Travelling with a Power Bank: The Rules and the Right Size

Airlines allow most power banks in the cabin, but not all. What to pack and what to leave.

Start with what you actually use

Before comparing models, write down the three things you will do with it every week. Most people pay for features they never open, and miss the one detail that makes daily use pleasant.

1. Check which ports and standards your devices already have.
2. Decide where it will live: the desk, the bag or the living room.
3. Set a budget, then look one step above it for build quality.

What the numbers mean

Watts tell you how fast something charges, lumens how bright a picture is, and milliamp-hours how much a battery holds. Compare like with like.

The best gadget is the one you stop noticing: it just works, every day.

Our advice

Buy from a shop that tests what it sells and answers the phone. A two-year warranty is worth more than one extra feature.
