Equivalent plug question

I recently bought a 3rd Gen Alexa from the UK. Previously, I had a few 2nd Gen's which were powered by micro usb to usb, so I was surprised to find an all in one UK plug for the 3rd gen, which must require more power.

I have taken the plug to a couple of interdiscounts and they were not able to help me.

Can anyone help.. is there an equivalent power supply here in Switzerland... I want to avoid an ugly adapter.

I have attached two pics. In case hard to read, they say 12v - Max 1.25A

Your pictures fail to show the plug that fits into the appliance itself. If it's a fairly standard fitting then there are any number of multi-fitting adaptors available, e.g. https://www.amazon.fr/s?k=Bloc+d'alimentation+universel

Which means your replacement must provide exactly 12 V and at least 1.25A.
For the rest get a caliper and a volt meter to determine diameter and polarity.

Just pass by, have the old adapter along, and they will satisfy your need from stock.

It is called a Europlug https://en.wikipedia.org/wiki/Europlug Fits in Swiss, Italian, French, German and other sockets as uses all around Europe. There are only a few islands and a peninsula where it will not fit.

There are only a few sizes around the size that you want. If you order one of those adaptors from Ace1's link with a choice of plug, you'll almost certainly be okay.

Make sure it can provide 12VDC at at least 1.25A.

You were told wrong. 12V is 12V and the quoted Amperage is the maximum the adaptor can provide, but the device will only draw the current it actually needs, so a higher capacity adaptor will work absolutely fine without any risk. The ones in the link can be set as required, so just check the polarity and make sure you set it accordingly.

One small remark before people get ideas, a adaptor with a higher capacity will indeed work fine, but one should not overdo it, hanging a 5A adaptor on a .5A piece of equipment which normally has its own .5A adaptor brings risks like the wiring simply not capable of handling things when an error occurs. And internal safety's might simply not able to cut down a 10 times higher current properly.

The one from your link can be set, so no problem there. As for the rest, anything a little over will do fine.

I have attached two pics. In case hard to read, they say 12v - Max 1.25A

The plug on the Alexa side is a DC or Coaxial power connector, a standardized plug with few, common sizes. Described with inner and outer diameter, most common 5.5mm outer and 2.1mm_or_2.5mm inner diameter. Just measure it.
https://en.wikipedia.org/wiki/Coaxial_power_connector
Then you just need such a "swiss plug", with output 12V and 1.25A or more as said above. Such as for example here on ricardo:
https://www.ricardo.ch/de/a/netzteil...dc-1046087578/
But I agree, best to take an adapter plug covering all voltages and with interchangeable DC plug sizes.

Total nonsense.

Standard mains supply 10A or more, but plugging in an appliance that consumes 0.01A is no problem.

Yes it will work, nobody doubts that.

Thing is that the cables and internals of the appliance should be capable to withstand the maximum the power supply can deliver in case of an error. And if you don't agree you might as well remove the fusebox from your car and make it all direct connections.

As the voltage increased the cables required will be thinner, 240v @10amps requires the same cables as 120v @20 amps.

So when you build a PC, you should make sure your Power supply is near enough exactly what you need to power the PC and components and not have any spare capacity?

Really?

Perhaps you need a little re-think otherwise I've been doing it wrong all these years...

Right, so the little 5w power dongle that you plug into the mains to charge your phone should be able to handle 2300W?

Wrong.

Wrong.

240V @ 10A requires the same size as 120V @ 10A.

240V @ 10A requites cables half the square area as 120V @ 20A, though both provide 2400VA of power.

It was a remark in general and not specific for this situation only.

With the 5W power dongle the thinner cable is after the Dongle so you would need a double error to overload the cable.

(Not to mention that it would be smart to actually have a small fuse upfront, it will save some houses from burning down due to phone chargers catching fire)

You have not payed proper attention in class

Voltage sets the minimum requirement for isolation, Amps set the minimum requirement for thickness of the core of a wire.
