Short answer: Yes if the laptop power bank is compliant, but laptop-class models are often close to 100 Wh or above it. In 2026, plan for carry-on only, no more than two lithium-ion power banks, 100 Wh or less for ordinary passenger travel, no recharging the power bank from aircraft power, and airline-specific review for any model above 100 Wh.
A power bank marketed for laptops is still a standalone power bank. High USB-C wattage, “laptop charger” branding, or built-in cables do not create a separate exemption from lithium-battery aviation rules.
The important number is watt-hours, not output watts. A 145 W or 200 W output rating describes how fast the pack can charge a laptop; the flight limit depends on the stored battery energy in Wh.
Many laptop-class packs sit near the 100 Wh line, and some 30,000 mAh models are around 111 Wh. Under the 2026 passenger-facing guidance, ordinary power-bank travel should be planned around two units not exceeding 100 Wh, while over-100Wh cases need airline- and route-specific review.
Rule summary
- Device type
- Laptop power banks are still standalone lithium-ion power banks.
- Key number
- Use Wh for flight limits; output watts are not the capacity limit.
- <= 100 Wh
- Ordinary 2026 passenger power-bank band, still subject to route and airline checks.
- > 100 Wh
- Do not assume allowed; check airline approval and trip-specific rules before travel.

The final answer can change by model, airline, country, certification mark, label evidence, and recall status.

Does a 100W USB-C power bank mean 100 Wh?
No. 100 W is output power, while 100 Wh is stored energy. A laptop power bank can output 100 W and still be below, near, or above 100 Wh depending on its cells.
Can I bring a 145W laptop power bank on a plane?
Maybe. Check the Wh rating. For example, some 145 W laptop-class packs are around 90 Wh, while other large packs can exceed 100 Wh and need airline-specific review.
Can I charge my laptop from a power bank during the flight?
It depends on airline policy and crew instructions. The clear 2026 rule is that you must not recharge the power bank itself from aircraft power during flight.
Can a laptop power bank go in checked baggage?
No. A standalone laptop power bank is a spare lithium battery and should travel in carry-on baggage only.
