This Folomov A4 is even better:
How low can it go, for charging smaller cells?
It can go down to 250mA.
So, like my Zanflare C4 that is still up for fale, it is decent for 10440s.
and the folomov can do slot 1 and slot 4 at 3 amps a cell…
only using those two though… anymore and it’ll drop down to 2 amps per…
Also, the folomov did not fit my 21700 …if those MAY be in you future…
$25 is a good price for these…
