in a previous video we looked at this Hamilton high power USB charging socket and we thought how
did they manage to cram 45 watts of charging power into double socket so in this video we're going to
take a closer look inside the glasses first can i give you the old Roy Orbison there thank you all
right just got to take the two sort of rivets off the front that hold the earth bar in place
okay come off maybe oh look at the first attempt in a minute
you know while you're trying to get that one off okay so just notice the speedE out
of the corner you're bringing that in as well i always like to get the speedE out
different coloured it didn't seem like the plastic with it
speedy regular viewers to the channel may notes were in a different part of
the building now for this teardown and Gary thinks the actual floor slopes i
just think he looks smaller because he's getting old and he's shrinking
okay the outlet for the water to run down is in this corner and i've got a funny feeling it
always slopes down to that area i don't see any taps six screws on this to hold it in
obviously i don't recommend doing this at home
we're using the speedE i don't recommend it at all
okay a little look a little bit more use a technical
one of your older screwdrivers NO it's one of yours yeah popped off right all right here we
go so this is the bit where it depends where the biggest of the nest in the front if i remember
on the last Hamilton wall everything sits on the back okay so if i lift the front off
bingo so just before we lose that we'll see that there's our switch mechanism and the springs for
the shutter okay we'll notice the uh it's got a whiff of being well engineered straight away
look at that yeah it's a neat injection molding uh so first thing this looks to be single pole
which sort of shows you one of the first how where they've they've done this
i had a lot of room been taken up as well and they have got a lot of stuff in there aren't they yeah
so there's our shutters we'll remove them from the socket yes look here's the switch so that uh
without the mechanism in it it's just there you can see so that they're actually single pole
where normally uh we're used to seeing software just double pole but something's obviously at the
give to get a little bit of compromise there isn't yeah and if we trace that back out so that we can
see the neutral backup of that terminal there how does it find its way across to the neutral
ah it sort of leaves the socket contact there yeah wanders down there around
up behind the line and into there that is yeah good engineering again yeah i've used every every
available millimeter so what i'm trying to do is ping those bits out so that's part of the live
part there so here's our USB power supply in the middle
so the interesting thing is obviously what you worry about in power supplies is isolation between
the primary and the secondary so here's the here's the line connection made there and the neutral you
see just soldered onto there drops into the primary the power supply has got a fuse there
we've got a little bit of surge protection we've got an EMC filter and the front end of
our power supply and these are high frequency transformers um so always worry about getting
the right isolation between primary and secondary we can see we've got double
insulated wire coming off there onto the lower voltage side which one does that to
our USB sockets and just see how much room we've had to create in the socket to do that
so again that's good so these look like thermal transfer pads when you normally see these so yeah
so they sit under some of the components to get opposite 45 watts we've got some um
power to dissipate and i've got a thermal transfer pad in there to do that
so this uh sticks onto the components on there so it's like a sort of putty substance
actually helps transfer the heat to the outside of the unit
so again we can see uh there's the the protection between the primary and the
secondary sides to give us the required level of voltage isolation between them
there's actually quite a bit of electronics in there yes that's quite a neat little unit
so i think this is a really well engineered solution by Hamilton and on the back here's
all the marks you'd expect to see with in relation to the British standards it complies
to but ultimately that comes down to trusting the manufacturer and we do trust Hamilton i've even
got one of these uh predecessors of this installed at home and it's still working which is always
good but some people we don't trust Gary no we don't and we did another tear down on something we
called the universally dangerous socket outlet if you want to check out that video it's over there
