Harry Potter was not the first book series to have wand-wielding magicians, and it won't be the last. The best thing to do is just give your own world's wands an identity. My own world has wands/staffs essentially being the same device, but with different firepower/augmentation of abilities. Mages can perform magic without them (and indeed, a living mage is required for a wand/staff to be of any use at all), but wands act as conduits and enhancers of existing magic. They are treated like technology, having 'nodes' that, depending on the material, can enhance different sorts of magic (Nasite enhances 'chaotic' magic like pyromancy and Norvite enhances 'orderly' magic like cryomancy). Basically, you need to analyse the tone of your fantasy 'verse, and make the wands fit accordingly, fear of Harry Potter be damned.
