TAGG 20000 mAh Power Bank Turbo – travel companion?

I thought these 20,000 mAH powerbanks were usually bigger? Asking because I'm a regular user of the OnePlus power bank, I think it's really compact and well designed. Sure there are many other 10,000 mAH powerbanks, but I stuck with it because of its design and its material. This is the kind of identity TAGG is trying to create as well, but in its own style. The world of mobile accessories is a tough place, so does the TAGG powerbank stand out? The powerbank is a simple device. It needs to be able to store a of power and it needs to be compact enough for travel. All the extra features are a bonus. The TAGG Power bank ticks all the basic boxes. The output is fast enough to recharge that dying smartphone, big enough to sustain it and under the allowed limit for air travel. I don't mind the micro USB but using USB C would have been future proof. Both the outs charge simultaneously as you would expect from a good powerbank. There is some light, there is some carbon fibre styling. The power bank looks really good, if you're into that sort of a thing. I'm guessing gamers would love this ...
