Inside an EDC V3 flashlight (with schematic)

I'll just assume that this unit is a clone of one of the many similar looking products. It's hard to tell which came first in a sea of lookalike products. I'm sure the true flashlight connoisseurs will know.
In the UK we call these torches, which is kinda bizarre, since it's literally a progression from the original blazing stick that was used for light in the long distant past. According to Wikipedia the word torch comes from the French word torche, representing the fuel carrying wick wrapped around the end of the stick. So basically speaking this torch is an electronic blazing stick that fits on your keyring.
This link finds them on AliExpress. Target price around 10 pounds.

The lithium cell claims to be 500mAh, which is viable for its size, and it is charged at a current of around 350mA. The USB C charging port does not have the load identification resistors, so some smart chargers may not detect its presence and will not charge it. A plain dumb charger will charge it.
The front LEDs have five modes. Brief high power output and four latched intensities, with current draw at 4.2V as follows:-
Momentary high power = 2000mA
High = 660mA
Medium = 140mA
Low = 67mA
Night light = 13mA
The small side LEDs have two chips each and are run at 100mA.
If you enjoy these videos you can help support the channel with a dollar for coffee, cookies and random gadgets for disassembly at:- www.bigclive.co...
This also keeps the channel independent of KZbin's algorithm quirks, allowing it to be a bit more dangerous and naughty.
