Inside a Pound shop car-USB charger (with schematic)
I'll warn you in advance, that if you want more from a USB charger than a measly 500mA then this one isn't for you. It might have uses for powering low current devices though.
This came from a generic pound shop as opposed to one of the higher profile ones like Poundland. Now I want to get a recent Poundland car-USB charger and compare them.
The one good thing about this charger is that it shows how minimalist the circuitry can be in a mass produced device when they can justify using a dedicated buck converter chip.
If you enjoy these videos you can help support the channel with a dollar for coffee, cookies and random gadgets for disassembly at:-

This also keeps the channel independent of YouTube's advertising algorithms allowing it to be a bit more dangerous and naughty.
