1. What is a suitcase with a USB port?

Title

Suitcases with USB ports have been gaining attention in recent years.

This refers to a carry-on suitcase that has a USB port on the outside, allowing you to charge your smartphone or tablet while on the move. It looks similar to a regular suitcase, but its unique feature is its added convenience .

1. How USB ports work (how they charge)

Title

Suitcases with USB ports have space inside to store a mobile battery , and the battery is connected to the USB port with a cable.
In other words, since the suitcase itself does not have a battery, you will need to bring your own mobile battery to use it.

This system allows you to charge your device while out and about using a cable plugged into your suitcase, without having to search for your bag.

Title

2. How to use the USB port and precautions

Title

It's simple to use, but there are a few things to keep in mind.

  1. Put a mobile battery in the pocket inside your suitcase
  2. Connecting to internal cables
  3. Plug your smartphone's charging cable into the external USB port

You can now charge it.

However, this is a point that is often misunderstood, as it cannot be used without a mobile battery . Also, there are cases where charging becomes unstable if the cable or port deteriorates.

2. Advantages of a suitcase with a USB port

Title

1. You can charge your smartphone while on the go

Title

Title

2. Convenient charging without having to remove the cable

Title

Previously, you had to take out the mobile battery directly to use it, but with a USB port , you can use the battery while it's stored inside your suitcase . This means no more tangled cables inside your bag, and it looks neater too.

Disadvantages of a suitcase with a USB port

Title

1. Reasons why charging may not be possible

Title

There are many people who say, "I have a USB port, but I can't charge my device." The main reasons for this are as follows:

  • No battery installed
  • Insufficient battery capacity or output
  • Internal wiring or port failure

As you can see, just because a device has a USB port doesn't mean it will charge smoothly.

Title

2. Obligation and hassle of removing the battery

Title

When boarding an airplane, you may need to remove the lithium-ion battery . Overseas airlines have strict regulations, and removing the battery every time can be a hassle.

Title

3. Many people feel that a USB port is unnecessary

Title

Many people think, "In the end, I can just use a mobile battery directly," which is why there are many cases where people end up barely using a suitcase with a USB port, even though they bought one.
Title

4. Suitcases with USB ports and carry-on luggage for airplanes and other aircraft

Title

1.Airline regulations and precautions (lithium-ion batteries)

Title

Most airlines prohibit lithium-ion batteries from being packed in checked baggage , a rule based on international safety standards to avoid the risk of fire.
Therefore, even if you are using a suitcase with a USB port, remember that you must remove the internal mobile battery and carry it on board .

There are also restrictions on battery capacity; generally, mobile batteries of 100Wh (watt-hours) or less can be carried on board without any problems, but for batteries with a capacity greater than that, you may need to apply for one from each airline.

Title

2. When can I bring it on board? When can I not?

Title
  • ✅ Suitcase with a removable USB port → If the battery can be easily removed, it can be used without any problems.
  • ❌Types with fixed batteries → There is a high possibility that many airlines will deny boarding to these types of aircraft.

Before purchasing, be sure to check whether the battery is removable .

5. Do you really need a USB port? Consider each case

Title

1. Recommended for people who travel frequently for business trips or long distances

Title

A suitcase with a USB port is a convenient choice for businessmen who travel frequently by plane or bullet train, or for those who travel abroad frequently .
You can charge your phone while rolling your suitcase, so you don't have to worry if your smartphone runs out of battery while you're traveling.

Title

2. Not necessary for those who carry a mobile battery

Title

On the other hand, for people who are used to carrying a small mobile battery with them, there is little need for a USB port.
In fact, many people feel that "it's faster to use a mobile battery directly" and "there's no need to go to the trouble of using a suitcase."

Recently, charging stations are increasingly being installed in airports, train stations, cafes, and other locations.
By using these spots in between trips, you can avoid running out of battery even if you don't have a suitcase with a USB port.
