Crikey. Y_A was right. SOME Home bargain have got discontinued stock of Powerbanks for 99p
They're only 1,500mAh but come with either iphone or micro(?) USB sockets.
Now.... 1,500mAh is barely a good set of 3 AAA cells, but they may be worth it just for bits.

A micro usb lead costs that
Can you crack one open or do some measuring.....
I'm guessing 3 or 4 aaa rechargeables in there and probably some charge control circuit? Maybe a boost converter to get them to make 5V? Can you see what charge current they can put out? upload the spec sheet?
Tempted. But at 1/10th the price of something 7 times better, they are borderline.
I just wonder if there's anything else can be done with them? Pair them with those poundland head lamps?
Often the whole 'making it work as USB' thing either uses dreadfully wasteful resistance circuits or coolio buck/boost converters. Since I discovered those converters, I fell in love with them.
Pity they don;t have usb c
Lithium polymer battery miss Jenny not aaa cells
