I'd imagine the iPad charger won't deliver more than 0.5A to any non-apple device because it doesn't support the standard USB Battery Charging spec. I know the reverse is true.

Kobo's battery percentage indicator is worse than useless. It seems to be pretty much a linear attempt to convert a voltage reading into a percentage. So it'll be nearly flat at '30%' and read higher when the charger is connected than when you disconnect it. I usually charge 40-90%. Gives a long enough life and avoiding the extremes should keep the battery going for more charge cycles (which isn't likely to matter in the case of an eReader).
I couldn't find any capacity information on the GloHD's battery except that it was '1.5Ah'. If that's at 5V than four hours is about the expected charging time from a 5v/0.5A supply (Lithium Ion batteries have to charge more slowly when they get closer to full).
