Acer Aspire 4720Z Power Adapter
If you decide to buy an non-Acer adapter, it is imperative to note both the voltage and amperage output. Because Acer has been known to use a single AC adapter that powers multiple other machines, be certain to thoroughly note the part number that is needed for this model. When choosing a new AC adapter, choosing the Acer brand one is the best one to choose. The Acer Aspire 4720Z AC adapter provides two functions, to charge up the main battery while simultaneously providing power for the laptop. A universal power adapter is a possibility but only if necessary.
Indications your laptop charger has little time left
- Most Acer adapters will get very warm to the touch when plugged in for any length of time
- Battery does not charge completely
- The unit will not operate without the battery installed
