Dell WD19s UHD USB-C shop Docking

Product Name: Dell WD19s UHD USB-C shop Docking
Dell mini lap top about 3 yrs old works perfectly. I just have so many electronics now and there Apple ipads so getting rid of the things no longer used but sitting around. The only thing is I can not find the charger. I was able to charge it with my charger from my phone because shop it has a portal for it but I do not have the charger for you to keep it charged. Originally price was $299.99. I do not know how much you would pay for a replacement charger. And it's a few yrs old so Asking $70 OBO. Just message me if you have any question or would like to negotiate if you find out much a charger would be I took a pic of each side so you see what is needed. Thank you for stopping by.
