Your China-bought power bank could be filled with sand
There aren't even enough sand to build a sand castle!
A citizen of Taiwan recently bought a powerbank (made by companies in Shenzhen, China) with a very large capacity, it’s 24,000 mAh at a very cheap price. When it’s used to charge a cell phone, it’s fail.unitedgadget.com
Needless to say, the device above is actually a fake with the enclosure being packed with sands. That little cylinder next to the PCB board is the actual battery. From the looks of it, it'll probably be less than 2400mAh.blogspot.com
OR it could be filled with mismatched batteries
This picture is said to be taken from a newly purchased cheap power bank, opened up for inspection. Note that the colour of the 6 Li-Ion batteries are all different, which is very unlikely if they are manufactured from the same batch.blogspot.com
Also note that the soldering point is rusted and shows sign of multiple re-soldering. There is also leftover glue on the surface.blogspot.com
Genuine power bank uses either lithium-polymer battery cell or lithium ion battery
The battery type used in PowerBank might be in different from one to another. It could be a high-end Lithium-Polymer battery cell or Lithium-Ion battery.blogspot.com
