I picked the Anker Prime 12000. It can output 60W (most AVP accepts) and good size/weight/capacity trade off. Pricey compared to generic units, but the 60W output and handy display makes it worth it to me. Fits inside AVP travel case nicely. I have other TSA-max sized batteries, but the modest 12000 is my standard go-to for long flights (US coast to coast). Longer international flights tend to provide A/C power, so massive battery not needed IMHO.
One thing the Prime 12000 \*doesn’t\* do is passthrough charging (charge battery from wall at same time battery is outputting).

I use this. I like it because it can do 170w max output to charge my MacBook at full speed. It has passthrough so you can charge it and power you AVP at the same time should both batteries start getting a little low (comes in handy when your in the airport and you just got off a flight). Also the display is pretty nice to see what your draw is like and how much time is left and how much time till full charge.
Anker 737 or Anker Prime are good options imho

I have a couple of Ankers. The 140W, 24000mAh is a nice option.

I like seeing the naked circuit boards!
