This is a wall mount for a Shark hand held vacuum with a charge port. This should fit the following models CH901, CH950, CH951, and CH955.
I was surprised to find that this model does not come with the wall mount, same issue with the more expensive version. When I went to the sharkaccessories.com site not only did I find they charge $29.95 for this (50% cost of the vacuum) but they didn't have it in stock. So I took a few hours to design this version ;-)
