I have a backup battery for my laptop but when I'm offline I use the laptop and the backup battery. When I go back to the outlet, I can now charge my laptop and the backup batteries at the same time, which saves a lot of time. saves a lot of time when working on the road. XPS 15 inch. The high-power cable is a thick ribbon, but the low-voltage side is the same, with a small blue light at the top of the laptop. Perfect fit for my Dell XPS I-7 15 inch 32GB 1TB device. it also charges my Dell backup battery. This is an OEM device, NOT a counterfeit.
