Shouldn't be a problem... put them seperately in few checked in luggage bag

i dont think theres a quota on how many power banks you can bring , all i know is airlines normally have quota on how heavy your stuff are , hope it helps

My in-laws were told to unload their powerbank from their luggage and bring with them into the cabin. Flight is Shanghai to Kuala Lumpur. Airasia.

TS.. custom might ask u why u bring lots of powerbank
happened to a friend of mine

only 2 are permitted if u china custom block u for carry in luggage. if u put inside another lugagge, it is prohibited.

Wonder has TS successfully return with the power bank??

Tragedy mh370 will happen again.

though i successfully bypass with 4 powerbank, my brother is unlucky, he got notice by strict woman custom personel and only able to bring home 2 only, he carry around 14 powerbank at the time.

no , all in hand carry

dont put in check in luggage..carry it with you..and make sure every power bank out in a plastic bag..

More info here 

hand carry should be okie..for me i throw the box away, then each of them put in a different plastic bag to avoid electronic disturbance..but when pass by their security check point they will ask you to take out all your electronic devices..i bought back 10k mah and a lady in front of me got a very tiny powerbank..the security check the code stated on the pwerbank and inform the girl that this they will check in for her, while mine got no problem..

just back from china with 5powerbank and 2handphone by hand carry, china immigration record down my passport and let me got without take any of my belonging...
just make sure your powerbank has the KW, V, A and made from where information. then u will safe

the last time I recalled (Feb 2014), you are not allowed to bring any battery-contained units (laptop, cellphone, tablets, or even calculators!) into your luggage. if you still wanna bring it inside luggage, take out battery form your device, buy new one in Malaysia instead.

but you can bring max 2 identical units in your hand carry with unlimited type of units.

if they detect battery unit inside your luggage, you won't able to check-in but will be called to get back your luggage. most of the time when that happen you end up lose the flight. this was told by my friend who travel countless time to China.

Eastern steel ?

can't carry with u, and they will ask u to open ur lugguage and check the battery
