Power banks are hugely popular today, owing to the increase use of smartphones not only for making calls and sending short messages, but also for variety of different purposes like watching movies, listening songs, chatting, internet marketing and using it as a means to connect with people using social media.
What are Power Banks
Power banks are portable device that are used to store electrical energy, these energy can be later used to charge your smartphones and tablets. They contain special kind of battery made up of Lithium-Ion or Lithium-Polymer with an electrical circuit to control power flow. Power banks are light in weight and small in size that can be easily carried in handbag or pocket. There are many brands of power banks available in India with different price range. Most power banks in India have the same function – to charge smartphones and other electronic devices on the go. There are 3 types of power banks on the market today. The most used power banks are ones that have USB ports and they are known as universal power bank. The other power bank is called as solar power bank. They use energy from sun to get itself charged.
Features to look when buying power bank
Choose power banks according to your need. If you want to charge up only your mobile once, then buy power banks that have capacity of under 5000mAh. But if you want to charge up multiple device including smartphones, iPad and tablets then you need to purchase power banks with high capacity in the range of more than 10000 mAh. If you’re searching for an entry-level Power Bank that are not expensive then buy power bank that have only one USB port and capacity less than 3000 mAh. For iPhone user, there are plenty of power banks that can charge up your iPhone multiple times. Here are list of top power banks for iPhone in India. If you are going for camping then the best choice would be a solar charged power bank that has capacity of at least 1500 mAh. It only has enough juice for about a half a phone of power, but can charge itself in about 6 to 8 hours of sunlight.
Capacity is one of the most important feature that should to be kept in consideration when buying a power bank. You must be hearing and seeing the various numbers like 5200 mAh, 10400 mAh and so on. The average calculation is assumed on linear regression (to make it easier to explain and demonstrate), however the actual charging profile is a non-linear regression meaning the current decreases more over time. These numbers are the primary things of course signifying the charge holding capability of the power banks. Depending upon your need, you should purchase the power bank that would have sufficient capacity to charge your mobile multiple times. If you are not sure, as how to determine or calculate the capacity then don’t worry.
So, if you are using a 5000 mAh power bank and use it regularly, 500 charge cycles will bring down its capacity to about 4000 mAh. This is very normal, as you are regularly using it and the reduction in capacity is bound to happen.But practically it will be less than 3 times, as you cannot use 100% of the capacity, some power is loss in transmission and in circuit resistance.
Phone Battery Health: The battery in your phone is strongest when it is new. With age and with charge cycles, the health of the battery keeps getting lesser. There are apps that test your battery health, and although they cannot be called 100% accurate, still would give an approximate estimate about the current health of the phone battery.
Power bank plug:Usually we saw there 2 port in power bank ,1A and 2A. This number show how much power that will use for recharge troughs that port. A means ampere. the power that will use for charging will determine how long it take full full recharge. As an illustration, Samsung Galaxy III have 2.100 mAh battery then it recharge from 1A output port, it will took around 2 hours for fill the battery.
Fake power bank:Price cannot use as standard. Some power bank give expensive price and say those device have more power than other. But after you using it, you feel that it could backup your device that it should be. Fake power bank could not give the power that they say.
Working Principle of Power Banks
Power banks that are portable compromised of electrical battery in case with a special circuit that can control flow of power. These circuits allows to store energy in a capacitor which can discharge power later whenever required. Power Banks have become increasingly popular as the battery life of our beloved smartphones, tabs and portable media players is outstripped by the amount of time we spend using them each day. A power bank is essentially an external battery in a sealed case. Power banks come with a USB cable; you connect it to a power source such as a laptop to charge the power bank. Some charge via flip out blades for plugging into the wall. In either case, you carry the charged up power bank – and the cable – in your pocket, purse, backpack, briefcase or whatever and use it to charge the phone (using the same USB cable) when you see the battery meter sinking into the sunset. Many portable power banks are actually integrated into the device case. Most will double or even triple your battery life. Many are even solar powered, meaning, that’s right, as long as the sun’s still in the sky you’ll basically always have power.
