Spare (uninstalled) lithium ion and lithium metal batteries, including power banks and cell phone battery charging cases, must be carried in carry-on baggage only. When a carry-on bag is checked at the gate or at planeside, all spare lithium batteries and power banks must be removed from the bag and kept with the passenger in the aircraft cabin.
Lithium-ion batteries, such as power banks, should only be packed in carry-on baggage, according to US FAA and Transportation Security Administration (TSA) rules. In general, most airlines allow each passenger to carry a maximum of two lithium-ion power banks of 100-160 Watt-hour (Wh) into the cabin.
Power banks and batteries are now only allowed in hand luggage, not overhead bins. Passengers are also prohibited to charge their power banks by plugging them to in-seat power supply systems that airlines provide, the report says.
Similarly, passengers are not allowed to recharge the power bank from an aircraft’s USB outlet. Some airlines are requiring passengers to remove their power banks from bags and keep them in a seat pocket. They also advise insulating the terminals to avoid a short circuit. Why are airlines banning power banks now?

Zinc bromine flow batteries are a promising energy storage technology with a number of advantages over other types of batteries. This article provides a comprehensive overview of ZBRFBs, including their working principles, advantages, disadvantages, and applications.
A zinc-bromine battery is a rechargeable battery system that uses the reaction between zinc metal and bromine to produce electric current, with an electrolyte composed of an aqueous solution of zinc bromide. Zinc has long been used as the negative electrode of primary cells. It is a widely available, relatively inexpensive metal.
Zinc-bromine flow batteries (ZBFBs) are promising candidates for the large-scale stationary energy storage application due to their inherent scalability and flexibility, low cost, green, and environmentally friendly characteristics.
Zinc–bromine batteries can be split into two groups: flow batteries and non-flow batteries. There are no longer any companies commercializing flow batteries, Gelion (Australia) have non-flow technology that they are developing and EOS Energy Enterprises (US) are commercializing their non-flow system.
With a zero-tariff system fundamentally in place after the independent customs operation, high-quality global resources can flow into Hainan with greater freedom and efficiency, Wu said. Trade liberalization and facilitation are defining features of a free trade port.
On June 10, 2021, the 29th meeting of the Standing Committee of the 13th National People's Congress passed the Hainan Free Trade Port Law of the People's Republic of China, which determined to establish and improve the Hainan Free Trade Port customs supervision special zone system with closed-off customs operations on the entire island.
In April 2018, China announced a decision to develop Hainan into a pilot free-trade zone while gradually exploring and steadily promoting the establishment of an FTP with Chinese characteristics. In June 2020, a master plan was unveiled to build the island into a globally influential and high-level FTP by the middle of the century.
BEIJING, Aug. 8 -- China's Hainan Free Trade Port (FTP) is set to launch an island-wide independent customs operation on Dec. 18, 2025, underscoring the country's wider push for high-standard opening up.
