If you want the best capacity/volume ratio, choose AlzaPower Onyx. This has a slightly lower capacity at a higher weight. But then again it has half the charging power, passthrough and display.
35W charging, passthrough
Weight actually only 300 grams
Battery status display
It is NOT 20,000 mAh (77 Wh). It will give out about 63-64 Wh. True "20,000 mAh" power banks are capable of delivering 71-72 Wh.
