When travelling, having a fully charged power bank at hand can ensure your communication devices never run out of juice. But is it safe to carry on board a flight? It's something you'll have to verify.

The International Air Transport Association (IATA) categorically states that “power banks are considered spare batteries and must be individually protected from short-circuit and carried in carry-on baggage only.” Etihad and Emirates both reiterate the same regulations, with Etihad specifying that if you are travelling with a smart bag that has an integrated power bank, it should have a watt/hour rating lower than 100Wh, otherwise you would require prior approval.

Our expert, Muhammad Usman Ilyas, assistant professor at the School of Computer Science in the University of Birmingham Dubai, explained why such rules exist: "Batteries in contemporary mobile computing devices rely on lithium-ion battery technology. For its advantage of high power density, lithium-ion batteries are susceptible to damage, causing a short-circuit, overheating and possible explosion. Limiting the size and capacity of power banks reduces the risk of a severe fire incident. Airline cabins are equipped with fire detection and suppression systems designed to handle emergencies. However, by restricting the size of power banks, the risk of a fire exceeding the capabilities of the onboard systems is minimised."

What should I look for when buying a power bank for travel?

As with power banks you'd buy for university or school work, it's important to assess various factors before buying. These include the power bank's capacity, portability, output ports, input charging, safety features and the brand's reputation.

Ilyas advised: "Opt for a compact and lightweight power bank that is easy to carry during your vacation. Look for a power bank with sufficient capacity to charge your devices multiple times. Consider the power bank's milliampere-hour (mAh) rating, which indicates its capacity - a higher mAh rating means more charging cycles." For a power bank under 100Wh, based on airline rules, the maximum mAh rating is 27,000mAh.

It's also worth considering a power bank with an adequate number of output ports so that you can charge several devices simultaneously. Ilyas added: "Look for power banks that support fast charging technologies like USB Power Delivery or Qualcomm Quick Charge to charge devices quickly." Similarly, the input port should also support fast recharging options, such as USB-C power delivery - it reduces the time it takes to get your power bank's battery back to full capacity, between uses.
