Analysis:

No sources that do their own in-depth testing have considered the Tronsmart Presto 10400mAh USB-C to be a good enough purchase for it to earn a sport in their Portable Laptop Charger roundups, which is typically a bad sign.

As for the ZMI 20k Power Bank QB820 - it wasn't considered to be a good enough purchase to earn a spot in any roundups conducted by sources that perform objective hands-on testing, which typically indicates that a product isn't worth its asking price.

As a last step, we wanted to do a head-to-head Tronsmart Presto 10400mAh USB-C vs. ZMI 20k Power Bank QB820 comparison of their review performance but, unfortunately, weren't able to find any review ratings on either product.
