Can you Bring a 10000mAh Power Bank on a Plane?

This is a completely legitimate concern, considering the strict and sometimes puzzling rules surrounding batteries and flights.

It’s no secret that we’ve all heard those unfortunate tales of folks having their valued power banks confiscated at airport security checkpoints.

In this blog post, I’m going to dig deep into the issue, decode aviation rules, and help you grasp what exactly the regulations are when it comes to carrying power banks on planes.

According to the Transportation Security Administration (TSA), you can bring a 10000mAh power bank onto an airplane, but only in your carry-on.

It’s critical to remember that TSA regulations strictly prohibit power banks in checked luggage, irrespective of their power capacity.

These rules can indeed be confusing. So, to simplify, here’s the lowdown on what you need to know about flying with a power bank:

  • Power banks are not permitted in checked luggage.
  • Power banks rated between 0-100Wh don’t require airline approval.
  • Power banks rated between 100-160Wh do require airline approval.
  • Power banks over 160Wh are prohibited on airplanes.

A 10000mAh power bank typically has a nominal power rating of 36Wh, which is well under the 100Wh limit set by the TSA. 

How many power banks can you take on a plane?

Wondering how many power banks you can take with you on a plane? Let’s break down the TSA rules for you, as they’re quite straightforward.

According to these regulations, you’re allowed to bring up to two power banks onto an airplane, as long as they comply with the watt-hour (Wh) limit. This is a per-passenger restriction, not per bag.

Be mindful of this limit. It’s easy to overlook the fact that even small portable chargers used for charging devices like vapes or smartwatches also count as power banks in the eyes of the TSA.

The TSA classifies a power bank as any device containing a lithium battery that’s capable of charging other electronic devices.

Interestingly, this means TSA agents could potentially categorize an item like an AirPod charging case as a power bank, since it contains a lithium battery.

Always remember: it’s better to be safe than sorry when traveling.

Paying attention to these details could save you a headache at the airport and ensure you stay connected during your journey.

Can TSA confiscate your 10000mAh power bank?

Curious as to why TSA agents might stop some individuals from bringing their power banks on board, even if their devices comply with TSA rules?

Though it’s infrequent, such instances can happen, and in most cases, the answer is quite simple: the power bank displays signs of external damage.

If your power bank is covered in cracks and you’ve resorted to using tape as a quick fix, be warned that airport security might view your device as a potential safety risk.

Consequently, they could prevent you from boarding the plane with it.

Remember, safety is a top priority when flying, and visibly damaged batteries can pose risks.

So, before heading to the airport, take a moment to inspect your power bank for any signs of wear and tear.

If it’s noticeably damaged, it might be time for an upgrade. 

How many watt hours is 10000mAh?

To find the answer, you first need to know the formula to calculate Wh (Watt-hours): Wh = mAh × V / 1000. Sounds complicated?

Don’t worry, it’s simpler than it seems.

For instance, if we’re looking at an Anker PowerCore 10000 Portable Charger

with a 10000mAh battery and a voltage of 3.6v, we calculate the watt-hours this way:

10000 x 3.6/1000 = 36 Wh. 

This falls well within the TSA limit of 100Wh.

So, the watt-hour rating for a 10000mAh power bank is 36Wh.

However, if the internal battery of your power bank has a voltage rating of 3.7v, then the watt-hour rating for the power bank would be 37Wh; 10000 x 3.7/1000 = 37 Wh.

Knowing the watt-hour rating of your power bank is crucial when preparing for air travel, as it determines whether or not you can bring your power bank onboard.

Why power banks aren’t allowed in checked luggage?

It’s all about safety, really. You see, power banks, including your 10000mAh one, contain a certain amount of lithium. In specific circumstances, these can overheat, catch fire, and even explode.

This risk is often due to low-quality components or manufacturing defects in the power bank’s battery.

External damage can also play a significant role. If your power bank is in checked luggage and subjected to rough handling or air turbulence, it could become damaged and potentially ignite.

Both the TSA and airlines understandably want to avoid this risk. However, when power banks are in the cabin, any potential danger is somewhat mitigated.


Because in the unlikely event of a fire, there’s always someone on hand to respond quickly and extinguish it.

So, while it might seem like a hassle to keep your power bank with you in the cabin, remember that these rules are in place to ensure the safety of everyone on board. 

What is the largest power bank you can take on a plane?

There are two primary scenarios to consider here, each depending on whether or not you have prior approval from your airline.

In the first scenario, if you don’t have pre-approval from the airline, your power bank needs to be under the 100Wh limit.

You can determine this by using the formula we discussed earlier: mAh × V / 1000. So, if we plug in the numbers (assuming an average voltage of 3.6v), a power bank you take onto an airplane should have a rating of just under 27000mAh (27000mAh x 3.6V / 1000 ≈ 100Wh).

Luckily, there are power banks on the market that fall just under this limit, such as certain models from Anker, which boast a rating of 26800mAh.

In the second scenario, with the airline’s approval, you can bring a power bank rated between 100-160Wh.

In mAh, this means you can bring a power bank with a capacity of up to around 43000mAh (remember, approval is necessary for this).

Technically speaking, the biggest power bank you can bring on a plane has a nominal energy level of 43000mAh, but only if you’ve secured the airline’s approval.

However, I’d advise that unless it’s absolutely necessary, you’re better off sticking to a power bank under the 27000mAh limit.

Here’s why: Even though airlines often give approval, it’s not guaranteed.

There might be a time when they simply say no, and there’s not much you can do about it.

Furthermore, the approval process varies among airlines. Some may ask you to send an email and await a response, while others might tell you that you’ll receive approval only at the airport checkpoint.

To avoid potential headaches, it might be best to stay on the safe side with a smaller power bank.

Should you buy a 26800mAh power bank if you already have a 10000mAh one?

Typically, a power bank can transfer about 70% of its capacity to other devices. You might wonder why I’m saying 70% when power banks are often advertised with over 80% or even 90% efficiency.

While it’s true that a power bank itself might have over 80% efficiency, this doesn’t account for the power efficiency of the device being charged, which brings us closer to the 70% figure.

In practical terms, this means a fully charged 10000mAh power bank provides around 7000mAh of usable power, while a 26800mAh one supplies approximately 18000mAh.

The difference, about 11000mAh, is quite substantial.

So, what does this number translate to in real-world use?

Well, an extra 11000mAh is enough to fully charge your smartphone from 0 to 100% about two additional times.

That’s significant, especially if you’re a frequent traveler or heavily reliant on your devices.

If this sounds like you, a 26800mAh power bank could be a great choice.

Just remember, your specific needs and usage patterns should guide your decision.

Consider how often you use your devices, how long you go between opportunities to charge them, and your travel habits when deciding on the right power bank for you.

Are power banks allowed on international flights?

Rest assured, power banks are generally allowed on international flights, as most airlines worldwide adhere to the same rules established by the TSA.

However, there’s an important caveat if your power bank falls within the 100-160Wh range.

These devices require pre-approval from the airline, and not all airlines may be accommodating.

Some around the globe might not allow such power banks onboard their planes.

Therefore, if you’re planning an international journey and wish to bring a higher-capacity power bank, it’s a good idea to contact the airlines ahead of time to understand their specific regulations.

And if you’re an avid world traveler or not yet sure about which airlines you’ll be flying with, I’d suggest sticking with a power bank under 100Wh (approximately 26800mAh).

This will keep you safely within universally accepted guidelines and could save you some hassle at security checks.

Remember, international travel can present complex scenarios with differing policies, so taking such proactive steps can contribute significantly to a smoother, more enjoyable journey.

What happened if you “forgot” your power bank inside your checked luggage?

Airport security personnel are specially trained to spot them, given the potential risks to airplane safety.

Typically, if an x-ray scanner detects a power bank, your suitcase will be opened and the power bank removed.

The good news?

You won’t typically be fined.

When you collect your luggage, you’ll likely find a ‘Notice of Baggage Inspection’ tucked inside, left by the TSA as a token of their visit.

However, be aware that international flights might throw a wrench into this process.

Certain jurisdictions might impose fines if they find a power bank in your checked luggage.

So, if you’re venturing across borders, it’s crucial to check out the specific rules and regulations of your destination country to avoid any unexpected fees or issues.

To sidestep these concerns altogether, I recommend always placing your power bank in your carry-on luggage. 

Do you need to take out your 10000mAh power bank at the airport?

According to TSA guidelines, any electronic device larger than a smartphone needs to be placed in a bin at the security checkpoint.

So if your power bank is relatively small, it can stay cozily nestled inside your carry-on luggage.

However, if you’re not quite sure where your power bank falls on the size spectrum, it’s safer to err on the side of caution.

In that case, go ahead and place it in the bin. It may take a few extra seconds, but it can streamline your passage through security and ensure you’re adhering to all TSA guidelines.

Remember, the goal is a smooth, hassle-free journey. By taking the time to understand and follow security protocols, you’re doing your part to ensure that not only your trip but also the trips of those around you go as smoothly as possible. 


In wrapping up, traveling with a 10000mAh power bank is completely permissible and hassle-free when you adhere to the TSA guidelines. These power banks are rated well within the TSA’s 100Wh limit for lithium batteries.

Remember, these rules are not there to make your life difficult; on the contrary, they are designed to ensure your safety and the safety of everyone else on board.

They’re there to make sure that your journey is as smooth and worry-free as possible.

So, as you prepare for your next journey, rest easy knowing you can keep your devices charged throughout your travels with your trusty power bank.

So, happy travels, and keep your devices charged up!
