hey what's going on guys its kedar here and today you can get this power banks for
really cheap price
I got this power bank for two dollars and you know it doesn't provide the
features that you mostly going to use like the pass-through charging so let me
show you that when i'm going to charge this power bank and simultaneously charge
my mobile phone it will not charge my cell phone
you can see so I'm going to charge this power bank and simultaneously going to
charge my cell phone
you can see nothing is going to happen there
but now you have removed the charging going to this power bank
it will charge my cell phone as you can see so how can we add the feature of
passthrough charging into these two power cheap power banks
so it's quite easy to just get this to lithium cells and connect them in parellel
now you can get this from your old laptop battery quite easily or you can
just solder together
just make sure that you don't put the soldering iron to this tabs for a very long time
the next thing you want to do is connected cells into one of the pow er
bank on to other side place other power bank
so after doing that you'll get this your power bank in which you have double the
capacity also you have two USB output port and two USB charging ports so now
you can charge through the one of the power bank charging port and is discharge through other port
and you can get by this way
a pass-through charging so let me show you that i'm going to charge this power
bank now and you can also stick this power banks together by any kind of glue or hot glue
super glue I'm going to charge
through other power bank
and it's charging
now you have two USB ports so you can charge two devices simultaneously and you
can get the same current output since so you have two lithium cells and you have
each individual driver circuit for the USB so you can get the high current output as
well as you can charge two devices simultaneously the most interesting part
of this power bank is that you can super-charge this power bank if you have
two USB charger or USB ports as you can see now we can supercharge this power
bank now for the charging circuit we have also two
driver circuits for each in individual power bank
so you can charge this power bank literally more faster than one port
we are charging through one port by 800 ma
so since we are using this duel ports we are charging our power bank with 1.6 amps
so in conclusion we have better power bank than
any kind of power bank that you can get in market
we have your USB charging port as well as dual USB output port so you can
charge your power bank at 1.6 amps so it needs half of the time to
charge it as well as you have dual USB output so you can charge two devices at
a time with same output current events so hope you liked this quick little
video of this power bank modifications and
stay subscribe for most of like this and please give it a big thumbs up if you
really liked this video guys and I'll see in the next one piece
goodbye !
