Yes versatility is what sold me on doing the EVSEupgrade but I was lucky enough to be able to have mine upgraded to 20a as I have a '13, to me the extra 4a was really needed at times. It's a little bit unnerving having to push a paperclip inside the end of a live j1772 end so I generally unplug it first, then install the paperclip and finally plug it back in to make adjustments. Other than that it's a breeze to change the maximum output current.gregn said:jjeff said:While the EVSEupgrade will be better than nothing, actually more than twice as fast as your OEM EVSE, you still won't be getting the maximum benefit from your work 30a outlet, only about half (16a). Now if you had a pre '15 OEM Leaf EVSE you'd get closer as those could be upgraded to 20a. In your case a 24a EVSE would gain you the fastest recovery time for your 27a Leaf. Of course if 16a gives you more than enough charge thats OK too, just thought I'd point this out
Lastly do you know the NEMA type of outlet you have at work? EVSEupgrade uses a L6-30 but I believe they sell adapters($25 each) that allow you to plug into various other outlets. You can also make your own adapter if your technical but often times the cost of the parts might approach the $25, if they sell adapters to the outlet you have.
That speed increase is fine for what I need. I like the fact that it is a versatile unit. 120 or 240 V. Yes I bought the adapter.
Not sure of your commute distance but at 15 degrees and snowing I'd be pressed to do 60 miles on my full bar '13, I generally need to charge at least 1hr at 19a L2 halfway to make that trip, warmer temps it's just fine without a supplemental charge and in the summer I can even make it with a 80% starting charge. Cold and even snow kills range
