tonight's teardown is easily assisted by Fort Gary brewing's dark English mild ale
they describe it as a chestnut colored English mile there with caramel coffee
and chocolate flavors and a balanced hot finish and yeah this is one of the first craft beers
in this area and I've been drinking it for years and it is really really nice
so to Nate I am going to be messing with this little charger here that I got in a mailbag not
that long ago it calls itself Quick Charge 3.0 but I don't think it is a quick charge a QC Quick
Charge charger and the business end here it's got four brightly colored plugs and they all claim to
be 3.1 amp I am skeptical what are the claims does it make it's input voltage between 110 and 240
volts for the 60 hertz that's very typical half an amp okay uh output 5 volts DC 3.5 amps Max times
four I am skeptical that there's three and a half amps times four comes out of this or even 3.1 amps
times 4 comes out of this I would be surprised if it could even do three amps total spread across
four of them and of all the bogus creams that's probably going to be the easiest one to test where
is all my things uh so yeah let's just play with it and see what happens putting into one of those
doesn't matter which one for this plug in my load turn it on and see what it says okay so right
now it is just idling it's got half an amp it is providing five volts 5.05 that's cool let's start
cranking up the load and you'll see that going up place your bits as to where this thing falls apart
as they've already said it's probably not going to make it to 3 amps because that's my bit anyway
um I'm thinking probably closer to two because that's much more common in this
type of power supplies there's one and a half amps and it's still holding cool
1.6 1.7 still holding I'm pressed
oh oh starting to drop off where does it just leave five volts it's crank it back up to here
right there just above 1.8 amps okay and craters wow so not even two amps that's even worse than
I thought okay we'll Crank That Back Down and we'll try something else let's see if it can
I'm gonna guess that that two amps is spread across all of them so I am going to bring in
another USB mode this is just a fixed one amp or two amp load we'll throw that into there I'll
plug this guy in at the other end if I get the USB the right way up this thing is drawing currently
150 milliamps so let's crank it up and watch and see what happens half an amps that's one
and a half total 1.6 total and the voltage isn't cratered yet 1.7 oh we're starting to lose it
yeah there we go so that's basically the same that's more or less two amps across
a couple of different outputs and the voltage is already starting to drop off so there's no
way this thing is capable of three amps across all four even three amps across any one of them
so already it's horribly annoying to me shall we see if it's got any circuitry inside that's
interesting at all or is it going to be just a cheap auto module that's my bet
so how do we get into this thing there it doesn't look like there's any screw holes or anything so
we are up for a spudging good time can I get into there without hurting myself uh
doesn't look like there's any gaps or anything right
just give it a little bit of stress along the glue line with the Plumber's friends here
there that feels nice and crunchy now can I get in there
still no hmm
oh wait there we go
hmm
okay I'm going to have to throw all my sponges at it again here's those other ones
something like this maybe
foreign oh there we go just need a little bit of
abuse oh wow it's an AC input just kind of prongs into here all right
um yeah so all I'm seeing on here is a very standard switch mode power supply
we have one side of the AC line going to a bridge rectifier we have the other side of the AC line
going through this sort of low value resistor probably a fusible resistor to the other side
of the Bridge rectifier the DC output from that one side it looks like it goes into this chip
um this capacitor is across there smoothing it out a little bit yeah we have a gap between the high
voltage the AC side and the low voltage side that makes a certain amount of sense and that
goes right underneath this Transformer we have the diode over there coming right off the Transformer
jumping into these pads over here wow that is a smoothing on the outside is there anything
okay so there's just this little class is that even so this little capacitor down
here according to the silk screen claims to be class y but there's no markings at all on that
little capacitor it's supposed to provide a little drain back but yeah there's nothing there I don't
see any feedback components on this thing jump in the gap tell this guy so it's not even very
well regulated on the output side there's only one two little resistors that diode that capacitor and
that led in there so uh how would I assess this it's crap basically um it's I mean they've made
a slight effort at putting a gap in there but the weak spot's probably going to be in the wind is of
that Transformer and I don't have the patience to tear it apart uh I mean it does the job
um it's not going to be the smoothest of output and I'm if I was to put the scope on it as the
current was getting up I would bet that it would start getting out of Regulation pretty quickly so
yeah um It looks interesting and colorful but definitely rated do not buy it certainly doesn't
live up to its promises it doesn't have the brains inside it to do the Quick Charge modes
I didn't even bother testing that because it's just no point I suppose I could try and look
up the part number on that thing but I don't hold out much hope that I'm gonna find anything
if you want to try it yourself it's a c5783 and there's some other numbers down there
I think that's 2725 a oh I'll take a look and see if I can find anything but like I said I'm not
holding out much hope yeah that one didn't come up with anything this is not at all that it's just
a transistor other set of numbers came up with again just nothing in particular that's relevant
yeah well it was worth a shot I suppose so yeah absolutely nothing surprising in this
one except for just how much it was lying to us so if you see something like this for sale
don't get suckered in by the promises of you know four times three point one amps or quick charging
or the fancy colored uh USB Jacks it is just a basic cheap less than two amp USB power supply
not much else to say about it um I'm not disappointed I'm not surprised that's exactly
what I expected it to be but you know you've always got that one percent hope that it might
be something good but there you go I wasted my money so you don't have to waste yours
that's kind of what I do around here on a lot of these things anyway uh thanks for watching
that was uh that was a quick one I will be back next week and talk to you later
