"Making our own power bank" sounds interesting but what is the use of making the thing which is easily and cheaply available in the market???

            First of all I would like to tell you that the cheap power banks of local brands available in the market , most of them uses the degraded batteries in the power bank and hence those power banks fails to charge the phone or gets exhausted by charging 4-5 phones. So I would prefer you to buy powerbank of trusted brands only.

             But those branded power banks costs a lot and here comes the importance of making our own power bank.


Advantages

> Cost is less.
> We can increase the capacity to whatever limit we want.
> We can make our own customised casing(Outer body).
> If battery's charging cycles exceed it's limit, than we can just replace the battery and we get the whole new power bank.


Things required

1.LiPo battery.( I have used a 5500mAh LiPo battery.) 
2.DC - DC boost convertor module.
3.LiPo battery charger module
4.Card board board ( for casing)




LiPo Battery


These are very slim, extremely light weight batteries based on the new Polymer Lithium Ion chemistry. This is the highest energy density currently in production.Do not attempt to charge these with anything but a specialized Lithium Polymer charger. All the smart phones, Tablets and even wearable uses this type of batteries.


DC - DC Boost Convertor Module

This module takes 0.9V-5V as input and boost up the voltage to 5V. Output current of this module is 600mA. In market, different types of modules are available but I will prefer you to buy one with attached USB port so that you don't need to solder them separately.

This is the link from where I have ordered this module:

TP4056 Lithium Polymer battery charger module


 The TP4056 IC is a complete constant current/constant-voltage linear charger for single cell lithium-ion/Lithium Polymer (LiIon/LiPo) batteries. Its SOP-8 package and low external component count make the TP4056 ideally suited for portable applications.Furthermore, the TP4056 can work within USB and wall adapter. Other features include current monitor,under voltage lockout, automatic recharge, and two status pin to indicate battery charging(RED LED), and full charged battery (BLUE LED).

Note:It is preferred to use this type of specialized charger rather than any 5V charger otherwise it may harm the battery.

             This is all you need for making your own power bank. If you still not cleared about this, just watch the video of Making your own POWER BANK" whose link is mentioned below.

             Hope you got the idea regarding power bank.

  2. A Power Bank is nothing but a compact, portable battery charger. These devices can be used for charging a broad range of battery-run digital products from laptops to small handsets. You cannot take your USB chargers everywhere. Even if you take them, you may not get the proper place to plug them in. A power bank does not need external power all the times to recharge the sets. Power Bank 10000 mAh are good enough to get the phones recharged till you reach back home or office. Modern power banks use a set of USB chargers through which they can recharge more than one device at one time.
