If by normal you mean by Boss or Digitech or Zoom, 1Spot has higher current capacities, so you can run more pedals.
If by normal you mean those you can buy at hardware shops or pasar malams, 1Spot as well as the previously mentioned adapters are regulated, they provide a steady 9V regardless of the circuit connected. Unregulated adapters provide you with "around" 9V, depending on what it's plugged into.
