Lenovo PA 10400 10400 mAh Power BankBlack, Lithium-ion

Am writing after using of almost 2weeks. Takes minimum 4 to 5 for full charging. My phone battery capacity is 4000 mah. I can charge my phone for only 1 and half times. So battery backup is around 6000 mah. Was expected much better than this from Lenovo.

Received the product within two days of order.. The packaging was good.. Coming to the product, the backup time which is mentioned on the site is not the same as what you get in real life. Complete charging of this product itself takes approx 10 hours and after that you will be able to charge your device only 2 1/2 times... I have moto g4 plus with 3000 Ah battery
