Flying with battery-powered medical devices from China

“Can I carry it?” and “can I use it in flight?” are separate questions. Ask every operating airline on the itinerary, especially on code-share or connecting flights. Approval by one carrier does not bind another.

Start with the battery label

The battery type must meet UN38.3 testing. Lithium-ion batteries up to 100Wh generally do not need approval solely because of capacity. Devices and spare batteries from 100Wh to 160Wh require airline approval; spare batteries above 100Wh are limited to two, must stay in the cabin and must be protected individually against short circuit. Larger batteries are normally outside passenger baggage rules.

Carriage and use are different

A device packed in checked baggage must be completely switched off and protected from activation and damage. Spare batteries remain in carry-on baggage. Continuous use of a ventilator, portable oxygen concentrator or other life-support equipment can require advance special-assistance approval even below 100Wh. CPAP, POC, ventilator, AED and compressed oxygen are not one category.

Send the operating airline this information

• make, model, medical purpose, dimensions and weight;
• battery chemistry, Wh rating, number of installed and spare batteries;
• whether it will be carried or used, and during which flight phases;
• UN38.3 test summary if the airline requests it;
• doctor’s letter and power requirements if requested.

There is no universal 72-hour deadline or universal “150% battery” rule. Airline examples differ. Obtain written approval, protect terminals and carry enough independent power for delays without relying on an aircraft socket.
