Guys if you travell alot and you are a really heavy smart phone user and you spend more time away from your charger.
Then you should have this product with you evrytime.
One day I was travelling to mumbai from rajkot my phone’s battery was about to die and there was no option to charge it and I had to call my friend to pick up me that was really unhappy situation for me then the passenger near me gives his power bank to charge my phone that time.
There are many brand’s and different types wirh many capacity you will find but the one I personally use and that works best for me is intex.
Its capacity is 16000 mAh.
It can charge two devices at one time.
I always take it with me when I travel.
And I recommend you too to take one with you also. It is really helpful.!
