So what's the deal on charging these? Are you stuck with the 5V 2.5 Amps charger with the round plug, or can you use any of the USB wall chargers out there, and if so which ones? How about some converter from a wall charge USB to the round plug. Still 5V but lower amps.

I don't have an IdeaPad, but FWIW I regularly charge my Nook Tablet and Nexus 7 (as I also do with my other handheld electronics) from a powered-USB Hub (which is connected to my PC), which takes a lot longer than when I use the NT/N7 original USB wall-chargers (5V/2A) -- a a full charge overnight vs. a full charge in a few hours.
If you're looking for USB wall-charger you might want to give these 5V/2A chargers a try.
