Acer Aspire E5-521 Power Adapter
The Acer Aspire E5-521 AC adapter is needed for two reasons, to charge up the main battery and to provide a source of power for the unit. Because Acer uses one power charger that is probably used on other similar units, be certain to thoroughly note the part number that is needed for this model. A universal AC adapter is another possibility if you absolutely need to. If your decision is to purchase a different brand charger, please check on the output of amps and voltage. When choosing a new AC charger, choosing the Acer brand one is always going to be the safest and easiest way to go.
Key symptoms of a laboring AC adapter
- The unit will not work while just using AC power
- Battery does not charge all the time
- Most Acer adapters will get warm to the touch when they are plugged in for a period of time
