One reason for me to leave the Power Bank unopened is it may open a can
of worms. Especially if it uses an undocumented, expoxied, exposed-lead
chip to control its charge cycle /and/ perform an automatic shutdown.
Also, my tear-down of the MP3 player to remove its battery and USB-B
port already sated my appetite to take things apart (for now). :)
You didn't comment on my MP3 player. Muchas Gracias. After all, the
player's merely an available adjunct to test my keepalive with a field
trial.
Although the keepalive functioned as originally intended, the prospect
to double its efficiency tempted me to replace R2's original 150 K ohm
value with a 300 K ohm. So my page now reflects R2's new value:
<https://crcomp.net/mp3mod/index.php>
The keepalive successfully functions on two distinct Power Banks
with different capacities, marketed under separate brands. Besides auto-
shutdown, both Power Banks also share similar design language [1], as if
they both originate from the same factory in China.

She set out one day In a relative way And returned on the previous night.

Hello Don, you're obviously a handy guy, so
why not just open up the power bank, and
bypass that 'auto-shut-off' circuitry?
Maybe you use this power back for other uses?
So you still want the auto-shut off?
I don't see the logic why that feature is needed
in the power bank, anyway. Any electronic device (beyond
a simple thing like a light) is likely to have its own auto-shut
-off function.
But you do want to preserve it, then I'd install a simple
SPST switch to select bypassed- or native-behavior
as you like.
cheers, Rich S.

He used a mu symbol, just your newsreader apparently can't
handle the way he did that.

Bull, I have many mp3 capable things, credit card size mp3 / video player, what not, phone
But my mp3 player is a 20 year old or so Creative Muvo, runs on an AAA Eneloop battery all day if needed,
easy to charge or swap, I concatenated all my favorite music into one long mp3 so it
can run unattended for many hours, and is small and simple to use.

I prefer no RF shit next to my head, you see what it can do to people ;-)

Silly

Check out this dusty fool foaming over some trash mp3 player that requires
an external battery pack plus some 555 hack nonsense to even stay powered
on.
Rediculous.

Run that through Google Translate again, this time choose English as the
target language.
