Power banks were a mistake. It's akin to carrying fireworks in your bag. Ban them all from air travel.

Every one I have owned has been recalled for being a fire hazard. EVERY SINGLE ONE. I stopped buying them as a result. We're talking name brand devices, not junk off AliExpress.

It's great technology, but sadly humans are fucking morons, and dodgy manufacturers making explosive power banks has lead to the restrictions...

Although honestly how bad is it, powerbanks are very popular, I can imagine in some regions there'd be hundreds of flights taking off daily with 150+ power banks on board (the majority of passengers on a 737), and they've all landed safely.

In my city, I could scan a QR code and pay the parking meter that way. Now they've decomissioned this and you have to go to the app and select the section of the road you're parked at. Why, because scammers made scammy QR codes. Great tech, can't have them because humanity's inherent scumbaggery.

I've never had any issues with brand name, not dollar store power banks and I've been using them for more than a decade. I'd totally expect a $5 pink power bank from a alphabet amazon seller to be an issue, but anything modern and reasonable like Anker are very unlikely to cause you any issues. Balancing, protection are very much solved issues at this point for the cell chemistries we use.

If LiPo was the issue, using LiFePo4 or LTO cells for planes would be a totally reasonable alternative too. LTO cells are so safe the manufacturer of them has videos on youtube of them hammering nails into the cells, cutting them with a saw, and crushing them with a press and they don't really care.

what about your mobile phone or laptop?

  • Phone batteries are typically smaller (less energy which can be violently dissipated) than most power banks.

    Naturally you will ask, what about tablets and laptops? They are prohibited from checked luggage for this reason. Power banks however are smaller and easier to conceal.

    The risk is really in a fire developing in your bag down below in cargo, where no one can see it. By the time the fire alarms go off, it's too late and good luck if you are over water or the Arctic. If it happens upstairs they can at least tend to it with a fire extinguisher or bag/blanket.

    See ValuJet Flight 592, fire in an airplane's cargo hold is probably one of the scariest ways to slowly die.

    It's all about corralling risk. You can't tell people they can't bring their laptops. But power banks are unnecessary nice-to-haves.
