Thank you for the review HKJ. I looked up some data in your comparator. They are almost identical twins.

These look great. Thanks for testing them!

I see that you tested the newer Sofirn 5000mAh 21700 cells. Do you have their original 4000mAh in the lineup? Seems like they’re still supplying that one with lights and few or none of the 5000 (but they sell it separately in their ali store).

I have not tested the 4000mAh Soshine.

The best way to check if I have tested a cell is to check my website.
