This is Logitech's top-end keyboard case, and it does have premium features: it automatically pairs with the iPad after snapping into position against a magnet above the keyboard. This saves battery life and means that the case, when folded open into tablet-viewing mode, deactivates the keyboard. Keys underneath won't work if accidentally pressed by the case's top edge.
The FabricSkin recharges via Micro-USB, and comes with a cable. A full charge should last at least three months, according to Logitech; I haven't spent anywhere near that time with the case, so I can't vouch for that battery life.
There's not a lot holding the iPad Air in this case: just two thin corner guards that you slide it into to position the iPad into place. It's nearly naked otherwise, sandwiched between the keyboard and top half. That mean the iPad is a little less protected, but with the case closed it feels ready to buffer against impact. It still weighs 0.94 pound, however, nearly as much as the iPad Air itself. You're doubling your travel weight, but adding a case and a keyboard.
This case is for someone who loves having a splash- and spill-resistant keyboard. Maybe someone with kids. It's a good case, but for this price it's not great. And better alternatives exist. More than anything, I just wish Logitech hadn't messed with its already-great keyboard formula.
