I'm really sorry if I'm asking a silly question or the Home Improvement is a wrong place for that but it's better safe than sorry.

I'm going to buy a couple of electronic devices from Amazon, which was made for US market only (charging station for game console accessories to be more precise). Since I live in Russia the apparent problem is what this devices' "native" plug will not fit sockets in my apartment. I'm not any experienced in such kind of situation so I tried to google to learn if this issue can be addressed at all. Many forums suggest that I can just replace original plugs or buy a plug adapter, but these devices are not cheap and I don't want to kill them and waste extra money. Both devices have Type-A plug which looks as follows:

  2. plug two enter image description here

  • A lot of these sorts of transformers are 110 or 220 volts. You need to get clarification on what the input voltage can be. If they can do 220v, then the simplest thing to do is get an adaptor.

  • What does the writing say on the adapters? Everything matters there. They have a UL or ETL insignia on them, so they'd be alright IF they accept 240V.

  • Also, are those little wall-warts the "expensive" things? Or does the expensive thing use them for power? Because those look like cheap commodity wall warts made by the billions. Any generic wall wart will do if it has the specs on the low voltage side.

  • @Harper-ReinstateMonica, these are just plugs of the expensive things. Unfortunately the specs are unknown, official support is not very responsive (and probably this question is out of their responsibility)

  • The specs are written on the wall-wart itself. Do you see the writing?

You need to learn to tell the difference between a plain plug and a power supply with a built-in plug (known as a wall-wart).

There are several giveaways that indicate something is a wall-wart and not a regular plug.

  • Wall warts are typically much larger than regular plugs.
  • The output cable of of a wall-wart will typically be thinner and more lightly insulated than a mains cable.
  • The output connectors of a wall-wart will typically be of types that are only safe for use at low voltages.
  • A wall-wart will typically have a label indicating input voltage range, output voltage, power requirements and safety approvals.

Not every wall wart will have all these indications, but most will have at least one of them.

Both of the items in your pictures are wall-warts, if you remove a wall-wart and replace it with a regular plug you will almost certainly destroy the equipment and create a serious electric shock hazard.

Russia apparently uses 220V, which is similar to most of Europe (the EU is nominally 230V but with a pretty wide tolerance band) and much higher than used in the USA. Before connecting a device with a US plug to Russian mains you need to check it is suitable for the higher voltage.

Some devices, especially older ones, may need to be reconfigured for different voltages either by moving a switch, turning an insert, moving fuses inside the device or a variety of other mechanisms. This is unlikely to be the case with wall-warts though.

The label on your wall-warts should indicate the acceptable range of input voltages, most but not all modern wall-warts will be designed with a wide input voltage range (e.g. 100-240V) that covers essentially all mains voltages in the world. If your wall-warts have a suitable input voltage range you can use them with a plug adapter, otherwise you will need to source replacement power supplies.

Unfortunately sourcing replacement power supplies can be a pain. There are a wide variety of combinations of voltage, current, output connector and sometimes even output polarity out there.

More important is the voltage you have in your outlets. I am unfamiliar with Russian power distribution but assuming it is like most other countries outside of North America, it is likely 230V (nominal) line to neutral. The devices that you show are for connecting to 120V systems in North America. So unless you buy an adaptor, you might fry your power supplies the first time you plug them in. It would likely be less expensive for you to search for 230V versions of your devices, they will likely have the right plugs as well.
