I believe it wants about 800mA from other posts and to give it less would be a mistake.

That is not an issue that needs consideration. If your device charges from the computer then they will charge from all usb chargers plain and simple. I agree that providing less current would be disaterous but its not an issue in usb charging, as they have to provide the current of your usb port on the computer. They all do. You can always have more then you need that again will not affect things, your device will only draw what it needs. So if you needed 50 ma then thats all it would draw. From my understanding a typical usb port provides 500 - 900ma Depending on the version of the device. This is why when we use say an unpowered hub that devices start to fail as there is more demand then what the port can supply.
So bottom line the usb wall charger will provide all the power the device needs. And seeing as the Kobo works in usb1 to usb 3 its never going to be an issue with current usb charging tech.
