Power bank

First of All. Most of people in modern world use smart phone as their personal phone. We like to play games on the phone, watch movie on the phone, playing internet, etc. All of the things that I mention before consume a lot of batteries. 

If you do all of the activity above on your smart phone, it might probably last only 3-4 hours.

And this problem can be solve by using power bank!!! 

Power bank. Just like its name, it can be use as a portable charging device. you have to charge it in order to keep the power inside the device. Then connect it with your device and finish! your smart phone are now charging. The problem of battery run off is now solved.

There are various type of power bank that you can choose according to your life style and budget.

It can be large, big, blue, red, light, heavy, high capacity, low capacity, good material, bad material, expensive, cheap, etc.



It is your choice that you want to buy it or not but for me i think this little device is very useful.
Imagine if you ran out off battery, you cannot contact anyone and there are some problem that you have to use your phone. It's bad right? So I feel more comfortable having power bank with me.
But yes, there are some alternative choices that you can choose instead of using power bank such as
using a normal phone(Sumsung Hero) because the battery life of it is really really long.


In the end, you have to decided on your own which way is the best way of you. But for me

I choose to use power bank.
