Those "compact" things are just glorified light dimmers . It's been said before .

Right, but manufacturers must state so because i hear a lot of people constantly running into shocks, fires etc. as they are misled. In fact people are being misled because seller wrote in description that this "dimmer" (2nd link) fits DeWalt charger.

What do you think about used charger by the way (3rd link)? Worth the risk? eBay does not offer life insurance yet by the way.

Those things are only good for resitive loads for a minute or two like hair dryers and shavers etc. Your charger is either an inductive or capacitive load, I have one of those things that I bought when visiting the US as a curio and it is not much more than that. You must either get a European charger or a proper transformer or bin the power tool any thing else is asking for grief.

It's a switching supply inside so the 200W only lasts for milliseconds while the Low ESR Caps charge up .

Can you explain please? Is that good or bad in your opinion? I have seen sellers with 92% rating but compared to them, 99% is almost perfect.

The power supply is a simple step down converter, using an output that is connected directly to the rectified mains input. Best is to use an isolating transformer, the site transformers are common enough in Europe on work sites, so these will do the job. Voltage converters will make a lovely smoke generator.

A site transformer is an extra load , he'd better get a used 220V dewalt charger instead .

The site transformer will be more generally useful for any other 120 V items that may also need power. The 220 V DeWalt charger would be more compact, but will be confined to just the one use.
I'm not an EE--what am I doing here?

If you go round the larger building/construction sites you may be able to pick up a site transformer for free or a drink, many of them get condemned by the site safety officer due to the spring loaded socket caps getting knocked and broken nothing wrong with  the transformer but no socket cap and they get slung into the skip.

Certainly yes . Big 'n heavy and he can put a heck more things then just a dewalt charger .
