Can You Bring a Power Bank on a Plane?
Can You Bring a Power Bank on a Plane? TSA Rules 2026
If you're packing for a trip, a power bank can be one of the most useful things in your bag. It can keep your phone, earbuds, tablet, camera, or other USB-powered devices charged when you're away from an outlet.
But there's an important question before you head to the airport:
Can you bring a power bank on a plane?
Yes — but power banks have to follow specific battery and baggage rules.
For travelers flying in the United States, the basic rule is simple: keep your power bank in your carry-on bag, not your checked luggage, and check its watt-hour (Wh) rating before you fly.
The Quick Answer
For most everyday travelers:
- Power banks are allowed on planes when they meet the applicable battery requirements.
- Power banks must be carried in your carry-on baggage.
- Power banks cannot be packed in checked luggage.
- Batteries rated up to 100 Wh are generally allowed.
- Batteries rated 101–160 Wh generally require airline approval.
- Batteries over 160 Wh are not permitted on passenger aircraft.
- Your airline may have additional restrictions.
The important detail is that mAh alone doesn't determine whether a power bank is allowed. Aviation rules use watt-hours (Wh) to measure battery energy.
For the latest official passenger guidance, check the FAA PackSafe battery guidance and the TSA What Can I Bring guidance.
Why Do Power Banks Have to Go in Your Carry-On?
A power bank contains a rechargeable lithium battery.
Lithium batteries can potentially overheat or experience thermal runaway if they are damaged, defective, overheated, or otherwise compromised. Keeping spare lithium batteries in the passenger cabin allows flight crews to respond more quickly if a battery develops a problem.
That's why spare lithium batteries, including power banks and portable chargers, must be carried in the cabin rather than checked baggage.
So when you're packing:
Power bank → carry-on bag
Power bank → not checked luggage
This is one of the easiest travel rules to remember.
What Is the 100 Wh Power Bank Rule?
The most important number to understand is 100 Wh.
Under current FAA guidance, rechargeable batteries from 0–100 Wh are generally allowed on passenger aircraft.
Batteries from 101–160 Wh can be carried with airline approval, subject to additional restrictions.
Batteries exceeding 160 Wh are not permitted on passenger aircraft.
Airlines can also establish stricter requirements, so checking with your airline before departure is important.
How Do You Calculate Watt-Hours?
Power banks are often advertised using mAh, while aviation rules use Wh.
You can calculate watt-hours using:
Wh = Volts × Amp-hours
If the battery is listed in milliamp-hours:
Wh = Voltage × (mAh ÷ 1,000)
For example, if a battery is rated at 20,000mAh and its nominal voltage is 3.7V:
3.7 × 20 = 74 Wh
That is below the 100 Wh threshold.
However, don't rely only on a calculation if the manufacturer has already printed a Wh rating on the power bank. Use the rating shown on the actual battery or product documentation when available.
Can You Bring a 20,000mAh Power Bank on a Plane?
A 20,000mAh power bank can generally be suitable for air travel, but mAh by itself isn't the aviation limit.
You should check the battery's stated watt-hour rating.
For example, BaseMaxCore's JUOVI 20,000mAh 45W Power Bank is designed for portable charging and provides up to 45W USB-C output, with one USB-C port and two USB-A ports.
For air travel, however, the important number to verify is the battery's Wh rating, not simply the 20,000mAh marketing capacity.
That distinction is worth remembering whenever you're shopping for a travel power bank.
Can You Put a Power Bank in Checked Luggage?
No.
Spare lithium-ion batteries, including power banks and portable chargers, must be carried in your carry-on baggage, not checked luggage.
This applies even when the power bank is switched off.
So don't put your portable charger inside your checked suitcase just because you aren't planning to use it during the flight.
Keep it with you in the cabin instead.
If you want to understand how portable batteries compare with larger backup systems, see our guide to Power Station vs. Power Bank.
Can You Bring More Than One Power Bank?
There isn't one universal number that applies to every passenger and every airline.
FAA guidance allows rechargeable batteries under 100 Wh for personal use, while larger 101–160 Wh spare batteries are subject to additional restrictions.
Airlines can establish stricter limits.
If you're traveling with multiple power banks, especially larger-capacity models, check your airline's current battery policy before leaving for the airport.
What About a 10,000mAh Power Bank?
A typical 10,000mAh portable charger is commonly used for phones and other small devices.
As with a 20,000mAh model, the important thing for air travel is its watt-hour rating and whether the battery complies with the airline's requirements.
Don't assume that every product with the same mAh number has exactly the same Wh rating.
When shopping for a travel power bank, look for clearly stated battery specifications.
What About a 5,000mAh Mini Power Bank?
Smaller power banks can be convenient for short trips because they're easier to carry.
A compact model can make sense when you mainly need emergency phone charging rather than enough capacity for several devices.
For example, BaseMaxCore's Mini 5,000mAh Power Bank is designed around portability, making this type of power bank useful for short outings, commuting, and situations where you don't want to carry a larger battery.
Before flying, you should still check the product's battery specifications and your airline's rules.
How Should You Pack a Power Bank for a Flight?
A little preparation can make airport screening easier.
1. Keep it in your carry-on
Don't put your spare power bank in checked baggage.
2. Protect the power bank from damage
Avoid packing it where it can easily be crushed or damaged.
3. Prevent short circuits
Keep exposed battery terminals from coming into contact with metal objects.
If your power bank has built-in protection around its ports, keep the device in good condition and avoid carrying damaged cables or accessories.
4. Don't travel with a damaged battery
A swollen, damaged, leaking, recalled, or otherwise compromised lithium battery should not be taken onto an aircraft.
If a power bank looks damaged, replace it rather than trying to take it through airport security.
5. Keep the specifications accessible
If your power bank has its capacity or Wh rating printed on the device, don't cover the label.
Clear battery information can be useful if security personnel need to inspect the device.
What If Your Power Bank Is Over 100 Wh?
This is where you should stop and check before traveling.
For a battery between 101 and 160 Wh, airline approval is required under FAA guidance, along with additional restrictions.
Don't simply assume that because a power bank is sold commercially, you can take it on your flight.
Check the exact Wh rating and contact your airline if necessary.
For batteries over 160 Wh, passenger aircraft restrictions are much stricter and such batteries are not permitted for ordinary passenger travel.
Power Banks vs. Power Stations for Travel
A power bank and a portable power station aren't the same thing.
A power bank is generally designed to charge smaller electronics such as:
- Smartphones
- Earbuds
- Tablets
- Smartwatches
- Cameras
- Other USB devices
A portable power station is designed for much larger loads and often includes AC outlets and substantially greater battery capacity.
That makes power stations useful for camping, emergency backup, and off-grid situations, but their size and battery capacity can create different transportation restrictions.

Choosing a Power Bank for Air Travel
If you frequently travel, don't choose a power bank based only on the largest mAh number.
Instead, consider:
Battery rating: Check the Wh rating and make sure you understand the airline restrictions.
Size: A smaller power bank is easier to carry through airports.
Charging speed: USB-C Power Delivery can provide faster charging for compatible devices.
Ports: Multiple ports are useful if you're traveling with a phone, earbuds, tablet, or other electronics.
Battery display: A percentage display can make it easier to know when your power bank needs to be recharged.
Build quality: Choose a reputable product and avoid batteries that are damaged, swollen, or poorly constructed.
Airline compatibility: Always check the rules of the airline you're actually flying with.

A Practical Travel Charging Setup
For a typical trip, you don't need to carry every charging accessory you own.
A simple setup might include:
Phone + USB-C cable + power bank + wall charger
If you're traveling with multiple devices, a higher-capacity power bank with several charging ports can reduce the number of accessories you need to carry.
The JUOVI 20,000mAh 45W Power Bank is one example, offering up to 45W USB-C output, one USB-C port, two USB-A ports, and an LED battery display.
Just remember: product capacity and charging speed are separate from airline eligibility. Always verify the battery's Wh rating and your airline's current requirements before flying.

Common Power Bank Travel Mistakes
Putting the power bank in checked luggage
This is one of the easiest mistakes to avoid.
Keep spare lithium-ion batteries and power banks in your carry-on.
Looking only at mAh
A 20,000mAh label doesn't tell you everything you need to know about airline restrictions.
Check the Wh rating.
Assuming every airline has identical rules
Airlines can impose stricter requirements than the baseline aviation rules.
Check your specific carrier before your trip.
Traveling with a damaged battery
Don't take chances with a swollen, damaged, recalled, or overheating power bank.
Replace it before traveling.
Buying the biggest power bank possible
More capacity isn't automatically better for travel.
A smaller power bank may be more convenient if you're only trying to keep your phone charged during a day of sightseeing.
