I got mine with 12, 16, 24 and 32 amps so as to correspond to 80% of 15, 20, 30 and 40 amp circuits.
I'd like to make a two 120V legs to one 240V circuit set of cords too.
You could also purchase something like this:

Which along with this, would do what you want:

Amazon also sells this similar adapter:

I just made mine with these parts and a 1' piece of 12-3 wire:

I have at least a dozen different adapters to go from most L6 and L14 plugs plus others. I just charged yesterday on the fly from a friends L14-20 outlet by combining 3 different outlet adapters, worked great. At first I was charging at 19a but after checking things after ~20 minutes things seemed a bit warm. I then dialed my Zencar down to 13a and everything cooled down after a bit. In this case it would have been handy to have your 16a setting, which would have probably worked just fine. The way it was I ended up charging for almost 4hrs and my Leaf was 100% charged by the time I left anyway. At only 120v it would have been lucky to get to 70 or maybe 80% which would have been a bit close making it home.
My old Juicebox is the nicest as I can adjust the current in 1a increments from 6a all the way to 40a, unfortunately, it's so bulky and heavy I really prefer to use my Zencar on the road and my Juicebox in the garage.
