Can you bring a portable power station on a plane?
Troubleshooting Updated 2026-08-01
Almost certainly not, unless it is one of the very small ones. Passenger rules for lithium batteries are written in watt-hours per battery, not in kilograms or litres: there is a threshold below which a battery travels in the cabin without asking, a band above it that needs the operator’s approval, and above that band passenger aircraft do not carry them at all. Most power stations sit far above the whole scale.
Two further points decide more cases than the number does. Spare lithium batteries — which is what a power station is — belong in carry-on and not in checked baggage. And the rule that binds you is the one your operator publishes for your flight on the day, not a figure on a website.
Policy content, and what its date means
No threshold on this page is permission to travel with anything. The rule that applies to you is the one your operating carrier publishes for your flight.
Why the limit is in watt-hours
A lithium cell that fails releases energy that was stored in it, so the quantity that predicts how bad a failure is, is stored energy — which is what a watt-hour measures. Weight is a poor proxy because chemistries differ in energy density, and volume is worse. That is why the printed limits are watt-hour figures and why the airline desk will ask for a watt-hour number rather than for a weight. If your device only shows amp-hours and a voltage, multiply them: amp-hours times volts gives watt-hours, and that is the figure to declare.
What our records publish for this
The watt-hour figure that applies to airline rules
Each station record carries the capacity figure relevant to passenger battery rules. Compare your own machine against the thresholds your carrier publishes — these are the numbers to compare, not the ones on the marketing page.
One of the smallest machines we hold, and still above the free-carry threshold.

The pattern is unambiguous: the class of product starts well above where passenger allowances end. A power bank in the low hundreds of watt-hours is a plausible travel item; a power station is not, and the honest planning assumption is that it goes by ground transport or stays home. If your trip genuinely needs one at the destination, shipping it as cargo under the applicable dangerous-goods rules is a different process with its own paperwork, and it is the one worth investigating.
Where the authoritative answer lives
Three sources, in the order they bind
These are not equivalent. The last one governs, and the first two tell you what to expect before you get there.
This is the rule that will actually be applied at your gate, and it is the operator’s to set within the international framework. Codeshare flights follow the operating carrier, not the one on your ticket. Check it for the flight you are on, close to the date.
In the United States the Federal Aviation Administration publishes a PackSafe page for batteries that states the passenger thresholds and the carry-on-only rule for spares. Other countries’ authorities publish an equivalent. This is where the numbers your carrier implements come from.
Open the source →The watt-hour thresholds carriers apply originate in the international lithium-battery provisions that the industry’s dangerous-goods regulations restate each year. Useful for understanding why the rule has the shape it does; not useful as something to show at a check-in desk.
If you are travelling with something small enough
- Carry it in the cabin. Spare lithium batteries are not accepted in checked baggage, and a power station is a spare battery regardless of what it is marketed as.
- Have the watt-hour figure visible on the device or its label. Staff will look for it, and a device that only shows amp-hours invites a conversation you can avoid.
- Protect the terminals and switch it off. Anything that could short a battery in a bag is the failure mode the rules exist to prevent.
- Ask in advance if you are anywhere near the approval band. Approval is something the operator grants beforehand, not something negotiated at the gate.
