It ships with their power bank, independently it seems to be unobtanium at this point. Lenovo has a similar USB C to older 'slim tip' cable, the 03X7530, which they claim - but so far this is unverified - to be a standard part. They also sell a Magicable with it which makes the charger usable with many older non USB-C laptops but alas it seems it's only for the Innergie charger only, it's not a standard part. When Innergie was running their Kickstarter, then named 55CC, they were getting some coverage in 2017. The TL431 is extremely common in chargers to provide the feedback for voltage regulation, but apparently it's being used here to drive the LED. There's a TL431 voltage reference chip next to it.

So the big controller chip replaces multiple components in a typical charger. The control chip also contains the MOSFET that chops up the input voltage. But this control chip connects to both the input side and output side it contains an inductive isolator internally. Most switching power supplies have an optoisolator to provide feedback between the output and the control chip. This improves efficiency because you don't have the voltage drop you get across a diode. This is called synchronous rectification. One somewhat advanced feature is that the output is not rectified by a diode, but by a MOSFET controlled by the controller chip. The output from the transformer is rectified, yielding the low-voltage, high-current DC output. To oversimplify, the incoming AC is rectified to DC, chopped up into pulses that are fed through the flyback transformer.

The switching power supply is a quasi-resonant flyback topology.

I believe that works out to about 8 Cray 1 supercomputers using the Dhrystone benchmark. This chip contains a 32-bit Arm Cortex-M0 CPU running at 48 MHz. The charger has a separate daughter board for the Cypress USB-C controller chip. One interesting thing is the amount of complexity that USB-C adds. The one sketchy thing is the charger panel that just pops off (instead of being glued/welded), potentially exposing the user to high voltage. It looks like they built the charger with reasonable quality, not cutting corners, but it's not at the Apple level of (over-)engineering. Ha ha, thanks! I agree with you that it looks okay from a safety perspective. I was looking forward for Ken Shirriff-style charger reviews
