Powerbank
Powerbanks are mostly popular for charging smartphones and mobile tablet devices. A powerbank is a portable device that can supply USB power using stored energy in its built-in batteries. Powerbanks usually recharge with USB power supply. Basically, powerbanks comprises the rechargeable batteries, consisting of either Lithium-ion or Lithium-Polymer cells and comes under protective casing, guided by sophisticated PCB ensuring various protective and safety measures.
Specifications:
Capacity in mAh: mAh stands for milli Ampere-hour and measures the amount of power flow that can be supplied by a certain powerbank. Amount of mA × time at 5V ideally. Many manufacturers measure this at the voltage of battery inside, hence they show more than actual.Simultaneous charging and discharging: need to specify if the powerbank 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, better the powerbank. This can vary from output port to output port.Input Current Rating: Input current rating is the amount of current the powerbank 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 powerbanks.LED Indications: The Led glows as per indicating the amount of charging ability left with the powerbank
