How do you know? Did you went there?

Even the charger internal components are beautiful than my whole laptop

It's very nice to see active input (A/C side) recifier circuits on more chargers. That should make this a very efficient charger that stays cool when in use!

A quality charger from someone who know what they are doing, Japanese Electrolytes 😻😻, this design actually makes as it uses GaN FETs as the main switchers. Low output capacitance isn’t a major issue due to the very high switching frequency which this should operate at and this should have enough input capacitance at higher voltage because of the APFC circuit so there is more energy.

I must say, I'm impressed! First charger teardown i watched. Didn't know this was a thing. Subscribed.

What I've never understood with Apple's chargers is the way they can't seem to decide if they are making a class 1 (earthed) or class 2 (double insulated) product. They have that earthing "button", but it only gets connected if you use the apple-supplied mains lead, if you use the plug heads it just gets left floating.

@DevynCairns

2 жыл бұрын

It's necessary to make a charger that works with a floating ground anyway, because some major markets (mostly Japan) basically don't provide earth on their sockets anywhere. Passing the ground through to the device through the cable is an added benefit where you're able to use it, but it's not a guarantee. And I'm guessing it would be harder to provide that folding design with the extra earth prong anyway.

Thanks for the nice video. Can you kindly tell me about LLC driver IC used. Best Regards & Thanks,

General question - how reliable is the USB-C connector when passing 5 amps? I guess it's only 1.25 Amps per pin (there are 4 ground and 4 Vbus pins in the USB-C connection) but it still feels like a lot for such a small contact area.

@peter.s.3207

2 жыл бұрын

The USB-C PD spec states 40 mOhm max contact resistance per power bus (i.e. VBUS is max 40 mOhm, GND is max 40 mOhm, etc). We can see at 2:40 that the Power-Z PD monitor is reading 27.75V, so assuming a perfect 28V regulated output this is 0.25V drop at 5A, or 50mOhm total, 25mOhm per power bus, dropping 1.25W at each connector. This is of course a rough estimate as we don't know the unloaded voltage or how close to spec the Power-Z PD monitor module is, but it seems well within spec.

@GodmanchesterGoblin

2 жыл бұрын

@@peter.s.3207 Interesting. I looked this up - I read 40mOhm per contact in an Amphenol spec. Since there are four contacts in parallel then it's nominally only 10mOhm in each rail so 20mOhm in total. 5 Amps through 20mOhm will only dissipate 0.5W in the connector which isn't great in terms of contact heating, but I am sure the designers knew what they were doing. I won't be so worried about this issue in the future. Thanks.

@peter.s.3207

2 жыл бұрын

@@GodmanchesterGoblin Oh that's kind of odd... I doubled checked the 40mOhm figure and it seems like different sources are saying different things (per bus vs per contact). I rounded up a short USB C-to-C cable with a power meter on both ends and got 25mV drop at 660mA, which is pretty close to 20mOhm per connector (plus the wire) so looks like that's indeed the correct value.

Will you be able to take a look at the Volta 200W GaN chargers when they are released to the public?

All the parts used seem to be really high quality to an amatour. What's your opinion, were there any cost saving measures used where using even more expensive component would have increased total efficiency of this charger or improve it expected life-time? Or is this truly no-compromises build for this kind of charger? (I think they could have made the charger not-glued case but that's obviously an intentional Apple design decision to avoid screws, not about making it cheaper to manufacture.)

Ummm, no the reason why the charger is slow is down to the chemistry of the cells it is trying to charge. As the cells become more charged they become more inefficient and will take more power but charge less as a proportion. You can charge them hard, but they'll get hot and you'll waste a ton of power and dramatically shorten the life of the cells. GaN will just make the charger smaller, it might accelerate charging a bit, but it won't allow you to fully charge a lithium chemistry cell to 100% quickly.
