Depends on the the Qi adaptor bought. In theory the same speed is possible, but most deliver about 1/3rd of what the Sage can charge at, so approximately 150 minutes vs 50 minutes for a charge from flat.

No magic, just physics and mathematics. With a suitable 2A charger (not all), the Sage seems to take about 1500mA. Most slim 3rd party Qi adaptors are 500mA (but could be less). Required alignment accuracy with mat/dock will vary with charger design, not so much the receiver. It's inductive "contactless" rather than actually "radio" wireless, so a metal back damps the power and any separation or mis-alignent also drops the power.

I was also thinking that a €5 book stand and €3 cable 2m long with some modelling compound would make a dock for any ereader or tablet (obviously a particular dock would only suit one gadget with connection at side, but might suit several with socket on an end).
