I am now talking about Lenovo PA13000 mAh power bank. The power bank is very good and nice product. This is very useful when u use the it for journey. The product have the capacity 13000mAh that is you can charge your phone fully upto four times. This product is very light weight and good looking compare to the other peoduct.
Do not belive on the bad reviews, it is good and I highly recommend to you. Its battery do not get drained and you can recharge 3 mobile at a time.
