Last year December, Oneplus announced the Oneplus Powerbank. It was launched in March 2015 and it is now available in India. The Oneplus Powerbank is nothing special on its own. But if you have a Oneplus One, it could compliment the mobile with its matching design. It is available in Silky While and Sandstone Black. It weights about 30 grams less than the Mi Powerbank and it is slimmer and has 2 USB ports to charge 2 devices at the same time. Both the ports output 2A for charging. It has the same lithium polymer battery type as in the Oneplus one. The battery capacity indicator is awoken by a gentle shake gesture and just like the Mi powerbank, it has the safety circuit to prevent over charging and overheating.
If you are interested buy the Oneplus Powerbank from Amazon India
It was available in Amazon for a introductory discounted price of Rs 979. But the launch price could be Rs 1399.
