Power bank battery technology tips:
Dual Output & Input: Each has 2 USB output ports that detect all the connected devices and efficiently distributes the current output up to 5V 2.1A. The USB C and Micro USB ports can fully refill the battery itself in 10 hrs at 5V 2.0A.
Reliable Li-polymer Cell: Thanks to the Li-polymer battery pack, the charger is much safer than any Li-ion charger. Also, it's lighter and slimer that you can easily carry it around, even on airplanes.
All power banks use rechargeable batteries based on lithium technology. Lithium-Ion and Lithium-Polymer batteries are most commonly used for power banks. Battery technology is the key to many new developments: everything from mobile phones to electric vehicles, and as a result it is quite likely that there will be some spin-offs into power banks.
These two currently used technologies have slightly different properties:
Lithium-ion: Lithium-Ion batteries have a higher energy density, i.e. they can store more electrical charge in a given size or volume, and are cheaper to manufacture, but they remain aging problems;
Lithium-polymer: Lithium-polymer power banks do not suffer from aging problems to the same extent, which is a better choice. And it provides you high-speed charging to enjoy. The disadvantage is that they are more costly to manufacture and as a result they may not fit the budgets.
