Yes, all of our FlashRouters include a 100v-240v 50-60Hz power supply. This makes the router compatible worldwide. You can see this under the Specifications tab on any router.
However, they do require an adapter plug for your region to switch from a US plug. We offer these for $5 if you need one.
The only exception to this is the Netgear R8500 which normally ships with a US only power supply. We offer an international power supply for this model here. This add-on is a must for anyone who wishes to travel with this top of the line Netgear router.
