You are talking about a powered USB hub. Yes, they exist, but generally they only power the _device_ USB ports, i.e. only downstream devices. A hub like this must not pump power into the upstream host, because the host is normally providing power itself. The fact that the Neo can be powered by USB when in host mode is non-standard, and thus it's unlikely that you'll find an off-the-shelf cable or hub that will do this. You will most likely have to wire something up yourself.
