Are Power Banks allowed on planes?

Answer A: It will depend on the capacity in Wh (watt hours) but most commercially available ones should be OK. The IATA guidelines say that under 100Wh (multiply Ah x V to get Wh) is OK to bring on board and in cargo if installed in equipment. If they are loose spare batteries you can bring as many in carry on but not in the hold. Between 100-160Wh same applies but you are restricted to 2 spare loose batteries and again not allowed to check in. If over 160Wh you have to declare it and it has to be packed in cargo under the Dangerous Goods guidelines.Most airlines follow the IATA guidelines.

Answer B: only restriction I found was that the battery must be under 100Wh. Keep in mind that you have to validate the rules for any Airlines you will be flying and the airport rules if they are not in the US. It must be in hand luggage and not in a suitcase in the hold.

Answer C: They may be found in (at least) IATA documentation and also a number of courier companies and most battery manufacturers have advice documents. Removable batteries must be carried in carry-on luggage with the exception mentioned below. Having batteries in carry=on makes sense – would you rather have a fire in a cargo hold or an overhead locker. There is an upper limit to the amount of Lithium metal that may be carried. Some manufacturers provide specific mass of Li per battery. Otherwise they have a linear conversion between Watt hour of battery (Vbat x mAh.) and Li metal.

Answer D: It’s fine in your carry on-luggage only. Batteries are not allowed in check-in luggage, only in carry on-luggage where they can be monitored. Here are the rules for batteries:

In order to ensure air transport safety, FAA,IATA, Airport has issued relevant regulations to regulate air passengers and crew members carrying power banks on to flights. The rated energy of power banks which can be carried on board is restricted and identification method for rated power has also been specified. For details, see the “Announcement of Rules for Air Passengers Carrying Power Bank onto Flights”.

Summary: If you want take a power bank onto a plane you should follow below instructions of security staff during the security check.  Here is the Rules in china:

“Announcement of Rules for Air Passengers Carrying Power Bank onto Flights”

1. Power bank must be carried for personal use.
2. Power bank must only be carried in hand luggage or carried around. It is not allowed to carry power banks in checked luggage.
3. If the rated power is less than 100WH, power banks can be carried without approval; power banks with the power between 100WH and 160WH can be carried after approval of air carrier. However, each passenger is only allowed to carry no more than two power banks.
4. It is not allowed to carry the power banks with power higher than 160WH or the power banks without identified rated power and with rated power unable to be worked out with the marked parameters.
5. Passengers are not allowed to use power banks to charge electronic devices during the course of the flight. Power banks must be switched “Off” during the course of the flight. Above mentioned regulations are also applicable for crew members. This announcement shall take effect from the date of its promulgation. Attachment: Calculation methods for the rated power of power banks.

Calculation methods for the rated power of power banks
If the rated power is not directly marked, the calculation methods are as follows:
1. If Nominal Voltage (V) and Nominal Capacity (Ah) are given, the rated power can be calculated as follows:
Wh=V×Ah
Nominal Voltage and Nominal Capacity are usually marked on power banks.
2. If only milliampere (mAh) is given, please divide the number by 1,000, and you get ampere-hour (Ah).
For example: Nominal Voltage is 3.7 and Nominal Capacity is 760mAh, and then you get the rated power:
760 mAh÷ 1000 = 0.76Ah
3.7V×0.76Ah=2.9Wh

Tips Before You Travel to China

What should I do before travel to China?

1. Bring all the necessary documents you need to travel in China.

Don’t forget your passport with all necessary visas, and your international airline tickets.

2. Carry your passport with you at all times.

It’s required by Chinese law. Keep a photocopy on hand, too, in case the original gets lost. Or, upload a scan to a place you can access.

3. Arrive prepared in China.

Though there is shopping on every street corner, many of the things you may be used to may be unavailable to you in China. Bring toilet paper as most restrooms will not provide it. Plan ahead by saving leftover partial rolls of toilet paper, in advance of the trip. Each time you have a partial roll left, place this in a baggie and toss it into your suitcase. Six to eight small rolls will last a family of four through a two week trip. Five-star hotels will always have western-style toilets and toilet paper. Most larger airports will have at least one western toilet in the lavatory as well. Take only a key to your house or a car key with you. Leave all others at home.
•You need your own toilet paper, especially if you are traveling by train.
•These toilets are only available in the ‘country-side’, not in the metropolitan areas in China.
•You can buy toilet paper in China. It’s not expensive.

4. Bring Pepto Bismol and Immodium chewables.

Water quality in China is very poor and you may develop slight intestinal problems if you use tap water to brush your teeth, or if you eat vegetables which have not been cooked after having been rinsed in tap water. Chew two Pepto Bismol tablets before your meal to help prevent intestinal troubles.
•Again, only in the country-side places, not in the ‘metropolitan’ areas.

5. Bring any other medications you may need on your trip as well.

6. Bring clothes according to the season when you are traveling.

China gets hotand rainy in the summer, and very cold in the winter. Bring plenty of clothes, but remember you can always find a laundromat to get your clothes washed, or use the laundry service at your hotel. Beware, however, some laundry places use detergent that can irritate sensitive skin. Having your clothing dry-cleaned instead will avoid this problem.

7. Dress the part.

The standard dress for most places in China would best be described as “smart casual.” If your tour involves some formal occasions, bring along a formal suit or dress, too.

•China is somewhat like the USA. Summer in the south is very hot and humid, and winter in the north is cold and dry.

8. Be careful not to get any water in your mouth when you shower.

It tastes normal, but could easily make you sick. Always brush your teeth with bottled water.
•In small cities, bottled water that was filtered with cheap nylon filters is still being sold. Buy name brand bottled water in big supermarkets.

9. Consult your physician(s) or a travel clinic in advance of travel.

Your doctor or health-care provider will determine what vaccinations you will need, depending on factors such as your health and immunization history, areas of the country you will be visiting, and planned activities. Be sure to have your prescriptions filled before your trip. China requires that you present a letter from your doctor indicating the need for the use of any psychotropic medicines you might be taking. Bring antibiotics and any other prescriptions you will have to take during your travel. Count enough for your days of travel, plus a few spare pills. Bring all of this in the original prescription container. The Centers for Disease Control also keep an updated page on health information for travelers to China.

10. Write the contact information for each of your doctors on an index card.

Take this with you during your day trips in case you have a medical problem, and need to call home.

11. Stock a hip pack for each member of your party with a small roll of toilet paper, and a small bottle of hand sanitizer.

Non-alcohol hand sanitizer or wipes are best, as Chinese airport security will occasionally confiscate alcohol-based sanitizers (especially in Guangzhou). Enclose also a granola bar, some cough drops, and some gum, if you’d like. These will come in handy as you travel around town. Include a flashlight since electrical blackouts can happen at any time, and you might find yourself in a dark room.
• Remember that you are in China and not anywhere else! In bathrooms in China, to reduce the amount of waste used in the area there will most likely be no toilet paper so carry around lots of tissues. Tissues can also be found in local markets for only about 1-2 Yuan.

12. Take traveler’s checks, and some cash, as credit cards are not accepted by many restaurants and shops.

Bring a security pack or money belt which will allow you to keep any return flight or train tickets and your traveler’s checks, credit cards, and or cash, safely attached to your person, underneath your clothes. This way you can keep essential items safe if there is no safe in your hotel room.
• The major banks in big and medium size cities have ATM that accept foreign ATM debit cards.
•In small cities, some banks would not even exchange your USD for RMB.

13. Other things you may need: deodorant (cant be found even in big cities), raincoat and/or umbrella, hat, sunglasses & sunscreen (depending on the season and your destination), insect repellent, converter (power adapter) if you have one or if it’s necessary for you to have one. If you are a woman, bring your own feminine hygiene products.
