I would purchase a 220v charger here, however, I am headed back home to the states later this year. I would hate to buy a 220v charger here, only to have to sell it, and purchase a new charger when I get home. So... anyone with a wireless charger, can you tell me if your particular charger is dual voltage?
The Qi chargers themselves are universal and don't use the 110v - 220v. So don't worry about that and pick up whatever Qi charger you want. They are all DC 5V 1.5A - 2A input. They generally just come with the charging plate and a USB cable (unless you buy for example the official Nexus 5 wireless charger which also includes the power adapter that supports 100 - 240v anyway). So you can plug the Qi charger using USB into a PC if you really need to (charges slower though).
What you will need to consider is the AC adapter/wall wart (what plugs into the wall, with a USB port or micro USB cable attached) that you usually buy separately (make sure it is 2A output). The AC adapter is what you need to make sure supports 100 - 240v. Most USB wall adapters are travel adapters by design, so they already support 100 - 240v. So it really shouldn't be a problem for you, but just double check it before you buy one.
For example, an AC adapter like this: AC 100 - 240v Input → DC 5V 2A Output. Then you just plug whatever Qi charger you have into it.
