Acer Aspire 1820PT Power Adapter
The Acer Aspire 1820PT AC adapter is responsible for two things, to charge up the main battery and powering the laptop. If buying off-brand, it is imperative to note both the voltage and amperage output. A universal power adapter is a possibility if you are desperate. 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. When choosing a new AC adapter, selecting the Acer OEM charger will probably be the safest way to go.
Some warnings your laptop charger is failing

- The unit will not work while solely using the AC adapter
