Good luck let us know how it works out.

This is correct assuming the USB AC adapter has a built-in current limiter. The PC USB port is limited in its output, so even though the Kobo is looking for 700 mA, it only gets what the port can supply. If the adapter does not have a current limiting circuit, it could potentially overheat if it is rated at less than the Kobo's input rating. I'm sure there are some cheap USB AC adapters out there that are at risk of overheating.
On a side note, this means that any adapter rated at 700 mA or higher will charge the Kobo in the same amount of time. If you use an adapter rated lower than 700 mA, it will take longer, with the length of time proportional to the output rating of the adapter.
