The best part I find about ChargerLab teardowns is identifying all the passive and discrete components.
Western distributors tend to only stock western/japanese brands of these, but they can make up a sizable fraction of the BOM (especially electrolytic capacitors) so knowing who the big players are comfortable with using is very handy. LCSC stock a lot, but its nice to know which suppliers have been proven in use.
