Flying with your huxi: the 2026 battery rules, explained
The short version
The aviation battery rules changed on 27 March 2026. Your huxi is fine. Here is why, with the arithmetic.
What changed
On 27 March 2026, new international rules on lithium batteries came into effect — an addendum to the ICAO Technical Instructions, since adopted into airline policy worldwide and published by the UK Civil Aviation Authority. The changes tighten the rules on power banks: a maximum of two per passenger, no recharging on board, cabin baggage only.
A huxi is not a power bank. It is a sealed device with an installed rechargeable battery — the same category as an electric toothbrush or a pair of wireless headphones. For that category, the rule is unchanged and generous: devices with lithium-ion batteries rated under 100 watt-hours travel freely in cabin baggage. No approval, no declaration, no limit of two.
The arithmetic
The allowance is 100Wh per device. Here is every huxi against it.
| Product | Battery rating | Share of the allowance |
|---|---|---|
| Thunder & Lightning | 2.5 Wh | 2.5% |
| Kur’s Egg | 2.5 Wh | 2.5% |
| Leda The Swan | 2.5 Wh | 2.5% |
| Flick | 2.2 Wh | 2.2% |
| Multi-Mini | 1.3 Wh | 1.3% |
| Sucking Sweet | 1.3 Wh | 1.3% |
| Love Loop | 1.3 Wh | 1.3% |
| One Hot Bunny | 0.85 Wh | 0.85% |
Our largest battery is under the limit by a factor of forty. You could, in principle, fly with forty of them. We recommend one.
How to pack it
Follow the guidance the airlines follow — IATA’s advice for passengers travelling with lithium batteries:
- Cabin bag, not hold luggage. Battery devices belong where the crew can reach them. This is the rule for power banks and spares, and it is good practice for everything with a battery in it.
- Fully off. Not standby. Off.
- Packed so buttons can’t press. IATA calls this preventing unintentional activation. Pack your huxi so nothing in your bag can hold a button down — its case, a sock, the middle of your clothes. This is the entire skill.
- No charging on board. The new rules prohibit recharging power banks in flight. Your huxi holds its charge for the length of any flight you can book. Charge it at the hotel.
At security
Nothing is required of you. A huxi in a scanner tray is a matte object with no cables attached. Security officers are professionals who have seen everything; you will not be the most interesting tray of their morning. If asked, the answer is “it’s a personal device” — which is true, complete, and the end of the conversation.
Questions people actually ask
Can I take my huxi on a plane?
Yes. In your cabin bag, switched fully off, packed so it can’t switch itself on.
Does it count against the two-power-bank limit?
No. The two-device limit applies to power banks. A huxi is a device with an installed battery, not a power bank.
Can it go in hold luggage?
Put it in your cabin bag. Rules for devices in checked baggage vary by airline and require the device to be completely off and protected — the cabin is simpler and safer.
Do I need to declare it?
No. Devices under 100Wh need no airline approval and no declaration.
What’s the battery rating of my huxi?
See the table above. Every huxi is rated between 0.85Wh and 2.5Wh — between 0.85% and 2.5% of the allowance.
huxi products contain sealed lithium-ion batteries rated 0.85–2.5Wh, within the 100Wh cabin allowance under the ICAO Technical Instructions (2025–2026 edition, as amended 27 March 2026).
