Zimní dovolená u moře: jaký adaptér nebo powerbanku sbalit, ať nezůstaneš bez šťávy?

Winter vacation by the sea: what adapter or power bank to pack so you don't run out of juice?

Are you tired of watching your friends post exotic photos on Instagram while you sit at home in warm socks? Then go for the warmth too! But before that, read what power bank to take with you so that they let you on the plane. And also what travel adapter to choose if you're heading to a country with a different type of socket.

We have a solution for you, whether you're heading for a winter adventure to Egypt, Thailand, Greece, Zanzibar or any other popular destination.

A universal travel adapter will prevent unpleasant surprises

That a socket is just a socket? Unfortunately not. If you're not prepared, you may be surprised by the inconvenience of a different type of socket than the one we use in the Czech Republic upon arrival at your dream destination.

There is usually no problem with the voltage, but the main difference is in the shape of the socket (or rather, the shape of the sockets).

Fortunately, there's a solution: pack a universal travel adapter for your winter vacation by the sea , such as the FIXED Voyager 120W , which fits into sockets all over the world and also functions as a charger for your devices.

This way, you don't have to buy a special adapter for each country, but you'll have one "swiss army knife" that you can use everywhere. We recommend choosing an adapter with USB/USB-C outputs, so you can charge your phone, watch, or headphones from one place.

Where can you find which types of sockets?

In Europe, the most commonly used sockets are type C and F (including the Czech Republic). In contrast, type G is used in England or Zanzibar , and type D/M is common in parts of Asia and Africa . In countries like Egypt or Thailand , you may encounter multiple types of sockets, so the safest choice is a universal adapter that will ensure trouble-free charging regardless of your destination.

And one more important tip: If you're flying, always put your travel adapter in your carry-on luggage , not in your checked luggage.

This way you will be able to charge your phone even if your checked baggage arrives at your destination late.

Which power bank can be taken on a plane or the rules in 2026

There's nothing worse than your phone dying on a long journey to get warm and you don't have any power source nearby. How do you find your accommodation address after arriving without your phone?

Therefore, be sure to pack a power bank with you for peace of mind. But be careful, if you are flying by plane, there are some restrictions. Not every power bank will pass through airport security.

What rules apply to power banks on airplanes in 2026?

  • The power bank should always be in your carry-on luggage , never in your checked luggage. This rule was introduced by airlines for safety reasons to minimize the risk of the power bank unexpectedly catching fire or exploding.
  • In the vast majority of cases, you can travel by plane with power banks that have a capacity of approximately 27,000 mAh and an output of up to 100 Wh . Don't worry, most power banks meet these parameters, most often they have a capacity of 10,000–20,000 mAh.

For example, airlines Smartwings and Ryanair allow power banks up to the aforementioned 100 Wh (≈ 27,000 mAh). Higher capacities require special approval.

  • With large "bricks" that can power a laptop all day, there may be a problem. For example, with a power bank with a capacity of 30,000 mAh , airport security or the airline will not let you on board in 90% of cases. The reason is again security.

Do you need a power bank that will keep you going (and not only) during your winter vacation and at the same time let you on the plane without any problems? Check out the FIXED MagZen 10 Crystal with wireless charging and MagSafe support. Thanks to integrated magnets, the FIXED MagZen 10 Crystal automatically attaches to your phone. It charges your phone and other devices quickly and quietly several times in a row.

Before traveling, we recommend checking your airline's website to see what their rules are regarding power banks. For example, some airlines do not allow the use of power banks during flights.

How to protect your phone? For example, with a waterproof mobile phone case

Great, charging is now solved, whether you're on the road or enjoying a winter vacation by the sea.

But if you're going to the beach, in addition to a power bank and a universal travel adapter, it's worth packing a few sunglasses. accessories that will ensure that your mobile phone or other electronics remain safe and unharmed.

  • The absolute essential is a waterproof mobile phone case , which will keep your smartphone safe even if it falls into the water for a moment. For example, the FIXED Float case with a high-quality locking system and IPX8 certification can easily handle immersion to a depth of up to 5 meters. Thanks to the touch foil, you can also control your mobile phone underwater.

By the way, waterproof cases with IPX8 certification are also suitable for holiday diving (up to the aforementioned depth of 5 meters), so you can easily take photos and videos of the beauties of the sea without your phone getting wet.

TIP: Did you know that sand acts like sandpaper on your phone's screen and other parts? It can permanently scratch the phone's glass and ports. That's why we recommend using a waterproof case on the beach during your winter vacation by the sea, even if you're not in the water.

  • If you don't have one yet, don't forget to put a screen protector on your phone . First, it will protect your phone from sand and other debris on the beach, and it will also save you if your smartphone slips out of your hand. If something breaks, make sure it's the screen protector, not the display.

In the FIXED offer you will find many protective tempered glasses, including ultra-resistant ones .

  • In general, it's not a good idea to use your phone without a case , but this is doubly true on vacation, because you'll be flying around with your phone all the time and the risk of it falling to the ground is high.

If you have the new iPhone 17 Pro, you will need the FIXED MagPure hardened back cover with MagSafe support (thanks to integrated magnets, the MagPure case works with all MagSafe accessories).

Enjoy your winter vacation by the sea without worrying about charging or electronics

A vacation should be about relaxation and peace of mind, so pack everything you need so you don't ruin your beach experience with unnecessary stress.
