ZMI USB-C PD Backup Battery Packs (2017) vs ZMI PowerPack Ambi 10K Dual USB-C Power Bank

Analysis:

The ZMI 20k Power Bank QB820 is a great USB-C Battery Pack for its $68 asking price.

The ZMI PowerPack Ambi 10K Dual USB-C Power Bank, however, while a reasonable product for $28, doesn't stack up against its competitors quite as well. If you're considering USB-C Battery Packs in the $25 range, you might want to check out some better options.

No sources that do their own in-depth testing have considered the ZMI 20k Power Bank QB820 to be a good enough purchase for it to earn a sport in their USB-C Battery Pack roundups, which is typically a bad sign.

Taking a look at the ZMI PowerPack Ambi 10K Dual USB-C Power Bank, it got featured in roundups from two reliable sources that conduct their own testing - Wirecutter (NYTimes) and Wirecutter - but it fell short of earning a top spot in either.

We also wanted to do a direct ZMI 20k Power Bank QB820 vs. ZMI PowerPack Ambi 10K Dual USB-C Power Bank review performance comparison, but we, unfortunately, weren't able to find any ZMI 20k Power Bank QB820 review scores.

Finally, we compared the ZMI PowerPack Ambi 10K Dual USB-C Power Bank to other USB-C Battery Packs on the market and found that it did much better than its competitors - its review average of 9.2 out of 10 points is considerably higher than the 7.8 review average of USB-C Battery Packs in general.
