Portable battery for recharging

[Michael CM1]

I have to replace a portable battery pack that was stolen from me along with other things (including a MBP and iPad). The previous battery pack I had was an Anker 20,000 mAh model that I got because it would charge my MacBook Pro -- not quickly, but it basically would keep it from losing charge when on and recharge it slowly when the computer wasn't active.

So here's what I'm looking at getting now: https://www.amazon.com/gp/product/B07DDD2HLK/ref=ox_sc_act_title_11?smid=A294P4X9EWVXLJ&psc=1

I wanted to make sure I was getting something that would recharge this thing. Honestly I mostly would use this battery pack for recharging an iPhone 7 Plus or iPad, but I got that capacity before because it's about what a MacBook Pro battery is. Having that battery keeps me from needing to carry around the charging brick if I'm just going somewhere for day.

I did a good bit of research before on Anker's different battery packs, but I can't really recall what I found that made me think "oh this model is much better for charging something so big compared to this other one with the same capacity." SO if someone knows of a certain feature on these batteries that makes them better for a MacBook Pro, I'd appreciate the advice. Caveat: I don't want to buy the $100 versions.
