Why Some Airlines Restrict Using a Power Bank In-Flight?
Why Some Airlines Restrict Using a Power Bank In-Flight?
1. Risk of Fire
• Power banks use lithium-ion batteries, which can overheat, catch fire, or even explode if damaged or short-circuited.
2. Battery Safety
• Just like laptops and phones, lithium-ion batteries are sensitive. Continuous charging and discharging at high altitude increases the risk of malfunction if not handled properly.
3. Interference Concerns (rare but considered)
• Older guidelines suggested that uncertified or poorly made power banks might interfere with aircraft electronics. While rare, this remains a factor in airline safety policies.
4. Practical Safety Rules
• Many airlines do allow power banks, but with restrictions:
• Do not use them during taxi, takeoff, or landing.
• Keep the power bank visible (not in pockets or bags) so cabin crew can quickly respond if it overheats.
Just to be clear: Bringing a power bank is allowed in cabin luggage (not in checked baggage). What’s restricted is the usage during flight, to prevent potential emergencies.
FAQs
Can I bring a power bank on a plane?
Yes, but only in your carry-on bag, not in checked baggage.
Is there a size limit for power banks?
Yes, up to 100Wh (around 10,000mAh) is allowed freely. Between 100–160Wh (approx. 27,000–43,000mAh) may need airline approval. Above 160Wh is not allowed.
Why are power banks not allowed in checked baggage?
Because lithium-ion batteries can overheat or catch fire, and it’s safer to keep them in the cabin where crew can react quickly.
Can I carry multiple power banks?
Yes, but most airlines limit it to 2 power banks within the allowed capacity. Always check your airline’s exact rule.
