No idea but I've never been stopped with my 20,000mAH bank, on various airlines. Easyjet, Delta, Etihad, Air China, KLM, Air France and British Airways. I'm sure there are more but these are the ones I can think of off the top of my head.

Not sure but in case you are not aware I think planes now have charging points for passengers as I read it in similar thread a week or so ago.

There are many thousands of aircraft which do not have charging facilities for passengers.

I was not saying they all had it but he could find the thread now he knows it was asked.

100wh max

I have flown hundreds of times and never had a pack checked at any airport in any country.
I carry a huge kit type, 8x18650, cell pack at the moment and no issues.

Just under the length of a snake.

1.21 gigawatts.

It's down to the airline. When I was in South-East Asia some of them had a max size limit of 27,000mAh, at least for hand luggage, and they did actually check the 20,0000mAh one I had on me going through security once or twice. I believe this is usually the standard max capacity if one is enforced.

I flew out there via Heathrow with BA and don't remember if they had a limit, but for the sake of not having to own multiple banks it's easiest just to get something in that 20-25,000 range as that'll be enough for most scenarios.

That’s the FAA limit, so you can safely assume all American airlines will follow this.

27,000mah is 100wh for a 3.7v pack.

I tried to send mine home when I did the camino walk in Spain with a bunch of other unnecessary stuff and was told. No chance, it will just be refused

Was thinking about making one of these from old laptop battery's, not sure I would make a spot welder out of a. Microwave though as some. On YouTube suggest, but the DIY ebike batterys look an interesting project

You can buy a plug and play kit from the Chinese direct purchase places.
That's what I did

That sounds easier,I know you can also solder but apparently need a top notch iron and be a very very quick to avoid damage, suppose a a battery management system needed also unless one of those complex chargers that does individually

Not had any problems with my 22'500mah pack.

Bald-Eagle22 · 27 Dec 2019 at 17:50

I’m flying with EVA Air from Heathrow to Bangkok , just looked at my power-bank and it’s 26,800 mah 3.7 volts .

Feef · 29 Dec 2019 at 00:45

Well, Eva's limit seems to be 160wh, which is apparently 42,000-odd mah at 3.7v. So should be fine.

That, and anecdotally, I don't know a any Taiwanese people who don't own several of the things, so I can't see it being a problem

Taken that flight myself before continuing to Taipei.

Courier or with your on aircraft? as there are a lot of restrictions around li-ion battery tech when it comes to shipping but less so in the cabin as a passenger.

What is actually enforced is kind of random though depending on airline and route, etc. so if travelling more generally I wouldn't assume anything beyond ~20,000mah 3.7V is OK - below that you'd have to be unlucky to have problems.
