So what’s the problem with devices containing lithium-ion batteries? Faulty lithium-ion batteries can overheat or short-circuit, triggering a dangerous chain reaction called thermal runaway, in which the rising temperature inside the battery continually releases energy as it gets hotter and hotter. This increases the risk of fire, but the materials are also very reactive and flammable. Lithium fires are aggressive and self-sustaining. Efforts to put them out are likely to fail, and if successful, the fire may reignite. As reported by CBS News, an Alaska Airlines flight had to land after an external battery on board caught fire. While not on board a plane, in another incident, a 75-year-old woman died from her injuries after a magazine exploded in her lap.

The simplest ways to limit your exposure to a lithium battery fire are to avoid cheap, poorly made devices and to follow the manufacturer’s recommendations for proper use. Overheating and other complications can occur when batteries are overused, such as when too many devices are plugged in simultaneously. Problems can also arise when lithium devices are improperly handled, damaged, or stored incorrectly.
Always store batteries away from anything flammable or that could damage the device or battery. Store them at temperatures above 32 degrees Fahrenheit (0 degrees Celsius) and below 105 degrees Fahrenheit (40 degrees Celsius). Also, try to avoid exposing them to extreme temperatures when traveling.
When boarding a plane, follow all safety instructions, which usually include information about devices containing lithium batteries — these devices should never be left in checked baggage. Following TSA carry-on battery restrictions is a great way to stay safe everywhere, not just at the airport or on a plane. Additionally, the best TSA-approved power banks on Amazon not only meet allowance requirements but are also generally well-received and considered safe by many users.
