Can you bring portable chargers on a plane?

Many people wonder if it is possible to bring a portable charger or power bank on a plane, and the short answer is yes, they are allowed in carry-on baggage.

According to the International Air Transport Association (IATA), in its Dangerous Goods Regulations, the power bank is “considered” as a spare battery and is governed by the following rules:

  1. It must be packed in carry-on baggage.
  2. A maximum of 20 units may be carriedΒ without prior approval of the flight operator, provided that the total rated capacity does not exceed 100 Wh.
  3. A maximum of 2 units may be carried, subject to the approval of the flight operator, if the rated capacity is greater than 100 Wh but not exceeding 160 Wh.
Powerbank Capacity Carry-on baggage Checked baggage Operator approval
<= 100 Wh Yes (max 20 ud) No No
>100 Wh to <= 160 Wh Yes (max 2 ud) No Yes
> 160 Wh Not allowed on passenger aircraft

Although these regulations govern the airlines, you can check their documentation on dangerous goods if they include other restrictions for portable chargers:

How to check if your power bank is allowed on a plane?

Typically, the power bank specification sheet usually indicates its rated capacity in Ah and Wh but if you can not find it you can always calculate it for yourself:

A power bank consists of a set of lithium-ion batteries of a certain capacity and a common voltage of 3.7V (note that it can also be at another voltage: 3.6V, 3.8V or 3.85V!)

To know the rated capacity in Watt-hour (Wh), you must multiply the power bank’s total capacity indicated in mAh by this voltage and divide it by 1000:

Rated Capacity (Wh) = (mAh x V) / 1000

You can also use our own mAh to Wh converter below:

To understand it better, let’s see some examples to know if we can bring a portable charger of different capacities on a plane:

Case study

1) If the portable charger has a capacity of 20000 mAh at a voltage of 3.7V:

Rated capacity = (20000 mAh x 3.7V) / 1000 = 74 Wh < 100 Wh βœ…

If the rated capacity is less than 100 Wh, we could carry this portable charger and up to 20 units* according to IATA Dangerous Goods Regulations. Also, no prior approval from the flight operator is required.

*However, some airlines tend to limit this number, such as Iberia Express, which reduces this number to only 4 units.

2) If the portable charger has a capacity of 30000 mAh at a voltage of 3.7V:

100 Wh < Rated capacity = 111 Wh < 160 Wh βœ…

The rated capacity is between 100 Wh and 160 Wh, therefore, we could carry up to 2 units but, in this case, prior approval by the flight operator would be required.

3) If the portable charger has a capacity of 50000 mAh at a voltage of 3.7V:

Rated capacity = 185Wh > 160 Wh ❌

In this case, the rated capacity is greater than 160 Wh, we cannot carry a 30000 mAh portable charger on a passenger aircraft.
