Power bank charging

[Ramesh Krishnamurthy9]

I recently picked up a power bank with an output of 5V-2A. The USB charger which came with the device has an output of 5V-1.2A. If I use the power bank to charge my N5, will it harm my device and affect the battery life?

Also request of somebody could help me out with the tolerance range for the USB charging?

Don't worry, it's fine. The current capacity of the charger is the charger''s limit, all it means is that the device can't pull more than that from the charger.
