You must pack it in carry-on luggage. The Anker Powercore sits at a 7437Wh 20100mAh1000 x 37V which means you can take it with you on a plane. They generally impose a limit on capacity per passenger and on top of this disallow checking them in so you must take them into your hand luggage.
To protect LIPO batteries in your carry-on baggage from short circuit you must pack them using any of the following methods.
Battery-powered devices must be protected from accidental activation and heat generation. Lithium-ion rechargeable batteries and portable batteries that contain them can only be packed in carry-on baggage. In the cabin airline flight crews can better monitor conditions and have access to the batteries or device if a fire does occur. You can only take batteries rated under 100Wh.
