The list might be incomplete because it is difficult to collect all information at one time. If you are not sure of your choice, please type the part number and model number as special comment in our shipping form at the time of checkout. We will ship you the correct adapter based on your input.
To get a correct adapter replacement, you must make sure the adapter connector tip is right. Please check the tip size and compare the tip shape with your original device. Contact us if you have any questions, thanks

Laptop Adapter FAQ2: My original has different output voltage and amperage from yours, does your replacement adapter really work?

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. more ...

DC790A adapters tips:
All of us want to prolong our Acer laptop AC Adapter's life. What should we do to prolong the laptop AC Adapter's life? here is some brief guide to extend your li-ion DC790A AC Adapter's life..
You must initially give the AC Adapter a 12-14 hour charge on the proper charger.Try to use the home charger more often than the cigarette lighter charger.
Not in the high temperature environment for charging Acer Battery ,make sure the environment temperature is suitable temperature.
Lithium-ion Battery prefers a partial rather than a full discharge,frequent full discharges should be avoided when possible.
Do not use higher than its threshold voltage to charge the DC790A AC Adapter ,as it would become unsafe.
purchase spare lithium-ion laptop batteries for later use if your AC Adapter series get weak over times.
Keep the rechareable Acer AC Adapter cool. Avoid a hot situation. For prolonged storage, keep the DC790A at a 40% charge level.
Do not short-circuit. A short-circuit may cause severe damage to the AC Adapter.
Through the above Suggestions, you can take better care of your DC790A AC Adapter replacement. You need them for your daily life.
How to Charging the Li-ion Laptop Battery?
Claims of fast charging a Li-ion Laptop Battery in one hour or less usually results in lower charge levels. Such a charger simply eliminates stage two and goes directly into 'ready' once the voltage threshold is reached at the end of stage one. The charge level at this point is about 70%. The topping charge typically takes twice as long as the initial charge.
Depending on the Acer laptop AC adapter and the self discharge of the battery, a topping charge may be implemented once every 500 hours or 20 days. Typically, the charge kicks in when the open terminal voltage drops to 4.05 volts per cell and turns off when it reaches 4.20V/cell.
No trickle charge is applied because the Li-ion laptop battery for laptop is unable to absorb overcharge. Trickle charge could cause plating of metallic lithium, a condition that makes the cell unstable. Instead, a brief topping charge is applied to compensate for the small amount of self-discharge the DC790A adapter and its protective circuit consume.
