Q: Is it safe to charge the Dell XPS 13 using the PowerPack 20000?
A: The PowerPack should charge your laptop properly. Besides HP, Dell is one of the pickiest vendors in terms of what 3rd party chargers they feel are compatible. Some customers have reported pop-up warning messages stating that PowerPack 20000 is an undersized charger when charging the XPS 13. If your XPS 13 charges fine after you close the message window, there's no need to worry about anything. Our charger has been rigorously tested with many laptops, including the Dell XPS 13 and proven again and again to charge safely. So rest assured that the PowerPack 20000 is both powerful and reliable and will work as well as your Dell 45W charger/AC adapter.
