Airline passengers are being warned not to pack power banks in their hold luggage ahead of the summer holiday travel period.

Devices with rechargeable batteries, like mobile phones, laptops, tablets, and smartwatches can be plugged into power banks on the go, where charging sockets may not be available. However, power banks are not danger-free or environmentally friendly.
