Hello /diy/ i'm planning to make a few custom power banks. I want them to be as small as possible. Can someone guide me where to find most reliable circuit boards? I don't mind the price, but the only place to buy them from looks like Aliexpress or other Chinese stores. Not that i think that they sell crap but its hard to trust reviews posted there. I'm planning to use single protected 18650 battery for each one. Maybe someone knows reliable manufacturers or ect?
Thanks in advance.
Tell me why
Buying an 18650 based powerbank will be cheaper, safer and more reliable than anything you could bodge together yourself.
It will also be smaller than anything you can throw together.
Nobody will suck ya dick because you went through the trouble of making your own.
(Not that you could do that anyway, since you're here asking dumb questions)
1/10 made me reply.
>tl;dr: don't make shit that's cheaper to buy
>someone wants to make his own power bank
>hurrdurr you can just buy it cheaper
that literally applies to almost anything on this board.
Just get out or stop giving shitty useless 'advice'.
all I'm saying is spend your time and energy on something that's actually worthwhile /DIY/ing...
That way you could actually make something cool or interesting.
Anyway cockfag, adafruit has the highest quality USB boosters and Li-ion chargers for DIYing
ofc i could buy complete unit and just make new case, but i want to have a good battery and board not paying for the brand name.
>Nobody will suck ya dick because you went through the trouble of making your own.
This is where you fail miserably. I get my dick sucked all the time because i can make my own shit. Real women love men who can craft stuff. Im not planning to make the board myself. I have made one working charger already (you should be a retard not to be able to solider few wires together imo). But its voltage ripples like shit under load with the pcb i bought.
Decent charger circuts are hard to find.
Thanks for the advice tho. Sorry if i hurt your feelings, i just thought this is a good board to ask for such advice.
I am not even OP, look at the top right.
And who are you to judge that this is a 'cool' and 'approved' project and worth /diy/ing? If OP thinks it is cool and interesting, that is perfectly fine.
Stop acting like hitler, faggot.
Unless you're just doing it to learn the underlying tech, its more efficient to buy on on amazon. Really, you'd probably learn more by buying one, ripping it apart and reassembling it.
>But its voltage ripples like shit under load with the pcb i bought.
Add a small LC filter at the output of the converter, most of these Asian switching boards have shit capacitors with high ESR.
No, they want dumb men with fat paychecks who are easy to manipulate through pussy access denial.
Take it from a NEET who literally spends every day reading, learning and experimenting. Its a double disadvantage. Too smart to be manipulated by a dumb cunt, too poor to be attractive. That said if i won the lotto i wouldnt live my life any differently. I still get my dick sucked regularly just by acting stupid though. Fuck im lonely.
