When I travel to France or Italy, I just take a plug converter and an wxtension cord that acts as a cube tap. Everything plugs into that. Look at the fine print on your chargers, they probably work fine on 220V / 50Hz.
More important than power adapters are these tips if you have not already considered them.
1. Medical evacuation insurance (a good policy).
2. Carry cash under your clothes, not to be spent $1,000 in flat new $100 bills. Credit cards do you know good in an emergency.
3. Travel light. If you luggage won’t fit on the seat next to you in a cab, you have over packed.
4. Register with the U.S. consulate to let them know what day you will arrive and depart. Check travel warnings.
Here, this is similar to what I have in my laptop bag:

Mori Luggage at the mall used to carry them, if you need it ASAP.
They have 230v but the average 220 v European round-pin plug, with or without the grounding prong, seems to work fine. So buy an adapter with that configuration for your US plugs. But just look it up online (Czech republic plugs).
However, the problem is that there are generally very few outlets.
Buy a 4 or 6 USB port device that you can plug into you European adapter plug. You can get it from amazon.
Or buy a bunch of European USB plugs. Or ask at the front desk to borrow whatever you need. Usually they do that.
For what it’s worth, I visited the Philippines four months ago. Although the Philippines were once a US colony (from 1898 to 1946), I still had to use an adapter; they have the same level of current as Japan and Australia.
You may already know this, but many places won’t take American Express.
Not sure about the Czech republic, but from having traveled to other countries, I’ve always told folks to take washcloths.
Leave all that crap home......That's what you would have done 20 years ago since you never had it..........
Experience foreign travel for what it is, not a technological accessory.................Sheesh!
However,I've never been to Eastern Europe so....
Give us a report on the Pilsner Urquell brewery, Budvar/Budweiser and other breweries.
Let us know how it goes. I’m considering a similar journey.
Beware in Prague for the Money exchange machines they are a rip-off. Other than that enjoy, you’ll love it there.
For your electronics, you will probably just need a converter plug (round to flat) Check the transformers on the chargers, but generally anything from cell phone through laptop will convert anything from 110 through 240.
For other electrics, you’ll need an converter as well as the adapter plug. Be sure to get a heavy duty model if you are going to take something high wattage like a hair dryer.
I don’t know about the Czech Republic, but in Germany the outlets are round and recessed, so depending on the design of the converter, you sometimes have to pair it with an adapter plug to fit into the outlet. The weight of the converter tends then to pull the adapter out of the socket. A roll of electrical tape can help in those situations. You shouldn’t have that problem with the chargers that just use an adapter plug.
Lay out all the clothes you think you will need and then lay out all the money.
Now take a quarter of the clothes and four times the money. :)
In all seriousness do keep a copy of your passport and other id on you but not with your original travel papers at all times. It makes it much easier if the original is lost or stolen. Which does happen occasionally and even once will ruin your day.
Have fun!
Take junky underwear and throw the used pair away each day. You were going to throw them away anyway, so take them instead.
You’ll need the extra room in your bag later!
Being a person who, you might say, has been around the block a bit, here are some items that I really like -
https://www.amazon.com/Anker-PowerCore-Ultra-Portable-VoltageBoost-Technology/dp/B00Z9QVE4Q
https://www.amazon.com/Anker-Charger-PowerPort-iPhone-Galaxy/dp/B00P936188
https://www.amazon.com/Anker-SoundCore-Playtime-Bluetooth-Portable/dp/B016XTADG2
Anker is basically bullet-proof, so just use them and not worry. I believe that all their products can handle 120/240. It’s easy to find plug-adapters on the web, just search ‘Czech Plug’
Obviously be sure to buy a good number of cords, and of the right type.
The battery liberates you from having to find ‘charging ports’ for at least a full day, and one that size is usually enough for 2 people for a full day.
The speaker is optional, and there are smaller ones, it just depends on how much you want to carry, but Bluetooth speakers are great, compared to what you typically get in a phone or similar device.
The power brick that I show is their larger one, it will basically run/charge everything you have, and all at the same time [other than most laptops]. They do have a smaller one with 4 outputs, which is what I typically travel with, since it’s lighter. But be sure to have an extension cord, if needed for the brick. If you do have a basic, single-output, brick, it’s not a bad idea to bring that too, as a backup.
Also watch out for grounding and polarization [one prong bigger than the other] on US cords. It’s overkill in our great society due to fire chiefs having too much political influence [that’s for another thread], and can keep adapters from otherwise working. In my case, I grind-off the polarization and also cut off the stub on extension cords that prevents the use of a 3-prong plug with a 2-prong extension cord [try plugging one in and you’ll see]...so far, I’ve survived.
Have fun and enjoy the really cheap prices there as well as being away from the ‘social experiments’ going on to the west of that country!
Most hotels do include WiFi! I invested in a 220v plug with 2 USB ports on it. It’s better than having a 110 adapter plug and then plugging a US USB adapter into it
Now that you have good answers...
A scientific study of interest to travellers:
“According to a new study published in the Journal of Psychopharmacology, it’s not all in our heads—alcohol really does improve our foreign language skills.”
