Re: Duosida EVSE Just Arrived.

I know that your company sells a portable EVSE that automatically adjusts the current to match the supply; however, I can't afford a $900 US EVSE. The OP stated early on that he can't afford a $900 EVSE either. So, we make do with what we've got.

I have zero concerns using my adapter cable for the purpose for which it is intended - exclusively for my portable EVSE, which allows me to set the amperage rate before I plug it in.


How about a $900 unit for half price? We have used ones.

We also sell a direct competitor to the 16 amp Duosida, built for us by the same company that built the Duosida. Ours has several changes, but the best change is interchangeable plugs (much like our $900 unit) for:

NEMA 14-50 (RV parks)
NEMA 10-30 (old dryers)
NEMA 5-15 (household 120 volt outlet)

We can even modify the 14-50 to be used with 14-30 (new dryers) and 14-20 (stoves).

But, folks who swap around amperage plugs the other way, well I've said what I think about it. You could NEVER overload a circuit with our adaptors. We just won't build them that way. We won't suggest others do, either. The danger is too great.

I've seen the leftovers from electrical hack jobs. I've also seen some of the hack jobs before they burn the place down. The only thing different between the two is the fire.

I'm just about ready to order one of these. Been quoted $188 for one with a 10-30p plug and 10-meter cord shipped via air freight.

Question is, how would I convert the plug to 5-15 120-volt? Wouldn't use it very often but would be nice to have the flexibility.
Would I buy a different input cable? A plug adapter? Any sources y'all would recommend?

Personally I would have not gone with a 10-30p, even if your outlet is a 10-30r, unless it's all you ever plan to use. Reason being, 10-30r(female version plug) is basically impossible to find. Purchasing an outlet and box is really your only choice which is bulky, costs more and isn't probably waterproof for outdoor use. Instead I would have suggested a L6-30p or L14-30p, both of which the female variety are easily found and at places like Amazon cost <$10.
In your case, unless you want to cut off your 10-30p end and wire on something like a L6-30p, your only real choice for 120v use is to purchase a 10-30p wall outlet(you may be able to find one with a built in outlet box, usually brown in color and Bakelite plastic) and wire it with a 1' piece of 10-3 wiring to a 5-15p(standard wall plug). Running the 10-30s neutral to the 5-15's ground, and one of the 10-30s hots to the 5-15 hot and the other 10-30's hot to the remaining 5-15's neutral connection. Like I said it won't really be waterproof and the 10-30r isn't really meant for outdoor use, but it would work, albeit it bulky and maybe a bit hokey looking.

If you won't want to make one yourself you might try VegasBrad on MNL, he may sell or could custom make such adapters, I believe for ~$30 + shipping, although the price could be higher, I'm just going off memory.

10M cord, whoa thats a long one! explains the slightly higher price for your EVSE, still IMO it can't really be too long, especially if you plan on using your EVSE in a variety of places. I got a 8M and have used every bit of it on a couple occasions, safer to extend the J1772 cable than the input cable.

I think you're right. How about an EVSE with a 6-20 plug instead, along with a 6-20R to 10-30P adapter?

Here's an example adapter:

Then for plugging into 120-volt, an adapter like this:

Would this setup work better?

Yes I wasn't sure what Duosida you were looking at but if your only looking at a 16a it should be fine to go with a 6-20 plug. Note I'm not particularly excited about the adapter you listed from Amazon, it says it's only 14 gauge, it should really be 12 gauge for 16a continuous use, I mean why they would save only pennies and skimp on 14 gauge wire is beyond me :?
I like the L6-30 plug as I prefer it's larger lugs and plugs, plus most of my EVSEs are 30a but again if you plan on mainly using 16a EVSEs and plugs, it should be fine. You'll probably have to make your 10-30p to 6-20r adapter as thats probably not a very common conversion to make. A 10-30p plug on one end, a length of 12 gauge 3 conductor wire and finally a female 6-20r plug for the other end. I suppose for 16a use the 6-20r is even more compact and lighter not to mention cheaper than the L6 locking plugs.
