When traveling by plane can bring mobile power supply

One, the passengers or crew members are for personal use containing lithium or lithium ion battery core or battery portable electronic devices (watches, calculators, cameras, mobile phones, laptops, camcorders, etc.) should carry board as hand luggage, and lithium metal battery lithium content must not exceed 2 grams, rated power of the lithium ion battery must not exceed 100 wh (watt hour). More than 100 wh but not more than 160 wh, after approved by the airlines could fit in the device or carry-on baggage. More than 160 wh lithium batteries are prohibited.

Second, the portable electronic device spare battery protection must be made in a single case of short circuit (in the original retail packaging or in other ways, electrode, insulation exposed electrode with adhesive tape, for example, or to each cell in a single plastic bag or protective box), and can only carry in hand luggage, approved by the airlines, 100-160 wh spare lithium batteries can only carry two.

Three, passengers and crew members carry lithium-ion battery powered wheelchairs or other similar transport and carry passengers for medical use containing lithium metal or lithium ion battery core or battery, portable medical electronic devices must be in accordance with the international civil aviation organization "air transport dangerous goods safety technology conditions of transportation and packing requirements and approved by the airline.

Four, the calculation method of lithium battery energy rating: rated power unit for watt hour Wh, computing method is the battery core or the capacity of the battery (Ah ampere hour as the unit) multiplied by the nominal voltage (V V) for the unit. Example: some brand mobile phone lithium battery rated capacity is 1650 mah, the nominal voltage of 3.8 V, the rated power is 1.65 * 3.8 = 6.7 Wh.
