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

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

This is the quality content I expect from EEV. Bravo 👏👏👏

Just imagine entering the parking lot and seeing Dave summoning the energy of the portal of power surrounded by 283 power adapters

I'm sure according to draconian Australian electrician licensing rules, this qualifies to be the crime of the century.

Finally! I can't tell you how many sleepless nights this problem has been giving me. I'm glad Dave finally tackled this vexing problem.

Sagan is a young man now! Damn! It feels like it was yesterday when he was but a wee lad! :D

Edit: lol, a quarter of a century, not of a decade!

Of course, when powering a heater, the warmth from each adaptor was still heating the room so was technically not "lost". You were just drawing less power as a result. Many of our UK adaptors are fitted with 13 Amp fuses which would get quite warm on a 2kW load, so I expect the voltage drop here would be somewhat higher.

Arlec makes a few different types of double adapter - ones that go to the left, right and a vertical one. I assume using flexible wiring inside allows them to use the same wiring for all variants instead of having a bunch of different types of stamped brass.

Looking at the thermal camera it seems like there might be two different versions It would be interesting to take apart a "hot" one and a "cool" one to see if there was any noticeable difference in construction. Perhaps a thicker gauge wire. It would also suggest that some adapters has a higher loss.

That was a pleasant video, thanks also to Sagan for all the hard work!

From the manufacturing quality inside they look quite decent, and the fact that in AU there are blades for all of the connectors make up for a good connection.
In germany, with those Schuko system, especially the PE connection in a cascade can get to very high values, so that effectively in case of a problem the minimum short circuit current is not reached so a fuse has to blow the slow way.

I´ve been in Shenzhen at this huge electronic market (several high towers linked together on a dozen floors), and the people sitting in the boots and talking with customers use the idle time for assembling wires and stuff - most probably also those ones. They´ll have a bunch of the contacts and cables, and they will be crimping them when there is no customer around.

It was probably manufactured by a small team in china rather than a large company. They wouldn't bother getting custom tooling for shaped brass inserts. Easier to just buy off the shelf terminals and wire. A small company only making double adaptors because they found a box of 10, 000 surplus terminals or adaptor housings for surplus pricing at the Shenzhen markets. There's lots of money to be made in china assembling stuff out of whatever surplus parts are easy to get at the time,

**walks down to car park after a long day of work**
**sees man rolling around on the ground, talking to himself, with hundreds of power adapters plugged into each other**

[patrolmaverick]

That's mind blowing. Like who even has that many double adaptors for a start, let alone why is there that many of them sitting in a bin if they're all functional.
And how do you just happen to find that many sitting in a bin?
That's got to be one of the most absurd things I've watched, and I love it.

[knarf]

just so you know, that rolling away backwards on a mover is gonna definitely be used a lot in future edits by people, no way it wouldn't, great stuff and with Sagan too! I was indeed, entertained!

[Sonnell]

I truly appreciate how much fun you had with simple adapters. Never let the inner child of you grow old :)

[grahamprice]

This was awesome, would like to see an extension cord test, Dangers of high current while its coiled up etc.

9:54 "No idea why I wrote mW, it's obviously milli-ohms" -- OBVIOUSLY Dave's Greek fluency led him to accidentally write the omega symbol in lower-case.

[brettski]

The parasitic capacitance could serve as power factor correction for the inductive load of the motor in that heater.
