Power Banks are almost regular things for everyone. But not everybody knows thoroughly about its functioning and uses. So, what is a power bank? It is a device that charges any other compatible with it. It has multiple USB ports used for charging your devices. They can even be wireless or induction-based, which uses wireless transmission for charging. Devices like phones, MP3 players, and wireless mouses are conventional when it comes to charging by power banks. Well, there are considerable advantages to the power bank and some significant disadvantages as well.
What Is A Power Bank: Its Advantages And Hazards
Most airliners banned power banks from their planes because of safety hazards. According to experts, low-grade power banks cannot survive high air-pressure and can explode, causing a potential hazard. The more the capacity of the power bank, the more damage it can cause. However, there is no risk if not exposed to extreme temperatures or high air-pressures.
These power banks are capable of storing charge and can share it with connected devices at any time. It can charge itself from 220V AC power supplies and then convert it through its circuitry while charging other devices.
Some power banks are solar-powered, meaning that they use solar power to charge themselves and then can charge other devices. Their circuitry includes solar panels and electrostatic converters that help in storing the energy into the batteries. However, these solar-powered power banks charge themselves very slowly, and it takes more than 3 hours to get 1500mAH of power inside the cells. However, the process is indeed green and energy-efficient. Therefore, environment conservationists are encouraging people to opt for solar power banks instead of regular ones.
Standard power banks are available at almost all online and offline stores. However, solar power banks are available in very few places. The costs of solar banks are expensive, but manufacturing companies are doing their best to equate the prices between standard power banks and solar-based power banks. The lifetime of charge inside a power bank when left idle varies on different brands.
Power banks self discharge themselves after a certain period. A fully charged power bank can take almost 3 months or more to discharge itself, depending on the brand and capacity of the cells. A good quality power bank can even take 6 months as it self discharge time.
Lithium Batters Most Common Type
Lithium-ion and Lithium-polymer batteries are the most common types of commercial power banks available in the market. Of these two types, Lithium-ion batteries are cheaper, but polymer ones are more durable. Polymer-based power banks are costlier to manufacture but can withstand uneven temperatures or environment. Between both these kinds of power, banks, power, price, efficiency, and performance are the only factors that come into play. You can choose any of them depending on these factors. Still, it is obviously advisable to spend on these products as they can get damaged pretty easily.
These devices give you a lot of advantage in places where there is no power supply or circuitry available. Often these become your alternative in case you forget your phone chargers.
