Dell Latitude E5550 Power Adapter
If you decide to buy an non-Dell adapter, make sure to check the output of amps and voltage. Due to the fact that one Dell adapter powers multiple other machines, be certain you select the correct one for the Latitude E5550 model. The Dell Latitude E5550 AC adapter has two main uses, to charge any and all batteries and to provide a source of power for the unit. A universal power adapter can be used if you absolutely need to. When purchasing a replacement charger, the actual Dell brand is usually going to be the safest choice.
Clues to watch for to know your AC adapter will not last the year
- Your Dell battery refuses to charge up completely
- Most Dell adapters will get very warm to the touch when plugged in for 10 minutes or more
- The unit will not run using just the AC power adapter
