I covered this power bank on a recent video, but while messing around with it I disconnected the lithium cells then reconnected them. The unit went into standby mode and would not put out power or respond to a button press until it detected it was being charged, whereupon it sequentially tested all the LEDs including the flashlight one and then operated normally.
I have a battery much like that from a company called power add and I was doing some testing with it and it seems that if it gets short circuited it shuts down but soon has you put power to the bank it resets and works just fine
This must be the chip designers having fun, I wired a gate control recently which when first powered up played a tune using the clicking relays on first start.

What do you think about the "exploding E-cig" ? We can hear a lot about this now.
Like this article: “Exploding” e-cigarettes have caused more than 100 fires including one that was deadly, prompting a warning that more people could die unless safety warnings are displayed.
The Local Government Association (LGA), which represents fire brigades in England and Wales, said e-cigarette blazes have been increasing in the last two years and is calling for “graphic” warnings to be put on chargers.
I wonder if it was overloaded/shorted when you disconnected the power. I've had the battery protect IC do this and it wouldn't restart until charge was applied. Not exactly the same thing though.
P.S Loving your videos. Watching them "all" at 1.5x speed to the great annoyance of my workmates. 🙂
i noticed a similar thing when i bought one of those boards from ebay to make my own power bank,, i thought it was a dud, but i just had to charge it a bit and it started working, i think it is because it detects that the batteries (or lack of) have been over discharged and it just goes into battery protection mode.
if you use the batteries with the protection circuit it cuts off power in the same way removing batteries would.
LOL! I wold love to have one with the visible LEDs.
I guess this is for when the power bank is still in delivery/storage/laying on the store shelf/… so it won't drain the batteries until it's "activated".
