Do Smart Luggage Tags Need Batteries? What Travellers Should Know Before Flying

We travel with more technology than ever.

Phones.

Headphones.

Smartwatches.

Tablets.

Power banks.

Location trackers.

Even our luggage is becoming smarter.

At the same time, airlines, airports and aviation regulators are becoming increasingly vocal about how battery-powered devices should be packed when we fly.

It raises an interesting question.

Does every smart product we attach to our luggage actually need another battery?

The answer is no.

And understanding the difference between battery-powered tracking, powered smart luggage and passive identification can make preparing for your next flight a little simpler.

Why batteries in luggage are getting more attention

Lithium batteries power much of the technology we carry every day.

For the vast majority of the time, they do that safely.

But aviation authorities are particularly careful about batteries because damaged, faulty or incorrectly packed lithium batteries can overheat and create a fire risk.

In July 2026, the UK Civil Aviation Authority warned passengers to “pack right for a safe flight” as millions prepared for their summer holidays.

The regulator estimated that around 30 million passengers would leave the UK during July and August, with the average traveller carrying four lithium-powered devices.

It also reported that incidents involving overheating or malfunctioning passenger devices had nearly doubled between 2024 and 2025.

The message is not that passengers should stop travelling with technology.

It is that we need to understand what we are carrying and where it should be packed.

Power banks and spare batteries need particular care

Different types of battery-powered products are treated differently.

Power banks and spare lithium batteries should not be packed in checked baggage and generally need to travel with the passenger in the cabin.

Vapes are also subject to specific restrictions.

Manchester Airport reinforced that message in August 2026, warning passengers that incorrectly packed battery-powered items can be removed when checked baggage is screened.

The exact requirements can vary by airline, destination and type of device, so travellers should always check the current rules for the airline they are flying with.

But there is a useful wider lesson.

Not everything described as “smart luggage technology” works in the same way.

Are AirTags allowed in checked luggage?

This is where the distinction matters.

Small location trackers such as an Apple AirTag contain a battery.

But that does not mean they are automatically prohibited from checked luggage.

International aviation rules include an exception for small, low-energy baggage tracking devices within defined battery limits.

British Airways, for example, allows compliant smart baggage tags such as AirTags to remain active in checked luggage where the battery falls within those limits.

Other airlines may have their own requirements.

So if you use a battery-powered location tracker, check the policy of the airline operating your flight before you travel.

The important point is this:

Battery-powered trackers have a legitimate role.

They can help an owner understand where their luggage is.

But tracking is only one type of smart luggage technology.

“Smart luggage” can mean several different things

The word smart gets used very broadly.

A smart suitcase might contain a power bank for charging your phone.

Another might contain electronic scales, locks or other powered features.

A location tracker may use Bluetooth and a battery to help determine where a bag is.

And a smart identification tag can use a QR code to create a digital connection between a physical item and its owner.

Those technologies do different jobs.

And they do not all need power.

Smart doesn't always have to mean powered

A QR code is passive.

It does not transmit a signal.

It does not require charging.

And it does not need a battery in order to be scanned.

With TagLink, for example, somebody who finds a suitcase or travel bag can scan the physical QR code using the camera already built into their smartphone.

The technology needed to make the connection is in the finder's phone, not inside the TagLink.

There is:

• no battery inside the tag

• nothing to charge

• no battery to replace

• no power switch

• no subscription

• no app for the finder to download

The finder scans the TagLink and can securely send the owner a message.

Scan. Message. Return.

That makes it smart identification without requiring another powered device on your luggage.

Battery-free doesn't mean better at everything

There is an important distinction here.

A battery-free QR tag is not a replacement for GPS or Bluetooth tracking.

TagLink cannot show you the location of your suitcase.

An AirTag or another compatible location tracker can.

Likewise, an AirTag is not designed primarily to create a visible contact route for a stranger standing next to your bag.

These are different tools solving different problems.

Location tracking asks: Where is my bag?

Smart identification asks: Someone has found my bag. How can they reach me?

For travellers who want both, there is no reason the technologies cannot complement each other.

A useful way to think about travel technology

Before adding another piece of technology to your luggage, ask what job you actually want it to do.

If you want to see where your bag is, a compatible location tracker may be useful.

If you want to charge devices while travelling, a power bank may be useful, although it needs to be packed according to airline battery rules.

If you want somebody who finds your luggage to have an obvious route to contact you, a smart identification tag can provide that.

Different problem.

Different technology.

And sometimes the simplest technology is enough.

Does battery-free matter?

For something attached to luggage, there are a few practical advantages.

There is nothing to remember to charge before a trip.

There is no battery that gradually runs down while the tag sits unused between holidays.

There is no battery to replace.

And a passive QR identification tag does not introduce another lithium-powered device into your packing.

That doesn't make powered travel technology bad.

It simply means power should serve a purpose.

If a product can do its job without a battery, there can be real value in keeping it that simple.

A simple battery check before you fly

Before your next journey:

1. Check what technology you're taking

Phones, watches, headphones, tablets, cameras, power banks and trackers may all contain batteries.

2. Keep power banks and spare batteries out of checked luggage

These generally need to travel with you in the cabin.

3. Check your airline's current rules

Requirements can vary between airlines, routes and types of device.

4. Check anything built into your suitcase

If your luggage contains a power bank or another significant battery, understand whether it needs to be removed before the bag can be checked.

5. Check your tracker

Small compliant baggage trackers are generally permitted, but check your airline's requirements.

6. Don't travel with damaged batteries

If a battery is swollen, overheating, damaged or behaving unusually, don't pack it for a flight.

7. Decide what you actually need your luggage technology to do

Tracking, identification and charging are separate functions. You may not need one device to perform all three.

Smart travel can also be simple travel

Technology has transformed the way we travel.

And that is largely a good thing.

Better airline baggage systems can help manage luggage through airports.

Location trackers can give travellers useful visibility when something goes missing.

Phones put boarding passes, maps, tickets and communication in our pockets.

But innovation doesn't always have to mean adding another powered device.

Sometimes the clever part is removing complexity.

A physical tag.

A QR code.

A smartphone somebody already owns.

And a simple way to reconnect a found item with the person it belongs to.

Smart doesn't always have to mean powered.
