Searching Amazon I came upon another Chinese made EVSE, this one is portable and is adjustable to 10a, 16a and maxes out at 32a.
While the company site does mention UL listing, I believe it's more talking about the J1772 connector and not the overall unit.
It looks like it uses a NEMA 10-50 outlet and Amazon description does say 220-240v although I do have a question into the seller to see if indeed it works on 120v or at least 208v.
Only 3 in 1 portable charger on the market, 10amp , 16amp, 32amp, you select amps
1 year warranty
18.5 feet in length
Easy to read LCD display
FAST CHARGING - 7.7kW of power to charge your vehicle quick
At $555.99 shipped I think I'd probably go with something like a Juicebox if I wanted higher charging capacity than my existing portable EVSEs but it does give one another option for those wanting full charging in a portable EVSE on newer Leafs.https://www.amazon.com/Premium-portable ... ev+chargerhttp://khons.en.alibaba.com/
Oh it looks like the company also sells several J1772 extension cords and such, not sure who sells them though.
