Dell Inspiron 15R 5521 Power Adapter
If buying off-brand, make sure to check the output of amps and voltage. The Dell Inspiron 15R 5521 power adapter is responsible for two things, to charge the onboard battery while simultaneously providing power for the laptop. A universal power adapter is another possibility if yours is unavailable or backordered. Because Dell has been known to use a single AC adapter that can be used on other units, double-check the part number or model number of the adapter. When choosing a new adapter, selecting the Dell OEM charger is the best one to choose.
Hints your AC adapter is in dire need of a replacement
- The unit will not run while just using AC power
- The majority of Dell power chargers will get warm to the touch when plugged in for any length of time
- Battery does not charge every time
