Lithium batteries travel with you or they don't travel. What the rule says, what airlines usually ask and how to pack your bag for security.

There's a rule almost everyone breaks without knowing and that security enforces more and more: lithium batteries, power banks included, go in your hand luggage and never in the hold.

## Why it works that way

Because a lithium battery that overheats has to be visible and reachable. In the cabin someone notices and acts; in the hold, nobody does. It isn't an airport quirk, it's the entire reason for the rule.

## What goes where

| What | Cabin | Hold |
| --- | --- | --- |
| Power bank | Yes | No |
| Phone, tablet and laptop | Yes | Better not, and banned by many airlines |
| Chargers and cables | Yes | Yes |
| E-cigarettes | Yes, without using them | No |
| Loose spare batteries | Yes, with the contacts protected | No |

There are also capacity limits: large batteries need the airline's approval and very large ones aren't accepted at all. The capacity is printed on the battery itself, and if in doubt you ask before checking in, not at security.

## How to pack your bag for security

1. Everything electronic together and reachable, not scattered through the bag.
2. The power bank in an outside pocket, so you can pull it out without emptying everything.
3. Cables coiled up; on the scanner they're the image most likely to stop a tray.
4. The laptop out of its sleeve if you're asked, which is still standard at many airports.

## And what really matters on a long trip

That the power bank leaves home charged. It's the most repeated mistake: it goes into the bag, gets used at the first layover, and you land with both phone and power bank at zero — exactly when you need the map, the booking and a taxi.

The rest of the tricks for reaching the evening with battery are in [plugs and charging around the world](https://getgigapass.com/en/blog/travel-plug-adaptor).

The specific limits on capacity and quantity are set by each airline within the international framework. The source that counts is your own airline's site, and it varies from one to the next.

Know where you're going?

Pick your destination, days and data. Install it before you leave and pay once.

## Frequently asked questions

**Can I take a power bank on a plane?**

Yes, in your hand luggage. Lithium batteries aren't allowed in the hold, and a power bank is one.

**What if I check the bag with the battery inside?**

That's precisely what you can't do. If they spot it, you'll have to take it out, and if they don't, it travels where nobody can act if it fails.

**Is there a capacity limit?**

Yes, and it depends on the airline within the international framework: large ones need prior approval and very large ones aren't accepted.

**Can I carry several batteries?**

Usually yes, with the contacts protected and within the number of units your airline allows. Worth checking on their site before flying.
