honestly i'm not 100 sure which one i'm
going to use
hi i'm matt and this is not enough tech
i have a small story to tell you might
notice the different parts of the video
is going to have a different lighting
and this is a reason for it because well
i've messed up and i had to reshoot it
during the daytime
okay to the main part we're going to
talk
about usb usb pd in particular but
before
that let me tell you story about this
this is
a lenovo yoga it's a very flexible
hybrid between a tablet and a laptop and
i bought it because it was slim
and nice and i needed something with a
decent battery life
and i want to take all the space in my
bag
next to this computer there was a asus
with a similar specification with a usb
type-c charging and 150 pounds
dear price tag which well as you can see
i've ended up
saving it's a decision i regret for a
very particular reason because every
time i go anywhere
even though the laptop is nice slim and
it fits
anywhere i want i need to take this
because
well it comes with a dc charger like
that
and pretty much all that space-saving
decisions
went out of the window so if you follow
this blog for some time you know that
i complain about gadgets without usb
type-c port
or i give extra marks in my reviews for
gadgets that
do come with usb type-c why because we
should have made a switch long time ago
usb type-c it is backwards compatible
which means you can
actually put a port and still operated
with a usb 2.0 specification
manufacturing reason for that is that
micro usb is
less expensive and it's easier to
integrate in existing
circuits because usb type-c needs
special secretly circuitry to operate
correctly
but it is worth it so today i'm going to
take advantage of usb
type-c pd pd stands for power delivery
and hack my laptop usb type cpd is
clever indesign
but i'm not going to get into a many
details how it works
for the purpose of this video you need
to know a couple of things not all
usb type-c ports are the same and not
all of them come with pd standard
it's important distinction because the
standard usb type-c port can transfer up
to 15 watts of energy
this is 5 volts for typical usb
specification
and up to 3 amps so that's easy
the pd specification split into 4
different voltages we have
5 9 15 and 20 volts available
now all together it can transfer up to
100
watts however it gets slightly more
complicated than that
all you need to know for now is that 5 9
and
15 volts are limited to 3 amps of
current
and to achieve 100 watts of power just
to the mass
20 times how many amps it's five
despite my pro purchasing decisions i
was slightly in luck because this
charger
actually comes with a speed following
specification it will deliver
20 volts at 2.25
amps for the total power of 45
watts that's great because i can totally
use one of these connectors to
transfer significant amount of power to
charge the device and keep it
operational
but i still have to solve two tasks to
make this conversion
possible first of all i have to say if i
have enough space inside of this laptop
to accommodate for the extra electronics
that's gonna go inside second problem
i have to explain to the charger that i
need to draw 20 volts
out of this to power my laptop that's
not going to be figured out on its own
and i'm going to use this clever module
that has been programmed to do so
so as soon as the compatible charger is
connected it will tell the charger that
this particular socket need to draw
20 volts before i made any permanent
damage
i just wanted to make sure that i do get
20 volts
on my charger with this module and this
indeed there's a 20 volts spawn
so i started with a obviously opening
laptop there is advantage of buying a
cheapest
sku from a particular model because you
ended up with a plenty of space
inside the laptop where would be all the
premium components
and indeed that was the case and the
majority of the space inside is just
not populated and i could easily find
space for my module now i was even more
lucky with the
dc connector which was separated from
the motherboard
and there was a cable i could pull out
which was attached to the motherboard
with a
connector so um the idea of swapping the
and this connector was very very simple
i had to do is just
unscrew the bracket remove the dc
connector
solder soldering the new one and i was
ready to go
because my connector is slightly bigger
than the old one i knew i'll have to
dremel out
some bits to make space for it now
before i gonna make any permanent damage
to my computer
i investigated it again the polarity of
the connector to make sure
there is no mistakes and then proceed
with
butchering of the cable
i didn't even make a template for usb i
just kind of
kept it near on the circuit and proceed
trembling out the metal and the plastic
bits inside
i was very careful because on one side i
had a light and i really wanted to
retain that
charging indicator now in hand side i
should have used a plastic bag to secure
motherboard the pcbs from metal
chippings because they could cause a
short
so it took some extra time to actually
clean up the mess i've created with a
dremel
and i'll use some painters brush
to kind of pressure off all the
chippings so if you're watching this
before you actually start doing anything
i would strongly recommend you to use
that
all right this is a final job and it
doesn't look bad actually there's a
couple of scoffs because my
dremel slipped but yeah it looks alright
now it was time to change the cable it
was just the two cables so it's a very
simple soldering
job again once and the soldering was
complete i've tested the cable to make
sure
it's all right then i use piece of
electric tape to isolate it
and i had to use couple of extra stripes
of the tape
to create a bit of a tension between the
retaining mechanism
and the usb type-c module once i screwed
in all the screws
and the socket was in place secured then
two with
lenovo yoga usb charging
i'm super happy because that's going to
be the only charger i have to take with
me when i'm going on holidays but i'm
going
somewhere else well it's a lot down for
now so
if you're watching it at the present i'm
not going anywhere if you're watching
this uh
video in the future then known that i
wasn't able to actually go anywhere and
benefit from that for a couple of weeks
there is one more thing i've learned
while making this
video i've discovered how different are
the charges offered out there
and i spent a lot of time actually
looking for compatible charger
for my travel i wanted to quick charge
all my phone's
laptop and have the ability to power
another usb type-c
device and i only found a handful of
devices capable of doing so
one of them is going to be discharger
which i'm going to review very very soon
so do pay attention to the specification
not just power
rating estimates because they always
often combine
all available charging outputs all right
guys i hope you enjoyed this video
learn thing or two do you have any
gadgets that are you willing to convert
this way
let me know in a comments section to
this video
additionally you will find a couple of
links and a detailed tutorial
about this project linked in the
description of this video
thanks so much for watching and you
probably know i do not have a posting
schedule so if you want to be in such
it's best to follow me
on the social media of your choice which
is listed just
and you'll get a notification whenever i
have an article
or a video coming so whatever you do
be creative and i'll see you in the next
video take care
bye
