Oh yeah I'm sure this hasn't been stamped by the Underwriters Laboratories.https://www.ebay.com/itm/274944491474
I'm guessing you plug into a free charger somewhere so that you can run your household appliances for free?
There is a darn good reason someone made these and needs these, but other than abusing free charging for free electricity, I don't know what it could be.
BTW putting "240v only" on those plugs with a label maker doesn't indemnify you from legal action.

I believe that this is similar to EV doubler. Lets you charge a bit faster using 2 outlets .

I don't understand how the sellers can sleep at night.

I built something similar, except I put an L6-20R on the receptacle end. I put dual duplex outlets along both walls of my garage. Separate circuits, on different phases. I use my "doubler" if I need to charge a second EV in my driveway...at 16A.

How would this make anything free? It has female receptacles, what plugs into what?
It's the perfect phone charging dongle.

You plug an EVSE (EV charger) into one end, and it powers the two receptacles.

I have a similar adapter, but it goes from J-1772 to NEMA 14-50R. I use it mainly for plugging other EVSEs into my EVSE in the driveway for testing purposes. It works great for that purpose!
It'll be fun to see a diesel powered RV blocking 6 Tesla stalls with Magic Docks while it powers the entertainment center for an evening.
It has to be safe. Look at the label warning 鈿 electrocution.

That's great, if you don't mind two 5-15Rs with 240V on each of them.
I've seen people wire up transformers to actually bring the voltage down to 120V. It's like someone has the idea they'd split the phases back out but didn't realize J1772 only provides two hots and no neutral.

Extra voltage never hurt anybody. #fact

Back when I was driving my homebuilt 鈥88 Civic EV conversion I fitted it with a J-1772 port. In addition to powering the on-board 5KW charger it also fed a 6-15R outlet for a 1500-Watt step-down transformer to 120 VAC. The transformer was used to supply power to a timer controlled under-dash heater to preheat/defrost the car in winter. I have been almost expecting to see someone with a van camper fitting it up with a similar system to swipe electricity from free charging stations. The circuitry required to signal the charging station to activate is quite minor. There at least used to be a company that offered a J-1772 to 14-50R adapter, though there was no neutral. This did allow EV conversions to access 240 VAC from public J-1772s without modifying the EV.
I telephoned into my local Electric company to get more details about their programs for solar and/or EV charging.

At the end of the call, I made a joke by saying: "And my best accessory, is the extension cord I put underground to my neighbor's power outlet!"

She responded with: "Oh, we always catch those!"

I guess it happens often!

The Quick 220 System does the same thing, but is full fused and certified for consumer use with one model going up to 20 amps @ 240v (which I guess should only be used up to 16amps like yours).

No, according to his description on eBay, it is for other "electric" vehicles/scooters who need to charge on the fly, whether paid or for free:

Great for people on the go or living the vanlife van life RV and beyond.

Electric Vehicle (EV) EVSE Charger J1772 Adapter to Onewheel or Scooter or any device that can accept 240V
Many devices such as phones, laptops, electric bicycles, scooters, efoils and electric unicycles (EUC), Electric skateboards (esk8 or e-skate) have power supplies that are designed to work with worldwide voltages so be sure you check your device accepts 240V before plugging into this 240V adapter.
Was wondering if anybody was going to read the link before getting "outraged" at this potential for "abuse".
It's a great idea for "van life" power needs in the middle of nowhere but with EV charging capabilities.

I've been watching some YouTube videos and fantasizing going on the road!
Oh, man... I'm going to keep an aha out on freecycle for an ugly, old electric range. I'll put it on my little trailer and take it to a public L2 site and sit there making fajitas.

EDIT: I think I found it...

Seriously, though... if you have free L2 in your area, you could go and plug in one of these adapters to charge up some deep cycle batteries, and then go home and run your house on them. I mean, yeah... It'll cost you $10,000 in batteries and a big inverter...

EDIT: Or dry your laundry! The the ideas just keep coming!
