Is 30000mah power bank allowed in flight UK?

Ugh, the Great Power Bank Predicament of 2024 (or whenever you’re reading this)!

So, I’m about to fly from the UK, and this 30,000mAh power bank is causing me more stress than the actual flight itself. Let’s be honest, we’ve all been there. You meticulously pack, check the weather, download your podcasts – then BAM! – the power bank conundrum hits you like a ton of bricks.

My gut feeling? It’s probably too big. Most airlines have a pretty strict 100Wh (watt-hour) limit for portable power banks carried in hand luggage. And you know what? I’m pretty sure my 30,000mAh beast is way, way over that.

The maths, as I understand it (and please, correct me if I’m wrong, fellow tech-savvy travellers!), is this: We need to convert milliamp-hours (mAh) to watt-hours (Wh). The calculation is supposedly straightforward: mAh x Voltage (V) / 1000 = Wh.

Now, most power banks operate at around 3.7V. Let’s do the math for my behemoth: 30,000mAh x 3.7V / 1000 = 111Wh.

PHEW! Okay, so it’s under the often-quoted 100Wh limit I thought applied. But wait… that’s not quite the whole story.

The devil, as always, is in the detail. While 100Wh is a common guideline, it’s not universally set in stone. Airlines can and do have their own interpretations and safety regulations. Plus, the actual voltage of my power bank might slightly vary from the nominal 3.7V. A higher voltage would push it over the 100Wh limit, and even a 111Wh power bank could be flagged as exceeding the limit by a certain percentage. It’s far from a straightforward yes or no answer.

So, what’s a stressed-out traveller to do?

• Check with your specific airline: This is crucial. Their website should have clear information on allowed power banks. Don’t rely on general advice; contact them directly to avoid a nasty surprise at the gate. I know, it’s a pain, but it’s better than having your power bank confiscated (and losing all that carefully-charged power!).
• Consider a smaller power bank: If I had to do this again, I’d invest in a smaller, lighter, and more airline-friendly power bank for future trips. It might seem inconvenient, but it’s much less stressful in the long run.
• Declare it: If your power bank does exceed the limit, you might need to declare it to the airline. They may require you to transport it in checked baggage, which isn’t ideal, but it might be the only option. Again, check directly with your airline on their specific policies.

This whole power bank debacle has taught me a valuable lesson: Always check airline regulations before you pack! It’s a small step that can save you a whole heap of hassle and potential heartache – trust me. I’m off to contact my airline now. Wish me luck!
