Dell and many other makers had to implement a new 3 wire charger system so you can no longer hook up a batter with the right Volts to a Dell. Since this will have to use Dell's proprietary 3 wire signaling system you must look to Dell for such a thing.
I am having trouble finding a Battery Pack for my Dell laptop ..... I connected the Crave 50000mAh PowerPack to my Dell laptop today, but got an Error Message saying the battery pack was not compatible with my laptop. Must have at least 65W to power my laptop. My Dell laptop requires 19.5v. I think 20v would still be ok ? But not sure if only 19v would be sufficient ... ?
I have been searching on Amazon and Google .... and have found many battery packs and portable generators (that do not need to be plugged in to run devices), but do not know which ones, if any, will run my Dell laptop ....
Can you help me find the correct unit to power my laptop while camping ... ? I need something with enough juice to last several days .... also with several USB ports, at least one AC port.
