Dell Inspiron 14 3420 Power Adapter
Due to the fact that one Dell adapter powers multiple other machines, double-check the part number or model number of the adapter. The Dell Inspiron 14 3420 AC adapter is needed for two reasons, to charge up the main battery and powering the laptop. If buying off-brand, please check on the output of amps and voltage. A universal AC adapter can be used if you are desperate. When choosing a new AC adapter, selecting the Dell OEM charger is always going to be the safest and easiest way to go.
Important hints your AC adapter is on its last leg
- The laptop does not function while just using AC power
- Battery does not charge up completely
- The majority of Dell power chargers get warm when plugged in for any length of time
