I ordered a portable power supply for my Dell Inspiron notebook. I ordered it based on research and advice from Dell representative Akavi Passah. He assured me this was the one compatible with my notebook. Once received I found the battery pack would show being fully charged but would not charge the notebook to full capacity. I placed the order 8/28/19, received it 9/01/19. I notified Akavi on 9/3/19 via email that the power pack didn't work. there was NO response, I emailed again 10/14/29, and on 10/22/19. Akavi Passah finally responded only to say he now has a different position and could no longer help me. during that time prior to his finally responding I had spend over 2 hours on phone with customer care, being jockeyed back and forth between Technical support and customer care to be told by everyone that they could not do a return as it was now ove 30 days since order, and that I could only deal with the agent who sold product. you can see how well that went! I ended up disputing the charge to Dell, with was another long process, only to have Dell tell the credit card that they would not honor a return and I could not get a replacement as there was not a product that would work. I ended up having to pay $150 for a product i cant use. I am totally discussed with Dell and plant to avoid future products. their customer care is really awful, people are hard to understand, very poor communication due to language. I originally chose to deal directly with Dell thinking they would have the correct product and be able to advice me correctly--guess not!
