Power Banks are popular for charging smartphones and mobile tablet devices. A powerbank is a portable device that can supply power from its built-in batteries through a USB port. They usually recharge with USB power supply. Technically, a powerbank consists of rechargeable Lithium-ion or Lithium-Polymer batteries installed in a protective casing, guided by a printed circuit board (PCB) which provides various protective and safety measures. Due to its general purpose, powerbanks are also gaining popularity as a branding and promotional tool. Different brands and promotional companies use it as a promotional tool and provide a customized product.


Specifications:


Capacity in Wh: Total power capacity measured by multiplying mAh by voltage.

Capacity in mAh: mAh stands for milli Ampere-hour and measures the amount of power flow that can be supplied by a certain Power bank at a specific voltage.

 Many manufacturers rate their products at 3.7 V, the voltage of cell(s) inside. Since USB outputs at 5 V, calculations at this voltage will yield a lower mAh number. For example, a battery pack advertised with a 3000 mAh capacity (at 3.7 V) will produce 2220 mAh at 5 V. Power losses due to efficiency of the charging circuitry also occur.

Simultaneous charging and discharging: need to specify if the Power bank can be used while it is charging.

 Number of output USB ports: This specifies the number of devices that can be charged simultaneously.

Output current rating: This specifies the current rating that it can charge maximum. The higher the number, the better the Power bank. This can vary from output port to output port.

Input Current Rating: Input current rating is the amount of current the Power bank is able to draw at its maximum level while getting charged.

Safety Protections: Over Voltage Protection, Over Charge Protections, Over Current Protections, Over Heat Protections, Short-Circuit Protections and Over Discharge Protections are the common safety measures observed with standard Power banks.

LED Indications: The Led glows as per indicating the amount of charging ability left with the Power bank
