Vapcell P2150A 21700 5000mAh: An unusual cell with built-in charging and a USB power-bank function; capacity fell short, but the author found it interesting and sometimes useful.

Basen BS26003: Decent general-purpose cells, but not high-current ones; high loads cause strain and substantial voltage sag.
