Important advice issued to anyone that travels with portable charger

However, there are some things you should know before taking power banks away with you on That's because they are combustable and could potentially cause damage if you're not careful.

While frequent flyers will know it's prohibited to pack power banks into checked bags that go into the hold, they may not know there can be rules to follow when it comes to popping them in hand luggage.

So to make everything crystal clear, pilot's wife Laurie waded in with her advice. The online sensation, known as Travel Tips By Laurie on Instagram, spoke about rule changes that are being implemented by Southwest Airlines on May 28.

It's very useful information that's important to keep in mind for every flight you book - no matter the airline - as it all comes down to health and safety.

Laurie said: "Here's one new travel tip for you. All power banks are combustable. You are no longer allowed to have your power bank or portable charger or phone charger plugged into your phone in your personal item bag, under your airplane seat or in the overhead bins.

"The good news is - nobody is ever going to charge their phone in their carry on bag in the overhead bin. So, I think we're safe. It's one way to make sure they're not near other bags in the overhead bins and catch on fire for no reason.

"[Southwest Airlines] have made a rule and now we think other airlines are going to make a rule that you cannot charge your phone in the overhead bins or in your carry-on suitcase."

Another remarked: "Didn't know this!" And a third added: "I flew Southwest last weekend and learned this was a new rule. I think it's wise."

Which safety precautions should you follow when using power banks during flights?

Verify your airline's rules regarding the use and transportation of power banks. Airlines typically have size and capacity limits.

Power banks with a capacity of more than 100 Wh (watt-hours) usually require airline approval, and most airlines prohibit devices over 160 Wh.

Power banks are not allowed in checked luggage. Always carry them in your hand baggage to reduce fire risks in the cargo hold.

Choose power banks that comply with safety standards, such as UL, CE, or similar certifications. Avoid counterfeit or poorly designed power banks, as they may pose safety hazards.

Check the power bank for any visible signs of damage, swelling, or corrosion before taking them away with you. Do not bring a damaged power bank on board.

Follow instructions from the cabin crew and turn off or store power banks when prompted, especially during takeoff and landing phases.

Avoid leaving your device or power bank charging unattended to prevent overheating or potential malfunctions.

Learn how to react in case the power bank overheats, starts swelling, or leaks. Notify flight attendants immediately if you suspect an issue.
