For some toasters that's fine, for many not. You can always drop the electronics & elements separately, but it gets more work.
FWIW the cheapest way to do 260uF NP is 2x lytics back to back with a diode on each so neither sees more negative than -1v.

Your 4541 needs to not just measure time but voltage too so it compensates. I wouldn't be too surprised if that's a doable mod. If you had nothing more useful to do.

Won?t really work, as others have said. My wife burn?t her favorite hair dryer out by forgetting to turn the swith from 115 to 230 on a trip some years ago. Solution was to buy a local (European) hair dryer.
I wouldn?t think that toasters are so expensive (even in Europe) as to be worth buying a big transformer.

That would cause a huge unbalanced current in the source transformer.
There are optical triacs that activate on zero crossings. Set one to give a
50% duty cycle. The toaster element won't care, but the RC timing circuit might. That doesn't matter. The potentiometer is not very accurate anyway, and it drits badly.I simply set the toaster pot to maximum and use a separate digital timer to adjust the browning. I have three settings: 2:15, 2:30 and 2:45 min:sec, depending on the type of bread, thickness, and length of the slice. The nice thing is if I somehow forget to set the timer, the toaster timer will expire before it sets fire to the toast. (BTDT)
I don't know if that would still work with a 50% duty cycle AC, but it's worth a try. Maybe the AC rectifier in the toaster would have to be modified. The circuit is very simple and easily traced. Do the needful. (Indian phrase. Useful at times.)

Check Amazon US. You can get 220V appliances real cheap. Have them ship to your hotel. Here's some toasters:
flying toast!
oh, you mean the transformer. how many watts of cooling are needed?
I don't like a 120V bite at all (probably really bad for me, too) and have very dry skin in the Winter, too. I'll shut the power off before working on electricity, thanks. It's not very hard to walk over to the wall and flip the switch. ;-) I've also gotten bit when I separated a neutral and there was something else on the line back-feeding power in the neutral.

Kitchen Aid products are half price. Over the last 2 years I have saved mor e than 1000 USD, compare that to the cost of a transformer of 70 USD?

By the way, it's only certain brands
Kitchen Aid Festool tools
Whereas for example Garmin products are sometimes more expensive in the US even though the exchange rate US-DK has fallen by 15% the last year

So then buy a transformer. What's your problem?
After saving that much, there shouldn't be that many Kitchen Aid products left. A toaster is a pretty small investment. Why spend $70 for a transformer to power a $19 toaster?
A 1kW toaster on 120V has circa 14 ohms resustabce when hot. On 230V, with 50% duty cycle, that will dissipate circa 1900 watts.
The solution lies elsewhere...

A 1500 watt 240:120 transformer for 70 USD? I?ve seen lots of ?Converters? for small dollars, but they are unlikely to be real transformers (that is, made of iron and copper). One way to tell is to look at the shipping weight.
I?d believe $140, though:
. Rockler is a well-respected seller of woodworking equipment and supplies in the US, and I?ve bough many things from them.

A toaster worth the loaf of bread costs a lot more than $19.
Have a kitchen full of KitchenAid appliances.
...and a basement full of those. ;-)
Are they even more expensive than they are here?
None of those.
Like. Solenoids operate so briefly they probably wouldn't mind. A series cap would be doable anyway.

Double voltage quadruples power, diode only halves it And the electronics wouldn't work, usually powered by a capacitor dropper.
