Acer Aspire E5-491 Power Adapter
Upon choosing a replacement adapter, choosing the Acer brand one is usually going to be the safest choice. If buying off-brand, make sure to check both the volts and amps outputs. A universal AC adapter is a possibility if yours is unavailable or backordered. The Acer Aspire E5-491 power adapter is needed for two reasons, to charge the onboard battery and to provide a source of power for the unit. Because Acer uses one power charger that is most likely used on other laptop models, be sure you choose the right one.
Red flags the Acer power adapter will soon need to be replaced
- Most Acer AC adapters will get very warm to the touch when plugged in for any length of time
- Battery does not charge up every time
- The laptop does not function while solely using the AC adapter
