Wizz Air Power Bank Rules 2026: Capacity, Quantity and More

The Wizz Air power bank rules are stricter than the general limits many UK travellers may be familiar with.

You can bring a power bank onboard, but Wizz Air currently limits passengers to one unit of no more than 100Wh. It must stay in the cabin where you can monitor it, cannot go in the overhead compartment, and cannot be used or recharged during the flight.

This guide explains the capacity limit, how to check your power bank’s Wh rating, where to pack it and recommended Anker power banks that fit Wizz Air’s current requirements.

Quick Answer: Does Wizz Air Allow Power Banks?

Yes. Wizz Air allows power banks on board, but its current rules are stricter than the general UK CAA baseline. Your power bank must be 100Wh or below, carried in the cabin and kept where you can monitor it throughout the flight.

• Maximum capacity: 100Wh per power bank, which equals roughly 27,000 mAh at 3.7V.
• Quantity: Maximum 1 power bank per passenger.
• Checked baggage: Not allowed.
• Overhead compartment: Not allowed.
• During the flight: The power bank cannot be used to charge another device or recharged at any stage of the flight.
• Storage: Keep it on your person, in an under-seat cabin bag or in the seat-back pocket.
• Labelling: The Wh rating must be clearly marked or otherwise calculable.

Wizz Air Power Bank Policy Explained

If you’re asking, “Can I take a power bank on plane Wizz Air?”, the answer is yes—as long as you follow the airline’s rules.

Wizz Air has stricter power bank rules than the general battery limits many travellers may be familiar with. According to Wizz Air’s official Restricted Items policy, the key requirements are:

Rule	Wizz Air policy
Maximum power bank capacity	100Wh
Maximum quantity	1 power bank per passenger
Checked baggage	Not allowed
Overhead compartment	Not allowed
Where to keep it	On your person, under the seat or in the seat-back pocket
Use during the flight	Not allowed
Recharge the power bank onboard	Not allowed
Capacity marking	Wh rating must be clear or otherwise calculable
Short-circuit protection	Required

The 100–160Wh Allowance Does Not Apply to Power Banks

This is an important distinction because Wizz Air’s policy also discusses lithium-ion batteries between 100Wh and 160Wh.

Those batteries may be accepted as spare batteries or batteries installed in equipment with prior Wizz Air approval, with no more than two qualifying spare batteries per passenger. That does not mean a 100–160Wh power bank is allowed.

Wizz Air lists power banks separately and explicitly states that power banks above 100Wh are forbidden. So, for example:

• A qualifying 120Wh spare battery may be considered with Wizz Air approval.
• A 120Wh power bank is not permitted.

Where Should You Keep Your Power Bank?

Your power bank must remain somewhere you can monitor it throughout the flight. Wizz Air does not allow power banks in checked baggage or in the overhead compartment.

The airline says they can instead be kept:

• on your person;
• inside cabin baggage stored under the seat in front of you; or
• in the seat-back pocket.

The terminals should also be protected against short circuits, for example by using the original packaging, insulating exposed terminals or keeping the power bank in a separate protective pouch.

Can You Use a Power Bank on a Wizz Air Flight?

No. Wizz Air states that power banks cannot be used during any phase of the flight.

That means you cannot:

• use the power bank to charge your phone, tablet or laptop; or
• recharge the power bank from an onboard power source.

So even if your power bank is below 100Wh and otherwise meets all of Wizz Air’s requirements, it should remain unused during the flight.

Finally, check that the battery information on the power bank is readable before travelling. Wizz Air prohibits power banks where the Wh rating is not clearly marked and cannot otherwise be calculated.

How to Check Your Power Bank’s Watt-Hour Rating

Wizz Air, like other airlines, uses watt-hours (Wh) rather than milliamp-hours (mAh) to determine whether a power bank meets its 100Wh limit. In many cases, you can find the Wh rating printed directly on the casing.

If only the capacity in mAh and the nominal battery voltage are shown, calculate it using:

Wh = (mAh × V) ÷ 1,000

For example, a 20,000mAh power bank with a nominal voltage of 3.7V works out to:

20,000 × 3.7 ÷ 1,000 = 74Wh

That puts it comfortably below Wizz Air’s 100Wh maximum.

Capacity	Approx. Wh at 3.7V	Wizz Air power bank status
5,000mAh	18.5Wh	Allowed
10,000mAh	37Wh	Allowed
20,000mAh	74Wh	Allowed
26,000mAh	96.2Wh	Allowed
27,000 mAh	99.9Wh	Allowed
30,000mAh	111Wh	Not permitted
50,000mAh	185Wh	Not permitted

These figures use 3.7V only as an example. If your power bank states a different nominal voltage, use that value instead. Where a Wh rating is printed on the product, use the manufacturer’s stated figure rather than an estimated conversion.

What Happens If Your Power Bank Exceeds 100Wh?

If your power bank is rated above 100Wh, Wizz Air will not accept it for carriage as a power bank. You should not rely on being able to request approval at the airport.

This is where Wizz Air differs from the broader UK CAA baseline. UK CAA rules provide an operator-approval route for some power banks above 100Wh and up to 160Wh, but airlines can impose stricter conditions. Wizz Air does exactly that: its current policy states that power banks exceeding 100Wh are forbidden.

If an oversized or unverified power bank is identified before boarding, you may need to leave it behind or make alternative arrangements before you can travel.

Why Power Banks Are Banned From Checked Luggage

Power banks contain rechargeable lithium batteries, which can overheat if they are damaged, defective or short-circuited. In more serious cases, a lithium battery can enter thermal runaway, generating enough heat to catch fire and potentially affect nearby batteries or materials.

Keeping power banks in the cabin makes a developing problem easier to notice and respond to than if the battery were inaccessible in the aircraft hold. This is why both UK CAA guidance and Wizz Air require power banks to travel in carry-on baggage rather than checked luggage.

If your cabin bag is being placed in the hold at the gate, remove the power bank before handing the bag over and keep it with you in the cabin.

How Wizz Air Compares With Other Budget Airlines Serving the UK

Power banks must stay out of checked baggage across these airlines, but the limits are not identical. Wizz Air is currently stricter than several other budget carriers, particularly on capacity, quantity and onboard use.

Airline	Power bank capacity	Maximum quantity	Use onboard
Wizz Air	≤100Wh only	1	Not allowed at any stage
Ryanair	≤100Wh only	2	Device charging allowed except taxi, take-off and landing / crew restrictions
easyJet	Up to 160Wh with automatic operator approval where required	2	Not allowed
Jet2	Up to 160Wh, with automatic operator approval over 100Wh	2	Not allowed

The biggest difference is that Wizz Air allows only one power bank and caps it at 100Wh.

Ryanair also sets a 100Wh maximum but allows up to two power banks. It permits power banks to charge personal devices during the flight except during taxi, take-off and landing, or when crew instruct otherwise.

easyJet and Jet2 are more flexible on capacity, accepting power banks up to 160Wh and allowing up to two per passenger. easyJet gives automatic operator approval for lithium-ion batteries up to 160Wh, while Jet2 specifically gives automatic operator approval to power banks above 100Wh and up to 160Wh.

Storage rules also differ slightly. Wizz Air and Ryanair specifically prohibit power banks from overhead compartments, while Jet2 requires the cabin bag containing the power bank to be stored under the seat. easyJet recommends keeping power banks somewhere they can be monitored, such as on your person.

Recommended Flight-Safe Anker Power Banks for Travel

• Smart monitoring on the go: The AnkerSense display and Anker app show battery level, charging status and individual port output, making it easier to manage several devices from one power source.

Conclusion

The current Wizz Air power bank rules are stricter than the general UK CAA baseline: bring no more than one power bank, keep it at 100Wh or below, and carry it somewhere in the cabin where you can monitor it.

Do not place it in checked baggage or the overhead compartment, and do not use or recharge it during the flight. All four Anker models featured above fall below Wizz Air’s 100Wh capacity ceiling, so you can choose the one that best matches your devices and travel needs.

FAQs

Can I bring a 37 Wh power bank on a plane?

Yes, easily. A 37 Wh power bank, roughly 10,000 mAh at 3.7 V, sits far below the 100 Wh limit, so it needs no airline approval on Wizz Air or any UK carrier. Pack it in your hand luggage, keep it within reach, and you are ready to fly.

Does Wizz Air weigh hand luggage?

Yes, Wizz Air sets a 10kg maximum for both its free carry-on bag and the additional WIZZ Priority trolley bag, so you should pack within that limit. The free carry-on bag can measure up to 40 × 30 × 20cm and must fit under the seat. With WIZZ Priority, you can also bring a trolley bag up to 55 × 40 × 23cm, also with a 10kg maximum. Bags that exceed the permitted size or weight may incur additional charges.

Can I take my handbag as well as hand luggage on Wizz Air?

Not as an additional free bag. Every Wizz Air passenger can bring one free carry-on bag measuring up to 40 × 30 × 20cm and weighing up to 10kg. That bag can itself be a handbag, purse, laptop bag, briefcase or small backpack. If you want to bring both that personal bag and a separate cabin trolley, you need WIZZ Priority, which adds a second trolley bag of up to 55 × 40 × 23cm and 10kg.
