Ryanair Power Bank Rules: What Can You Take on Your Flight?

Whether you’re heading off for a city break, a beach holiday, or a quick work trip, a power bank can save you from the stress of a low battery at the worst possible moment. But before you pack one, it’s worth checking the airline’s rules.

If you’re travelling with Ryanair, there are clear limits on where it can be packed and how much battery capacity you can bring onboard. In this guide, we’ll break down the Ryanair power bank rules, explain what size makes sense for different types of trips, and share some flight-safe options that are easy to travel with.

Quick Answer: Can You Take a Power Bank on Ryanair?

Yes, you can take a power bank on Ryanair flights, but it must be carried in your cabin bag or on your person — never in checked luggage. Each unit must be under 100Wh, which covers most consumer power banks, including 5,000–25,000mAh models.

You can bring up to 20 spare batteries, provided each is protected against short circuits. Keep power banks under the seat, not in the overhead locker, and don’t use them during taxi, take-off, or landing. Follow these Ryanair power bank rules, and your devices can stay charged safely throughout your flight.

Ryanair Power Bank Rules Explained

Ryanair allows power banks onboard, but there are a few important rules to follow. The key is knowing where to pack them and how much capacity is allowed.

Keep Power Banks in Your Cabin Bag

Power banks contain lithium batteries, which can pose a fire risk if damaged or overheated, so they must be carried in your hand luggage. They are not allowed in checked baggage under any circumstances.

If your cabin bag is taken at the gate and placed in the hold, make sure you remove any power banks first and keep them with you.

The Maximum Capacity Is 100Wh

The Ryanair power bank limit is 100Wh. Anything above this capacity is not permitted in either the cabin or the hold.

If you’re more familiar with mAh ratings, here’s a rough guide (assuming a nominal battery cell voltage of 3.7V):

Power Bank Capacity	Approximate Wh	Allowed on Ryanair?
5,000mAh	18.5Wh	Yes
10,000mAh	37Wh	Yes
20,000mAh	74Wh	Yes
25,000mAh	92.5Wh	Yes
27,000mAh	99.9Wh	Yes
30,000mAh	111Wh	No

Most travel-friendly power banks sold today fall comfortably below the 100Wh threshold, which is why they are generally suitable for flights.

You Can Bring Multiple Power Banks

Ryanair allows passengers to carry up to 20 spare lithium batteries or power banks, provided each one is under 100Wh. That's far more than most people would ever need, but it can be useful if you're travelling with multiple devices or sharing chargers with family members.

Protect Spare Batteries Properly

Power banks and spare batteries should be protected against short circuits during travel. Ryanair recommends keeping them in their original packaging, placing them in individual protective pouches, or covering exposed terminals with tape.

Don’t Store Them in the Overhead Locker

This is a rule many travellers miss. Ryanair specifically states that power banks should not be placed in cabin baggage stored in the overhead lockers. Instead, keep them in the small bag under the seat in front of you or carry them on your person. This makes them easier to access if a battery overheats or becomes damaged.

Can You Use a Power Bank During the Flight?

Yes, but not throughout the entire journey. Ryanair says power banks should NOT be used to charge devices during taxi, take-off, or landing. Once the aircraft is cruising and cabin crew permit the use of electronic devices, you can generally use your power bank as normal.

What Size Power Bank Do You Need for Your Travel?

The best power bank size depends on how long you'll be travelling, how heavily you use your devices, and whether you'll have regular access to charging points.

While Ryanair allows power banks up to 100Wh, most travellers don't need anything close to that limit. In fact, a 10,000mAh or 20,000mAh model is usually enough for holidays, city breaks, and business trips.

Use the table below as a quick guide:

Travel Scenario	Recommended Capacity	Typical Use
Short flight, daily charging available	5,000mAh	Emergency top-ups, boarding passes, maps, messaging
Weekend city break (2–3 days)	10,000mAh	1–2 full phone charges, ideal for sightseeing and travel apps
Week-long holiday with regular charging access	20,000mAh	Multiple phone charges, suitable for heavier daily use
Long travel days, camping, or multiple devices	25,000mAh	Power for phones, tablets, earbuds, and extended time away from plug sockets
Laptop charging during travel	20,000–25,000mAh with USB-C PD	Suitable for compatible laptops and power-hungry devices

Best Flight-Safe Power Banks from Anker

Now that you have a clearer idea of what size power bank suits your trip, it’s easier to choose a model that fits both Ryanair’s rules and your travel needs.

Whether you’re looking for a compact 5,000mAh charger for short flights, a 10,000–20,000mAh option for longer trips, or something with extra power for multiple devices, Anker offers a range of flight-safe power banks that combine portability and reliability.

Below, we’ve selected the best options to keep your devices charged and your journey hassle-free.

Anker Nano Power Bank 5,000mAh

For those who want backup power without adding much bulk, the Anker Nano Power Bank 5,000mAh is a particularly easy travel companion. Its slim magnetic design attaches neatly to MagSafe-compatible iPhones, so you can top up your phone while checking boarding passes, using maps, or waiting at the gate without juggling a cable.

With 15W Qi2-certified wireless charging, it can charge an iPhone 16 Pro to 25% in about 42 minutes. When you need faster charging, the 20W USB-C port gives you a wired option with more power. The 5,000mAh capacity is best treated as top-up power rather than a guaranteed full recharge, which makes it a good fit if you mainly need enough extra battery to get through the day.

At just 122g and 8.6mm thick, it is easy to keep in a small cabin bag or jacket pocket. Graphene heat dissipation and dual NTC temperature control help manage warmth during wireless charging, which is useful when the power bank is magnetically attached and you are still using your phone.

Best for: iPhone users who want a slim magnetic power bank for short flights, city breaks, airport days, and light phone top-ups.

The built-in 70cm retractable USB-C cable is the travel-friendly detail that makes this model stand out. You do not need to remember a separate cable, but you still get enough length to charge comfortably while using your phone at your seat, in the airport lounge, or on the train after landing. The smart display is also useful before boarding, showing remaining battery and power flow at a glance.

With up to 45W max output via USB-C, it can handle compatible phones, tablets, and smaller USB-C devices more confidently than a basic mini power bank. ActiveShield 3.0 monitors temperature during charging, giving extra reassurance when the charger is working in a packed bag or busy travel setting.

FAQs

Can I carry a 30,000mAh power bank in flight?

Yes, you can usually carry a 30,000mAh power bank on a flight, but it often requires airline approval. A 30,000mAh power bank typically has a rating of around 111Wh, which places it within the 100Wh to 160Wh range under UK Civil Aviation Authority (CAA) rules. This means it is allowed in hand luggage but needs airline approval before travel. Power banks are treated as spare lithium-ion batteries because they can overheat and catch fire if damaged, so they are not allowed in checked baggage.

What is the maximum capacity power bank on Ryanair?

The Ryanair power bank limit is 100Wh (about 27,000 mAh) per battery, which is the maximum capacity allowed on board. Power banks must be carried in hand luggage only, as batteries within this limit are generally approved for cabin travel and do not usually require airline permission.

Can you take a 20000mAh power bank in carry-on luggage?

Yes, you can take a 20,000mAh power bank in carry-on luggage. A 20,000mAh power bank typically equals 74Wh, which falls below the 100Wh limit set by the UK Civil Aviation Authority (CAA). This means it is generally allowed without airline approval, but it must be packed in hand luggage rather than checked baggage.
