Jackery Bolt vs ZMI USB-C PD Backup Battery Packs (2017)

Analysis:

The Jackery Bolt 600 is one of the very best USB-C Battery Packs that one can get for around $25. The ZMI 20k Power Bank QB820, however, while a very good choice at its $55 price point, falls just short of being remarkable.

The Jackery Bolt 600 was loved by reviewers at TechGearLab, a highly trusted source that performs reliable in-depth testing. It did great in its "The Best Portable Chargers of 2020" roundup where it was named its "Top Pick", which, in itself, makes it a product worth considering.

Moving on to the ZMI 20k Power Bank QB820: no sources that perform reliable and objective hands-on testing have included it in their USB-C Battery Pack roundups, which usually means that a product doesn't make for a good purchase.

Lastly, we tried to do a direct Jackery Bolt 600 vs. ZMI 20k Power Bank QB820 comparison of review ratings between these two products, but couldn't find any review scores for the ZMI 20k Power Bank QB820.

Compared to all other USB-C Battery Packs on the market, however, the Jackery Bolt 600 performed great. When averaged out, it earned a rating of 8.5 out of 10, which is much better than the 7.8 review average of USB-C Battery Packs in general.
