Actually, the rating from Wh which has been determined by Kemenhub is at the back of the power bank device. But not infrequently also the power bank producers do not list how big Wh is in their device.
On this occasion, Okezone helps you to find out if your power bank can be taken up into the cabin of an airplane or not. How to calculate it is quite easy.
First of all, find out how much mAh is from your powerbank. For example, a powerbank with a battery capacity of 10,000 mAh.
After that, look for the voltage rating of your powerbank. Typically, a powerbank is present in a voltage rating of 3.8V or 5V. Suppose that your powerbank shows a 5V rating.
After getting this data, you just put it in the formula. However, before entering the formula, we must first convert the mAh unit to Ah, by dividing it by 1,000 (from Mega Ampere to Ampere).
Thus, 10,000 mAh: 1000, becomes 10 Ah. This is what we will put into the formula.
For the formula itself is very simple. You just multiply the voltage with the battery capacity with the unit Ah. When entering an existing number, the formula becomes: 10 Ah x 5V = 50Wh.
If you look at this formula, then the maximum amount of capacity that can be brought to the top of the cabin is a 32,000mAh powerbank with a voltage of 5V or 42,000 mAh with a voltage of 3.8V.
In this circular, Kemenhub also prohibits the use of powerbank when the flight is done. This is to avoid the things that are not desirable during the flight.
But please note, the Soekarno Hatta Airport explains if they only allow powerbank with 100Wh who can ride the cabin without having any special treatment. But if users want to bring more than 100Wh power bank, they should consult with the airlines.
As for powerbank that exceed 160Wh, it is not allowed to climb into the cabin.
