ARMdevices.net takes a look at the Veger Power Bank Factory. Looks like a nice factory that can produce 10,000 battery banks per day.They have a nice assembly line but at each step I seemed to be thinking slow down. Speed is the name of the game here. I can see where those dodgy China solder joints come from by watching this video. Is the step at 5:07 the extent of the operational test? I would have expected something a bit longer. But I guess when you are building a product with a price of $3.90 you need to be fast.
