Can You Bring Power Packs On A Plane? | Carry-On Only

A power bank looks harmless — a brick of backup juice for your phone. Most people assume it packs like any other gadget. Airlines see it differently. The rules for bringing power packs on a plane are tighter than expected, and getting them wrong can slow you down at security or even get your bag pulled. The good news is that the standard portable charger you carry daily likely fits the rules without any hassle.

The honest answer is straightforward: power banks go in carry-on bags only. If your pack is under 100 watt-hours (which covers most common sizes), TSA allows it without special approval. Larger packs between 100 and 160 Wh need a quick call to your airline. Anything over 160 Wh stays home. This guide breaks down exactly what to check before you pack.

The Basic Rule: Carry-On Only

TSA is clear: portable chargers and power banks containing lithium ion batteries must be packed in carry-on baggage. They are strictly prohibited in checked luggage. Devices like laptops and phones with built-in batteries can go in checked bags, but spare batteries and power banks stay with you in the cabin.

Common power bank sizes — 10,000 mAh, 20,000 mAh, 25,000 mAh, and 27,000 mAh — all fall under the 100 Wh limit. That means most everyday power packs are allowed without any extra steps. The FAA notes that 100 Wh is roughly equivalent to 27,000 mAh, so anything at or below that is fine.

One more thing: you cannot use the power bank to charge your device during the flight. The FAA prohibits in-flight use and recharging of power banks on board. Charge everything before you board or wait until you land. Spare lithium batteries follow the same carry-on requirement, and you should keep them in original packaging or tape terminals to prevent short circuits.

Why The Rule Exists — And Why People Get It Wrong

Lithium batteries can overheat and catch fire. That’s not a theoretical risk — recent recalls show the danger is real. The regulations exist to keep any potential fire in the passenger cabin, where flight crews can respond, rather than in the cargo hold where a fire could go unnoticed. That’s why power banks are banned from checked luggage.

• Anker power banks: More than one million Anker power banks were recalled in June 2025 due to fire and burn hazards from lithium-ion battery overheating.
• Casely wireless power banks: Re-recalled in April 2026 after one fatality was reported, following a 2025 recall, due to fire and burn risks.
• Yiisonger power banks: The CPSC warned consumers to stop using Yiisonger power banks sold on Amazon due to overheating and fire hazards.
• VEEKTOMX mini power banks: Recalled in 2026 after fire and burn hazards were identified, sold through Amazon.
• INIU power banks: Also recalled due to fire risks from lithium-ion battery overheating, sold on Amazon.

Damaged or recalled power banks should never be packed in any luggage. If your power bank shows signs of swelling, damage, or is part of a recall, leave it at home. The CPSC advises immediate disposal of recalled models through proper recycling channels.

How To Check Your Power Pack Capacity

The watt-hour rating is the key number. Most power banks list it on the label or in the product specs. If you only see milliampere-hours (mAh), divide by 1000 and multiply by the voltage (usually 3.7V) to get a rough Wh. Per the TSA power bank carry-on rule, anything under 100 Wh is fine.

A simple rule of thumb: 27,000 mAh or less is under 100 Wh. That covers most personal power banks. If you have a larger model, check the number carefully before heading to the airport.

If your power bank falls into the 30,000 mAh or above range, contact the airline before your trip. They may allow up to two units between 100 and 160 Wh, but approval is per airline policy.

What About Larger Packs And Multiple Banks?

Power banks between 100 and 160 Wh are not automatically banned, but they do need the airline’s green light. You can carry up to two such units with approval. Any single pack over 160 Wh is forbidden on passenger aircraft under US regulations. If your power bank does not have a clear watt-hour label, TSA considers it prohibited.

1. Check the watt-hour rating on the label. If it’s between 100 and 160 Wh, contact the airline before booking or at least 24 hours before departure. The airline may require a specific approval form.
2. Limit yourself to two approved packs. Even with approval, only two units in the 100–160 Wh range are permitted per passenger. Keep the approval confirmation with your boarding pass.
3. Never pack a damaged or recalled power bank. Recalled models are a fire risk and will likely be confiscated if spotted. If the battery is swollen, leave it at home.
4. For packs 30,000 mAh and above, or any 40,000 mAh pack, expect to need airline permission. These likely exceed 100 Wh based on the standard conversion. Check the exact Wh rating on the label.
5. Keep the power bank accessible during security screening. You may be asked to remove it from your bag for separate inspection. Having it easy to reach speeds up the process.

Larger power banks designed for camping or heavy-duty use are rare on flights. If you absolutely need one for work or medical reasons, get written confirmation from the airline to avoid issues at the gate.

What Security Screeners Look For

At security, power banks stay in the carry-on. They are not typically removed for X-ray, but if the bag appears dense, officers may ask you to take them out. Having the power bank easy to reach speeds things up. Remember that power banks cannot be used during the flight, so turn off your device before boarding if you need to conserve charge.

The FAA reinforces that all spare lithium batteries must travel in the cabin — see the FAA spare battery cabin rule for the full policy. This includes power banks, which are treated as spare batteries even if they are in their original packaging.

If additional screening is needed, the officer may test the battery with a special wand or ask you to turn the device on. A charged power bank that powers up without issue passes quickly. If the battery appears damaged or swollen, expect it to be denied. Keep your power bank away from metal objects and liquids in your bag to avoid confusion on the X-ray screen.

Use this as a quick pre-departure checklist. Double-check the label and confirm with your airline if there’s any doubt. Keeping the rules straight means no surprises at the checkpoint.

The Bottom Line

Power packs are allowed on planes, but only in carry-on bags. Stick to packs under 100 Wh (about 27,000 mAh) for hassle-free travel. Larger ones between 100 and 160 Wh need airline approval, and anything above 160 Wh stays home. Check the label, avoid recalled models, and pack your power bank where you can access it if asked.

Before your next flight, look up the exact watt-hour rating on your power bank and confirm with your airline if you are carrying a high-capacity model. Your airline’s customer service can give you the final green light for that specific pack and your itinerary.
