Just wondering if there is a size/capacity limit for external power banks for carry on luggage for international travel?

 

I've previously travelled ok with 16,000 mAh to Australia and Europe, but will be transiting Air NZ through LA, so want to make sure rules have not changed or US different from rest of world.

 

I ask because salesman at Harvey Norman thought anything over 10,000mAh was at risk of confiscation?

Air NZ website lists their requirements. There is also a post on TravelTalk detailing this.

99% of airlines impose a 100Wh (watt hour) limit. Note this is Wh not mA so you'll need to refer to the Wh rating on your powerbank.

As most powerbanks are 3.8V this means your limit is around 26,800mA which is a standard size large powerbank.

Limit is 100Wh - it is not mAh.

Just realised predictive text on my phone changed mAh to mA in my post above. Limit is 26,800 mAh for a unit with 3.7V cells.

I have been travelling with my 20,000 mAh power bank for a couple of years and never had it questioned whatsoever. Went to US twice in the last six months on AA and Hawaiian flights and not even a question about the content of my bag, which was a mirrorless with a couple spare batteries, go pro with a couple spare batteries, drone with spare batteries along with the before mentioned power bank..

My batteries were checked in Toronto last August and the said there was a 26,000-ish mAh limit......and mine were 10k and 13k....so no problem. Thwey are worried about batteries bursting into flames.....and a large battery would be harder to control......

At every airport in the world it's security that always enforces restricted items. Here in NZ Avsec still confiscate hundreds of powerbanks per week across the country from people who check them into checked luggage - despite people having to actually read and agree to a statement on the Air NZ kiosk or online check-in website saying they don't have any restricted items or powerbanks!

I asked about this for checked baggage a little while ago. I was going to play a golf tournament and wondered about the practicality of taking my electric trundler. However the 380Wh battery even exceeded the allowance for those using wheelchairs so it wasn't possible.
