At the moment, we are shipping AstroBoxes with U.S. plugs only. Sorry for any inconvenience around this!
Here are your options to get around this:
1) Obviously, you could pick up a plug on Amazon or at a local electronics store. Just make sure it is 2A 5V and the end of it has a microUSB plug.
2) Use an Android tablet plug: The AstroBox uses a standard 2A 5V microUSB, which is the same plug that most Android tablets use. So, you can use your Android plug if you wish to (or buy one at a local electronics store).
3) Use a phone charger plug: Most phone charger plugs are 1A 5V. We use these all the time around the office. The only difference between using a 1A plug and a 2A plug is that your wifi range will be much lower with the 1A plug. If your AstroBox is going to be near your router, this is no problem at all. Also, if you intend to use the AstroBox's hotspot, you'll need to be in the same room if you use a 1A power supply.
In the future we will ship with more plug variations, but for now we can only do U.S. plugs.
Thanks! And happy printing!
