Traveling with Power Banks: Rules, Flights & Best Practices

Traveling often means staying connected, especially with our phones, tablets, and laptops. But these devices can run out of battery quickly. That's where power banks come in. A small portable power bank can keep you powered up on the go.

Why Power Banks Are Non-Negotiable Travel Gear

Imagine being on a long flight or a road trip with a dying phone. Without a power bank, staying connected could be difficult.

• A power bank gives you the freedom to keep your devices charged, no matter where you are.
• If you’re flying, keeping your phone or tablet charged is easier with a portable power bank.
• Having a backup power source can ease the stress of relying on public chargers, which may not always be available.
• Portable power banks are compact and lightweight, making them perfect travel companions.
• You can use a power bank to charge phones, cameras, laptops, and other essential devices during your journey.

Can You Take a Power Bank on a Plane?

Yes  , you can bring a power bank on a plane, but there are rules to follow:

• Power banks must be placed in your carry-on bag , not in checked luggage.
• If you have extra power banks or spare batteries, they must also be kept in your carry-on.
• The terminals of your power bank should be protected to avoid short circuits . You can use tape, a case, or a plastic bag to cover the terminals.
• Most airlines allow power banks up to 100 watt-hours (Wh) . For larger batteries (101–160 Wh), you need the airline's approval.
• You can usually carry two spare power banks of up to 160 Wh, but they must be for personal use only .

Why Is There a 100 watt-hours (Wh) Limit?

Here’s why the limit exists:

• Safety : Lithium batteries, like the ones used in power banks, can catch fire or overheat . Keeping the size below 100 Wh reduces the risk of a dangerous situation.
• Smaller energy output : A 100 Wh battery has enough power for personal devices but is small enough to be safely managed in an emergency.
• Standard limit : This is a universally recognized standard. It ensures a balance between practicality (keeping your devices powered) and safety.
• Easy to follow : The 100 Wh rule helps passengers and airlines manage the batteries consistently. Without such rules, it could be hard to decide which batteries are safe to bring. To check if your battery meets the rule, you can use this simple formula: Watt-hours (Wh) = Voltage (V) × Capacity (Ah).

Best Practices for Traveling with Power Banks

To get the most out of your power bank and stay safe while traveling, follow these best practices:

• Avoid cheap or unbranded power banks . Certified models follow strict safety standards. Poor-quality units are more likely to overheat or fail.
• If your power bank doesn't show the Wh rating, write it clearly on a tag or sticker . Security checks may delay your trip if officers cannot verify the battery size.
• Charging from unstable car or train power outlets can harm the power bank's internal battery . Wait until you're at a stable power source, like a hotel or airport lounge.
• Packing multiple power banks on top of each other can trap heat. Always separate them with fabric or a pouch to avoid temperature buildup.
• A swollen or discolored power bank could mean internal damage . Don’t bring it on a trip. Dispose of it safely before you go.
• Store your power bank under the seat in front of you . If a problem occurs, it's easier to act fast when it's within reach—not locked away overhead.
