Dell Inspiron 17R 5721 Power Adapter
The Dell Inspiron 17R 5721 AC adapter has two main uses, to charge any and all batteries while simultaneously providing power for the laptop. When choosing a new AC adapter, selecting the Dell OEM charger is always going to be the safest and easiest way to go. Due to the fact that one Dell adapter is probably used on other similar units, make sure you check the part number for the correct one. If your decision is to purchase a different brand charger, please check on the output of amps and voltage. A universal power adapter can be used but only if necessary.

- Most Dell AC adapters can get quite warm when plugged in for any length of time
