2013 revolution- The coming of high end lithium polymer battery 10000mAh

Buyer- please understand what is li-ion,li-polymer,lithium battery type

What are the differences between power banks available in the market?

 User may be confused with various brands and type of portable power bank which are available in the market today if he or she is not familiar with battery specifications and functions. Power banks is different from one to another even though the battery capacity is exactly the same; in terms of size, pricing, compatibility, cell quality, cell grade, as well as the internal safety design.

What are the various battery/cell types in power banks?

-The battery type use in power bank might be in different too from one to another. Due to the high manufacture cost for high-end Lithium-Polymer battery cell comparing it to Lithium-Ion, therefore, the price of power bank equipped with Lithium-Polymer battery is always rather higher than the power bank equipped with Lithium-Ion battery.

f a smartphone cell is 1600mAh, does this means a 4800mAh power bank can charge it 3 times full charge?

-It depends actually, it does not translate directly into triple the usage time for the device with a ratio of 1:3. There is a calculation formula for the approx device charge per cycle for a single power bank charge.  4800mAh is only an indication on how long the device can power itself from the battery. All these factors will depend on the power bank cell quality, cell actual capacity, cell PCB board design and cell reliability.
