A:Answer The question is about the input voltage not the output voltage. Electronics in the N America takes 110/120V, Europe and elsewhere 220/240V. Some electronics like laptop adapters and mobile charges can automatically take 110-240V without a step-up or step-down transformer, to be able to work anywhere in the world.
Now, I am not sure whether this router takes 110-240V or not but I have other Linksys routers that support 110-220V
