We had pretty much deduced this by doing the math, but here are the "official" numbers of hours to fully recharge a Roadster as seen in the 2008 Roadster owners manual:
Charge Time / Connection
4 hours - 240V@70A <== Tesla Home Charger
5 hours - 240V@60A
6 hours - 240V@48A
7 hours - 240V@40A
10 hours - 240V@32A <== old RAV4EV/RangerEV "Level II" standard
15 hours - 240V@24A
18 hours - 240V@16A
20 hours - 240V@12A
40 hours - 120V@12A <== Common household outlet
Interestingly they say you can define different current limits for different locations and it uses the cars GPS to determine if you are parked at a particular charger that you want to have set for a particular current limit.
