) can replace your genuine 65W (19V x 3.42A) or 75W (19V x 3.95A) adapter without any problems as long as they have same output voltage and connector tip. For tip size and shape, you can put your mouse on the adapter picture in product page to get a close-up image and read the details. Higher power adapter has no impact on your laptop because the laptop drawsbsas as many amps and watts as it needs while the adapter just provides as much power as the laptop draws.
