Came with charge and charged three phones straight out of the box. Seems like it takes a long time to charge itself and also doesn't hold the charge for longer than two days or so, although I am not sure about that. It could have been available in other colors and eco-friendly materials than black and plastic.

Writing this review after 3 months of usage...
Power bank is gud. Charges my mobile for around 5 to 6 times per full charge...
But at times when charging my mobile , charging gets automatically cut off in spite of charge in the power bank showing 25 to 50 per cent remaining.. ( don know whether its due to mistake in the mobile or power bank ).

Have not used it still with one time charging of many gadgets..

Shall review again after some months

Bought this Product early in January via Amazon. Product was delivered on time with good packaging. The product works as expected. The device is heavy but sturdy. It has a LED display to indicate remaining battery life (25,50,75 ). The charging and connectivity is excellent. Overall good value for money.
