Acer Extensa 390 Power Adapter
If your decision is to purchase a different brand charger, it is imperative to note both the volts and amps outputs. When choosing a new AC charger, the actual Acer brand is usually going to be the safest choice. The Acer Extensa 390 power adapter provides two functions, to charge any and all batteries and powering the laptop. A universal AC adapter is a possibility if yours is unavailable or backordered. Because Acer has been known to use a single AC adapter that is probably used on other similar units, be sure you choose the right one.
How can I tell if my laptop charger needs replacing?
- The laptop does not operate while just using AC power
- Battery does not charge up whatsoever
- Most Acer adapters will get warm to the touch when they are plugged in for a period of time
