    I'd give it 0 starts if i could. Maybe i got a defective one but it never charged. The lights came on but it never did an initial charge to even let me test if it worked with my phone.

    Portable battery charger is convenient yet it can drain quickly. Initial setup, this device takes some time till it's fully charged. There is no pouch with this model. Thinking to go ahead and take it back for a refund, or just exchange it for a new one.

    No, I would not recommend this to a friend

      Kindly note that in order to get a sustainable supply of some components/materials, we have canceled the pouch for some of our products. We have updated the listing to remind the customer that the pouch is not included in the "What you get". So sorry that this does not draw your attention and causes an unpleasant experience. anker
