A pair LiIon 16340 cells with USB charging input

The cells matches fairly well at low current, but not as fine at higher current.


For users with only a few cells or traveling users USB charging is a very nice options. There is usually a problem with the length of especially smaller cells, but these cells are only 2mm too long, this means they will fit more equipment.

They look like good cells in this size.
