Diy Pwoerbank module question

hello guys, do you know of any good diy powerbank modules with quickcharge?
is it possible to use 2 powerbank modules for the same powerbank?
will i be able to charge the powerbank with 2 inputs without the batteries exploding?

If you find some cheap china diy module with isn’t safe, we possibly wouldn’t know.
Better stick to safe ready-to-use products like the Soshine E3S-QC:

If you’re making your own battery pack you could use something like this – https://m.ebay.com/itm/12-24V-to-QC3-0-2-0-DC-DC-Step-Down-Buck-Converte...

I have one connected to a 3s lipo for qc2 charging my phone

It’s expensive, though. You could buy a 10000mah Xiaomi POwerbank 2 or pro for ~2USD more, so even with free (already owned) 18650 cells, it’s hard to justify. It’s too bad really, it’s the only powerbank with 4x (or 3x) replaceable 18650 cells I have found that both charges and discharges at a decent rate. And using replacable 18650 is nice when you need that extra Wh once or twice a year, and have more 18650 cells lying around.
