EEVblog 1526 - I put 283 Double Adapters in Series with a 2kW Load

[EEVblog]

I found 283 mains double adpters in the dumpster. What happens if you put them all in series with a 2kW load? I'm glad you asked!

[Brumby]

All those double adapters - and you still only used a single appliance.   

I'd be wanting to try it with TWO of those 2kW fan heaters.

You really are a verrrrrrry strange man at times 🤣🤦‍♂️🤦‍♂️🤦‍♂️

This is the most contrived, awkward, forced video ever.

Imagine having fun. How dare you?!

Those double adapters are banned over here (reason: too much mechanical stress for the wall socket). But I'm looking forward to the EEVblog meditation channel promoting Ohm's law.

So that lot dropped 40V.  Dave's only got to scavenge another 1400 or so, and put a shorting plug in the last one, and he can use them for distributed electric heating!

While we are on the subject of things sane people don't stack in series, lets hope his next find is a dumpster full of 9V batteries . . .

I was kind of waiting for Sagan to show up and tell his dad to start behaving normal... or that he is hungry or so...

I would have bet real money that with that IR camera you would have found a couple that were really hot due to poor assembly. Since you didn't I guess the company has good control over the assembly procedures.

Very nice and funny video, Dave.

In the South-East of France we have a sectarian religion called Aumism.
All followers sing 'Aum' (also written 'OM' and pronounced 'Ohm') all day long.



It looks like they now have a new follower^^.

Guru Gilbert Bourdin (sacred name 'Hamsah Manara') fortunately passed away in 1998.
He and all his followers were really weird people.

I would hope its an automated crimping machine, with wires stripped via an electric controlled stripper.
But yeah could also do a high current test as part of QC.

Yeah I expected one to be really bad maybe.

Am I "cancelled"?

[SiliconWizard]

Dang. Takes little these days to get canceled.

As to the adapters, even if it was mostly all done for fun, I'm actually surprised that the long chain held up this well with relatively modest losses.

[Tepe]

Dang. Takes little these days to get canceled.

Little? My local home improvement store only stocks 97 double adapters and Dave's got 283 of 'em!

What exactly would you have done with them?

[Fungus]

All that copper has to be worth a bit. You should open them all up and snip it out... tell us how much you got for it.

[EEVblog]

What exactly would you have done with them?

More to the point, what should I do with them now?
I'm thinking maybe a stargate style ring on the wall in the dungeon? Or even the lab? but there is no wall space for it really.

[SeanB]

Well, you can arrange them to be in blocks of 30, so you can put a double socket outlet on top of each bench, fed from the floor mounted socket outlet.

  but possible.

Donating them to a social store?

[joeqsmith]

You're using a heater for a load.  The adapters give off heat.  Was there really a net loss of overall heat generated? 

If you find enough adapters during the dumpster dives,  you could forget the heater and try using 100% adapters. 

[golden_labels]

If used with a heater, they waste 0% power!

I think you're forgetting a small, but crucial bit of information here. If you had 283 double adapters connected in series, as demonstrated in the video, you would still need a link (or wire) connected between the active/live and neutral pins of the last double adapter to form a complete circuit. Otherwise you will have a 283-double-adapter-long transmission line without a load at the end.

@Ian.M made this point in an earlier post:
