I charge my i3 at home right now and it's feasible. European AC plugs have 220V and can supply up to 16A before melting the socket. That is 3.5kwh charging. 33kwh battery in i3 can be charged in around 10 hours from zero which provides around 200km (~130 miles) of comfortable driving. More if you go for economy.

Tealas have much larger batteries though.
