Having some extra juice for your phone, iPad or laptop is always necessary, especially when you need to go on a business trip or you have any travel plans involving a long journey or different countries. There is no doubt that a powerful portable charger is a must for your trip as more and more travel essential gadgets requiring charging.

However, some consumer power banks are not allowed to be carried on the plane for some safety transportation restrictions. What restrictions of power bank on plane should you know? What brands of power bank are allowed on airplane? Don’t worry. Be patient to read this article, you’ll know the answer.

Before your trip, knowing the following two rules will help you avoid many accidents while boarding a flight.

1. Power banks need to be stored in carry-on baggage.

This rule is simple. It’s the best way to put everything involving battery into your carry-on baggage. If you bring iPhone, Android phone, iPad or laptop that includes battery or anything else that uses a rechargeable lithium-ion battery, they should go into your carry-on. Why to do this? Because it’s really safer to keep these potentially explosive devices somewhere they can be monitored to maintain our personal and property safety. It’s so terrible and frightening that a battery catches fire to the cargo hold for no one can predict and notice a fire before it spreads, which is much worse than in the cabin.

2. Power bank must not exceed 100Wh (Watt Hours).

According to Travel Guide, the International Civil Aviation Organization's (ICAO) announced its latest instructions for the safe transportation of dangerous goods by air that power banks allowed for carry-on baggage in the aircraft cabin must not exceed 100 Wh, or equivalent to less than 27,000 mAh.

However, if you are need to bring a bigger power bank, you can bring it along with you while passing through the approval of the airline concerned. It only occurs when the capacity of battery is from 100.01 to 160 Wh. If your power bank doesn’t measure its output with Watt-Hours, you can calculate from mAh to Wh according to the formula which is (mAh)/1000*(V)=(Wh).

For example, a 26,800mAh power bank of 3.7V rating would be (26800/1000)*3.7=99.16Wh. 160Wh is equal to 43,243mAh at 3.7V. If your power bank is bigger than 160 Wh, it may cause some problems. So it has to follow the restriction on dangerous cargo.

Fortunately, it’s not common seen that a power bank is over that limit as most power packs are below 100 Wh. Anyway it’s best to check your power bank. ALL Zendure power banks are approved for air-travel.
