Can we fly with a jetpack?
Jet packs have been developed using a variety of mechanisms, but their uses are limited because of factors including the Earth’s atmosphere, gravity, the low energy density of extreme fuels, and the human body not being suited to flight, so they are principally used for stunts. The idea of a jet pack was first hatched in 1919, about sixteen years after the first flight of the Orville Brothers, when a Russian inventor drew up a design that was never actually built. The idea then progressed in fits and starts, inching closer to a working prototype around 1960.The concept of a jetpack, or rather a rocket pack, using thrust from rocket engines was first conceived by a Russian named Alexander Andreev in 1919.

Can I fly with a power pack?
Portable chargers or power banks containing a lithium ion battery must be packed in carry-on bags. Spare lithium batteries, which include both power banks and phone chargers, are prohibited in checked luggage. For more information, see the FAA guidance on portable rechargers. Capacity Limits: Power banks with a capacity of up to 100Wh (approximately 27,000 mAh) are generally allowed in carry-on luggage without requiring any special approval. If the capacity falls between 100Wh and 160Wh, you typically need airline approval before bringing it on board.
