Acer TravelMate 540 Power Adapter
If buying off-brand, it is imperative to note both the volts and amps outputs. Because Acer has been known to use a single AC adapter that can be used on other units, be sure you choose the right one. The Acer TravelMate 540 power adapter is needed for two reasons, to charge the onboard battery while simultaneously providing power for the laptop. A universal power adapter can be used but only if necessary. Upon choosing a replacement AC charger, selecting the Acer OEM charger is usually going to be the safest choice.
Warnings poorly running Acer power adapter
- The laptop does not operate using just the AC power adapter
