A look inside the Duracell PB2 power bank.
I got this from a large UK supermarket chain called Sainsburys but hadn't got round to doing a test on it yet. Quite well constructed with LG cells, an unusual control PCB with a few tricky to trace components and a thermistor for battery temperature monitoring. Notable features are the decent control chip they seem to have used and the matching beefy inductor.
External cell capacity test is a respectable 6400mAh. (3200mAh per cell)
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.
