I purchased this one from Amazon and it fast charges mine beautifully. Not sure about the 3.0, though. Sorry.
If you need ~20000 mAh, then:

Yes, the Aukey one is only QC2.0 but it still not the worst charging speeds. You'll also save >$10. The RAVPower one you linked is also just as good. Just choose based on price and features.
