I've been trying to find an EVSE with the J1772 that had options to adjust the current from as low as 6A (the standard minimum) all the way up to 12A in a portable design to keep with the Leaf. The one that comes with my current EV is just way too big (basically a portable L2) from Nissan and while it's cool to have something like that, I was really doing fine with the L1 for backup purposes before. So, since my old L1 went with my old 2013 Leaf, I've been shopping around for a replacement.
Anyway, I found a site (in China of course) that sells all the parts needed to build one quickly (mainly just wiring up, no soldering needed, board is all programmed) and with some easy to print templates, make a simple L1 EVSE that works on 120V AC (or 240V AC technically also supported, single phase) with a simple button that changes the charging current from 6A, 8A, 10A, etc with the simple push of a button, also works on the fly while charging. It also remembers the settings when you unplug and use again later.
Why have a L1 that can be set so low? It is handy when charging from Solar or any outlet where you want to share power and not trip a breaker all the time. The one I wired up also can go as high as 16A (on 120V? yeah, not a great idea, but it supports it!). So anyway, all the time and parts it took to make it, only cost me about $200. Maybe not the cheapest one you can buy, but certainly very flexible for power settings, which is real handy for me to have.
Picture below, all generic looking I know, but it is functional and useful! I think I did a good job on the front part where the text is to show the current levels, power light, fault light, etc.
