For Philippine Airlines and Cebu Pacific, the safest common rule is to carry no more than two power banks, each rated at 100 watt-hours or less, in hand-carry baggage only. Keep them accessible, protect them from short circuits, and never place them in checked baggage.
Check watt-hours, not only milliamp-hours
Airline limits are stated in watt-hours (Wh). Use the rating printed by the manufacturer. If only mAh and nominal battery voltage are shown, calculate Wh = mAh × V ÷ 1000. For example, 20,000 mAh at a nominal 3.7 V is 74 Wh.
Do not use the USB output voltage printed beside a port if the label separately gives the battery’s nominal voltage. If the rating is missing, unreadable, altered, or inconsistent, the airline or security staff may refuse the power bank.
Keep power banks out of checked baggage
IATA classifies power banks as spare lithium batteries and says they must not be placed in checked baggage. If a cabin bag is taken at the gate and moved to the hold, remove the power bank first. Keep it in a protective pouch where it cannot be crushed or accidentally activated.
Protect exposed terminals from short circuits. Do not travel with a swollen, cracked, leaking, recalled, unusually hot, or visibly damaged unit. Tell cabin crew immediately if a power bank becomes hot, emits smoke, smells unusual, or changes shape.
Philippine Airlines limits
PAL’s current restricted-items page allows a maximum of two power banks below 100 Wh. It says they must not go in an overhead bin and should stay on your person, under the seat, or in the seat pocket. Recharging a power bank during the flight is prohibited.
PAL says a power bank may charge a personal device except during taxi, takeoff, and landing. Follow crew instructions, because an aircraft, route, or safety situation may require a stricter rule.
Cebu Pacific limits
Cebu Pacific’s current guidance also allows a maximum of two power banks, each no more than 100 Wh, as hand carry. Its power-bank page says units over 100 Wh are prohibited and power banks may not be used in flight.
That is stricter than the general rule some travellers remember for 100–160 Wh batteries. Do not assume prior airline approval will make an oversized power bank acceptable on Cebu Pacific; follow the operating airline’s current power-bank rule.
Connecting flights may use different rules
A codeshare or connecting trip can involve more than one operating airline. Follow the strictest rule across the itinerary and check each carrier. IATA’s 2026 passenger guidance notes that airlines may impose stricter conditions than the general framework.
Do not rely on a social-media comment or an old screenshot. Save the current official policy page and contact the airline before travel if the label, capacity, medical need, or connection makes the answer unclear.
Pack and inspect the unit before leaving home
Charge the power bank at home, unplug it, and check for heat or swelling. Put it in a separate protective pouch, not loose with coins, keys, or metal tools. Keep the capacity label visible and make sure you can remove it quickly if a gate agent checks the bag.
If it behaves poorly before travel, do not take it. Use the power-bank charging checks at home and replace a damaged unit through an authorised seller or recycling channel rather than experimenting at the airport.
What to confirm on travel day
Confirm the number of units, Wh limit, storage location, onboard-use rule, and whether your cabin bag could be gate-checked. Ask about the operating airline, not only the ticket seller. Crew instructions on the day take priority over general web guidance.
