How does this differ from the F1? Is it intended to be an upgrade?

Unlike the F1, the UI1charger would be able to charge large-sized batteries like 20700, 21700 batteries & more.

Can these charge the Nitecore 21700/5000 Inteligent battery?

UI1 is compatible with 21700 batteries. However, we recommend charging the Nitecore i series batteries through the flashlights.

I would like the functionality of an intelligent usb single-slot quick battery charger for li-ion/ni-mh/ni-cd/imr. any ideas?

If you can do without the usb and single slot; the Eastshine S2 charger has a very informative display which I would buy again. Car plug or 110v house, has two speeds, shows charge advancement, Mah, time spent, and volts. Having those updates at a glance keeps you informed. 5 stars.
