Yes, if your dryer outlet is a NEMA 14-50 or 14-30 (it might be something else). Here's an image of receptacle types:Mauileaf wrote:The 14-50 to L6-20 adapter is all I need after an upgrade?

Technical stuff: The adapter works with both 14-50 and 14-30 because the neutral pin is cut off the plug. The L6-20 end needs only three wires: Hot, Hot, Ground. Neutral is used for dryers and stoves so that they can have 120V clocks and controllers. It is not used for a 240V EVSE.
Also, as planet4ever said above, it is crucial that the outlet you use for charging the LEAF be the only one on the circuit. Is it?
I like having a meter to track my electricity usage from the wall so I can track the exact cost of fueling my car. But I assume that you probably wouldn't want to install something like that in a rental house. If you do, DaveinOlyWA explains how here: Refurbished utility meter installationI would get a separate meter for fun?
I have two portable EVSE units. The one modified for 240V lives in my garage except in the rare instances I need to use a 240V plug to charge down in town. The 120 V one lives in my car since I live in a remote area with no public charge stations whatsoever; it is my emergency backup. But Nissan raised the price of their portable Panasonic unit so buying a second EVSE is now quite expensive. If you can get by without carrying one in the car I'd just leave it in the garage.
