For those who might be interested, Amazon has just started selling yet another 16a L2 EVSE, this one made by EVmiles. It features a 14-30 plug and a 17' cable. The seller states it works not only on 240v(L2) but also 120v(L1) of course with a plug adapter and since this EVSE can draw up to 16a you'd need a 20a circuit. 12 month warranty and comes with a zippered carrying case and probably not UL listed like most of these Chinese EVSEs. I have a similar Ebusbar I've been using trouble-free for some time, this one looks quite similar. In fact in this listing the seller states if you want a EVSE with a 10-30 end to order the Ebusbar so I'd guess they were basically the same. My only real beef with my Ebusbar is the end cap which broke off after only a few uses, you can still use it but its no longer tethered to the plug and this EVmiles looks to have the same crappy cover design.
