Carry On Rules for Phone Power Banks
Passengers can generally keep small phone power banks in their carry on luggage. Aviation security allows power banks in the cabin because they are easier to monitor and reduce fire risks compared to checked bags. You must declare larger units at the boarding gate if they require special permission.
Checked Bag Restrictions
Most airlines do not allow phone power banks in checked bags. Since lithium batteries can pose a fire hazard, keeping them in the cabin lets crew respond quickly to any issue. Always verify specific airline rules before placing a power bank in a checked suitcase.
Capacity Limits and Watt Hours
Under 100 Wh Power Banks
Power banks labeled under 100 Wh are widely accepted in carry on baggage without extra approval. These units usually support standard smartphones and smaller tablets on multiple flights.
100 to 160 Wh Power Banks
Power banks between 100 and 160 Wh may be carried only with written airline approval. Passengers typically need to request permission in advance and are often limited to two such devices per trip.
Over 160 Wh Power Banks
Units rated over 160 Wh are not permitted on commercial passenger aircraft. You should leave these high-capacity models at home or arrange specialized cargo transport if they are essential.
Airline Policy Around Phone Power Banks
Each airline can apply its own detailed rules, so it is important to review your carrier’s policy before travel. Low cost carriers, legacy airlines, and regional operators may publish slightly different limits on their websites. When in doubt, contact the airline directly to confirm what is allowed.

FAQ
Reader questions
Can I use my phone power bank during the flight to charge my phone?
You can typically use a phone power bank while in the air only when the airline allows personal electronic devices in airplane mode. Check crew announcements and seatback displays for current usage rules.
Do I need to switch off my power bank during security screening?
Yes, you should power off your phone power bank before placing it on the X‑ray belt. A powered on device can raise security concerns and may require additional screening.
Is it okay to keep a power bank in my backpack during a short domestic flight?
Yes, as long as the backpack containing the power bank stays with you as a carry on and the unit meets size and capacity limits. A small power bank under 100 Wh is usually fine for domestic trips.
What happens if my power bank is damaged or starts smoking at the airport?
Immediately notify airport staff or airline personnel. Do not attempt to handle a smoking or damaged lithium battery yourself, and follow crew instructions for emergency procedures.
