Why Buy A Power Bank
In this modern age where smartphones are not just luxury but the necessity for almost all individuals. People are looking to their smartphones for more than just sending text messages or calling. Techies and non-techies have all been hooked to one of the most popular cool gadgets of this era, and have found several different ways to enjoy their hand-held buddies. Unlike in the recent past when the inclusion of games to a mobile phone was enough to create a huge shebang; people now look for, insist on, and ultimately find, the things they need from their phones.
These powerbanks are extremely easy to use and very handy, allowing you to keep all your electronic devices active throughout the day. Since power banks can charge anything, they will allow you to keep connected to your Facebook and e-mail at all times. You need to have smartphones that have huge battery life so that you don’t have to worry about your smartphone battery dying in the middle of your conversation with loved ones. And if you are very heavily using your mobile phones then you can op for good power banks. Here are some of the best mobiles phones that have extra ordinary battery life. Power banks are definitely convenient and portable. After all, mobile phones are important for all different reasons like checking up on the kids, calling in to work, or ordering pizza and we wouldn’t want to run out of battery. But of course, they are also not without their disadvantages that equally and neutrally need to be taken into consideration.
Power Bank – An Overview
You can find many definition about power bank all over the net, but to simply put it is an electronic device that has an circuitry which is controlled and guided by small micro controller with plastic casing to store electrical energy and let you use this energy afterwards to charge other electronic devices like mobile phones and tablets on the go. Power banks store energy in an internal Lithium Ion battery and can charge the mobile and tablets. They are nothing but a special battery encased in special casing along with required circuitry to control the flow of power. That’s how I can explain them in a non technical manner. All power banks basically have the same function – to charge electronic devices on the go.
There are basically three 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. They store the energy in them just like you deposit money in the bank and have a means to charge a device like you withdraw money! That is the perfect analogy. Now that the battery capacity of the devices we are using these days has gone too low what we have been expecting it to with a myriad of tasks being performed, there is a need for an auxiliary power supply and that’s where these power banks come into action.
Power Bank Vs Mobile Battery
As we earlier said, even with high capacity battery your mobile phone won’t remain charged more than six hours if you are using it heavily in playing games or listening music. So you may need a power bank that can keep your phone charged even when you are out and away from an electrical outlet. Though they can be charged from sunlight, but usually people charged it via cable as charging though sun takes considerable long time. The last type of power banks are the one with battery phone case. These type of power banks are not so popular as they can be used for only specific type of smartphones.
Choosing The Best Power Banks in India
There are many models and brands of power banks available on the market. Not all power banks are capable of charging your smartphones fully. It is important that you understand about the features that you need to look while buying 10000mAh power banks of 2016 in India. The core of every power bank, as you can guess, is the battery cell (or battery cells) There are two main battery chemistry that are used for power banks and each chemistry has its own advantages and its own limitations. Here are few things that you need to look when buying power bank. Here are some features that need to kept in consideration while buying a power bank
This is the most important deciding point in choosing a right power bank. Power Bank capacity refers to how much charge is inside a power bank battery. It is measured in mAh or milliamps per hour. But one thing you need to understand that when a power bank is charging your smart phone or tablet, some of the energy is lost in transfer of power. So the real capacity is about 60-65 percent of the battery capacity listed on the power bank. For example a power bank with battery capacity at 2200 mAh has real capacity in the range 1320mAh to 1430mAh. 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. Below guide will help you.
What type of devices are you going to charge with your power bank? Take into account the power requirements of all the gadgets like smartphones, tablets, iPads etc that you will plug into the power bank. By doing so, you will make sure to opt for the appropriate amp level of your power bank. A power bank with a smaller output current of 1A level means that your smartphone will charge at a slower pace. Also, keep in mind that low output current might not be powerful enough to charge larger devices such as tablets, especially if the gadget is in use. If you are planning to charge larger items, make sure to decide on a higher output level.
We earlier talk about efficiency and that power bank with certain capacity can not charge a smartphone with the same capacity battery. Older phones have battery that use to last long, but today’s smartphone batteries drains out fast owing to more function the mobile phones have and hence the more power is consumed by the phone. Many smartphones will “lose” up to 10% within a few minutes of coming off the charger.
You should buy a power banks that is small and compact that makes easy to carry in your hand or pocket. Whilst smaller is better for portability, bigger could be more important when it comes to capacity. Power bank capacity is measured in “milli ampere hours” (mah) and different models range from 2,000mah to 20,000mah. For practical purposes, charging an iPhone 6 needs a capacity of about 1,600mah so if you want to charge it once, you’d buy a powerbank with 1,600mah capacity. If you want to charge it twice, you’d need a powerbank with a capacity of about 3,200mah or more.
The input rating of your mobile device is very important because this is critical in choosing the right power bank with a corresponding output rating that matches the input voltage and current. Choosing a power bank with an output rating higher than the input rating specified on your smartphone can damage the internal battery. The input ampere rating of a power bank is something that actually determines how long it would take to get charged and is most often found to be either 5V-2A DC or 5v-1A DC.
Disadvantages of Power Bank
Having a power bank is also having a means at preventing something you do not like, which here is letting your battery drain. Some people have the tendency to plug smartphones into power banks even when the batteries do not need re-charging yet and with prolonged excessive use, this could actually lead to making the smartphones battery life run shorter than it already did. ower banks are batteries themselves and will also need charging. Besides your smartphone, your tablet, laptop, you might even have portable Wi-Fi, do you really want to add a power bank to the list of things you need to plug in to a wall at the end of a day? Too many wires.
How Power Banks Work
Most power bank batteries can be charged by two methods either fast charge method or slow charge method. In a fast charge method your external battery can be charged under two hours. While in slow charge method it can take upto 10-12 hours. No one would like to wait so long to charge their batteries, but it has its own advantage. The slow charging does not need any charge detection circuit and also they are comparatively cheaper.
Most commonly, a Power Bank will have a dedicated input socket for receiving power. This power can come from a USB socket on your computer, but may charge faster when using a wall socket adapter. We most often see Power Banks use a Mini or Micro-USB socket for charging, and full-sized USB sockets for discharging. On very rare occasions, Power Banks can use the same socket for input and output, but this is rare and should not be assumed of any Power Bank, as trying to force power into an output can damage the battery. Always check the manual for specific instructions if you’re not able to find a clearly marked input socket.
